[edit] Cladistics

Your opinion on 'traditional' versus 'historical' should have a citation. The problem I have with this article is that it resembles a personal essay, and it is left reflecting the views of the WP editor who visited last. EdJohnston (talk) 21:45, 3 January 2008 (UTC)

Thanks for your reply. Your user name suggests you could be an expert in a biological field. If you know Unwin's book, and believe it could be a reference for the use of traditional taxonomy, perhaps you could add it to the article. It would be interesting to know if Unwin has 'cladistic' in the index! EdJohnston (talk) 01:05, 4 January 2008 (UTC)

[edit] Scale Chart

Hi, how do you do the scale charts?--4444hhhh (talk) 20:42, 4 January 2008 (UTC)

[edit] Theropod Speed

Hi Dinoguy, i hope you had a merry christamas and a happy new year. You said that juvenile rexes had more ornithimimid leg proportions, what size, weight or age did they lose these? Also the newest speed theory for a rex is 18 mph, what makes this estimate more reasonable then the theory of it moving 24-25mph or should the latter not be ruled out( it seems a little "unfair" on the rex that hadrosaurs get to wizz of at 28 mph). Also while im typing, although there is no evidence of maniraptorian theropods hunting in packs wouldnt it be easier and safer to live and work in packs? Although the deinonychus find shows cannabalism, couldnt that just be a fatal confrontation with another pack trying to steal the tenontosaurus meat? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 20:51, 7 January 2008 (UTC) I didnt mean the deinonychus having a turf war, more like hyanaes stealing kills of lions (or vice versa) but some members of th flock could have been to hungry to give up the kill and tried to protect it but were overpowered by the other pack. Also in the rex speed they had the same weight estimates (6-8 tonnes) for the 25 mph estimate as the 18mph one, and in the hadrosaurs, didnt they say it was certain tail muscles as they found it it had a muclier tail and backside and it was muscles their that powered its speed. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 16:01, 8 January 2008 (UTC) Also if maniraptorian theropods travelled in flocks wouldnt it make their hunting easier if they hunted together, if they live in flocks wouldnt it also mke more sense if they hunted together. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:31, 9 January 2008 (UTC) Hi dinoguy, with the rex speed estimates, if they had the same weight estimate (6-8 tonnes) why were they different or would that be all the "Technical Stuff" on the computer. Also, apart from Edmontosaurus and Anatotitan, what other hadrosaurs lived alongside rexes to match up to the dino mummys proportions and do they know its species yet? Rex Build In the article it states that to different rex types have been found, gracile and robust, while these could be gender or age related, could it be that it was area and prey species related. Could some of the more robust rexes be designed to attack bulky , armoured ceratopsians and are more likely to have the engage in combat ansd sustain injury with their prey while the more gracile one was designed to chase faster moving hadrosaurs and ornithipods? Or would thse be utter rubbish as all prey lived in the same area? Hey dinoguy, in your theropod size graph were you using different estimates? As the rex was 12 metres and the gig was 13, usually they are bigger than that in your size charts. One the one in the gig article is is new or has been changed becuase i could swear its different. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 22:53, 11 January 2008 (UTC) Hi Dinohuy, Thanks for answering my questions. On the gig article on the picture of the gig skull it states it is 47 ft long, is this the largest estimat because i thought the biggest was 46-45 ft long. Also have you seen arthur weasleys gig pic? I belive it should be on the article, what do you think. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 16:47, 12 January 2008 (UTC) Hi Dinoguy, in dino autopsy the hadrosaur running position was with its tail raised in the air and its front body closer to the ground with its arms tucked in, do you know what positions maniraptorian, tyrannosaur, and carnosaur theropods would have been in while running? Also the hadrosaurs was fast due to muscles in its tail, is there evidence of this in other dinosaurs? Lastly due to deinoychus sickle claws, the running speed has been reduced to no more than 20-25 mph, would this speed reduction apply to other maniraptorian theropods due to their sickle claws?Nice work on the new size diagrams by the way. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:50, 17 January 2008 (UTC) I was the guy who made the estimastes as on the news the velociraptor speed was 25 mph so i thought deinonychus would be similar. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 15:58, 18 January 2008 (UTC) Hi Dinoguy, my estimate for the deinoychus speed was more of a rough guess than a good estimate, and i was wondering it deinonychus may have been a little faster than i first thought. Velocirator's speed was 25 mph and deinoychus was bigger and had a longer stride length, would deinoychus have been faster than velociraptor? Also what science journels do you read fo dino info as i was wondering if i could purchase them anywhere. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 15:33, 19 January 2008 (UTC) Thanks for telling me were you get your dino info, it was on the news that velociraptor could run at 25 mph as it was the same computer that said rexes ran at 18mph and compsognathus, dilophosaurus and allosaurus speed was also tested. Thanks for telling me, if anything now i believe the rex estimates of 25 mph are more reliable, what do you think? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 16:06, 21 January 2008 (UTC) Hi dinguy, i was wondering about speeds of smaller hadrosaurs such as parasaurolophus and corythosaurus and have their been any studys? If not, what would you say a reasonable estimate would be? Also in your size charts deinonychus was 11ft, in JP3 the deinonychus were 13ft i found a size graph of all jp dinos and the JP deinonychus seem huge compared to the ones in your size graph whens its only 2ft. im finding a link for you but in the meantime what dou you think to my Questions (including the hadro speed one and the rex speed one you missed). Heres the JP link.http://www.jplegacy.org/encyc/dinosaurs/UltimateJPchart.jpg Thanks for telling me all you know, i doubt T-rex would be 8 tonnes in the first place, 7 yes, but 8 no. The most reasonable estimate for the biggest T. rex found(Sue) was 6.8 tonnes which is close to 7. The weight estimate they were using for 25 mph rex was 6-8 tonnes. Also with smaller hadrosaurus weighing around 2.5-4 tonnes which is much less than big elephants, which can run at 25 mph. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:32, 23 January 2008 (UTC) Hi Dinoguy in the utahraptor size graph it seems taller than in the giant birds one, also in everybook iv read with a size comparison the utahraptor always seems taller. You also said that its hard to get a good stencil for deinobychus, so why not use ArthurWeasly's picture as this would also give a good idea of the height which is not shown in the current deinonychus size graph(Im not saying its a bad size graph as like all the others its brilliant, its just doesn't show the height very well.) Lastly i read that you are making a Squamate size graph and im wondering how its going? I didn't mean to be nosey i just read it, i also wondered id i could help in any way as you said stencils would be hard to find( for the snakes i presume) and i have some good photos of komodo dragons from whn i went to indonesia in 2007 and i could search around for any good snake photos aswell. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 18:08, 23 January 2008 (UTC) Hi dinoguy, il upload the Komodo dragon images as soon as possible,but one thing first, how do you up load images? Also there is a background on them but hopefully that wont change alot. Ive found a link with a good deinoychus image although it doesn't have alot of feathers but hopeflly that won't change anything on th size graph. Heres the link.http://critters.pixel-shack.com/GalleryA.htm —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 15:56, 24 January 2008 (UTC) Hi Dinoguy il probably have the images uploaded by tommorow, have you seen the picture of the deinonychus in the link i gave you? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 15:54, 25 January 2008 (UTC) Hey Dinoguy, i was wondering about maniraptorain theropod feathers and most birds dont have feathered legs, their thighs are feathered but usually the have scaly legs and i was thinking this would be the case in "Raptors" also, although not all, some birds, usually birds of prey such as the Battleur Eagle(I think thats how you spell it) don't have feathered faces, most of their head is feathered but the featheres stop behind the eyes about, i wonder as they would need to use snouts to tear carcasses to pieces, tjis would be the case with "Raptors". This brings me on to my nest question, you said that wolves and lions don't care about the rotting meat trapped in their fur( although i think because they have fur not as much gets trapped in than feathers as usully its blood in the fur, not flesh.) Usually carnivores like wolves and cheetas are pack hunters and clean each other after hunts, this may support pack living and/or hunting and they may clean each other although this seems unlikely as they probably thought more like birds than mammals. Also you said large "raptor" foot prints were found fossilised, what made his footprints or don't the people who found them know? —Preceding unsigned comment added by 86.130.48.204 (talk) 17:23, 25 January 2008 (UTC) Hey Dinoguy, maybe it varied between raptors but unforyintaley we don't know for all yet, after reading what you said have any deinonychus fossils been found in Canada (Is Maryland in Canada i can never remember) and yes sometimes cheetas hunt in family groups but not all the time. Although they didn't need packs to groom, i still think they needed hunting together as the fighting dinosaurs fossil hardly shows the velociraptor getting off scott free. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 19:06, 25 January 2008 (UTC) Hey Dinoguy, do you have a high res image of the dave fossil? Also, hows deinonychus size grapg coming along?dId you have a look at the image on the critter-shack link, it could even be useful for other size graphs if you find a decent veiw. Hey Dinoguy, first off, i apologise i now i look back on the dragon images not all of their tail is seen, fortunatley theres a komodo dragon image on their thats in lateral view. Secondly you said thefighting dinosaurs gave evidence of velociraptor being a solitary hunter, not necciserily, the rest of the pack could have seen the sandstorm coming and fled,after the sandtorm they came back and fed on the protoceratops body(remeber it was missing limbs). Lastly great work on the new deinonychus graph, also when you get a good time and have finished the squamate graph, could you make me a smilodon populator graph? Sorry for any trouble it may cause. Hey Dinoguy, have you seen what i typed above as you haven't answered in a few days. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 18:49, 29 January 2008 (UTC) Hey Dinoguy, thanks for accepting the smilodon offer and giving me the dave pictures, i never knew you had a whole list of requests! Maybe you should have a request page like Arthurweasly, what other size graphs are you doing st the moment? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 19:04, 31 January 2008 (UTC) Hey Dinoguy, thanks for accepting the smilodon offer and giving me the dave pictures, i never knew you had a whole list of requests! Maybe you should have a request page like Arthurweasly, what other size graphs are you doing st the moment? D Hey Dinohguy, hows the smilodon graph coming along? I read one of your other messages, the one called Deinonychus(Sorry to be nosy), and i wondrred what is Senter (2006)? Hey Dinoguy, thanks for the great smilodon graph, looking at your deinoychus graph and comparing it with size comparisons in books yours is shorter but much more accurate of course, the ones in the book come up to an average humans shoulder, their neck isn't in an s shape at all its pretty much lined up with the spine. Why is theirs bigger, but not JP sized, also i found a skeletal diagram od deinonychus that had a shorter tail than in your size graph!Il see if i can find it but in the mean time what do you think to the deinonychus height in other comparisons? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:26, 9 February 2008 (UTC) Hey dinoguy, the diagrams wren't upright, just taller and its odd i could swear in the skeletal its has a shorter tail but then thats just me, did you use the diagram as the stencil for the graph? Also, in the diagrams in the book, one or two were fairly new and standing like in the skeletal diagram came up to the human shoulder but wre still 3.4 metres! it was odd but again what do you think to this? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 13:13, 10 February 2008 (UTC) Hey dinoguy, on closer inspection the graphs were slightly angled and that made them look taller, you also said they should be at 1 metre at the hip but is yours less than that? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 11:39, 11 February 2008 (UTC) Hi Dinoguy, great work on the Irritator graph, it looks great! Do you beleive that velociraptors claw could rip open a victim or were for stbbing into the neck, windpipe or arteries? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:06, 13 February 2008 (UTC) Hi Dinoguy! I was wondering, have any large theropod eggs ever been found? We know from fossils that hadrosaurs, ceratopsians and small theropods laid theirs in large clutches, do you think big theropods would have laid theirs in large clutches or small? Do you think they may have made a type os nest as well? Also is the DinoForum working on your compute? When you first gave me the link it was fine and the next day i was going to make an account, but the servers were down for ages and know all its is is a webpage with foreign writing on it, is this on your computer as well? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 12:25, 16 February 2008 (UTC) Thanks for tellng me. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:24, 16 February 2008 (UTC) Hey Dinoguy! I was wondering about biteforce, the lowest estimate for a rex is about 1-2 tonnes and the highest is about 4 tonnes, whic would you say is the most reasonable? A while back i asked you about spino bite force, a crocs skull can take alot of pressure and deal out alot of bite fotce and a spinos skull is built like a crocs and i was wondering how much bigger was a spinos skull than a crocs? I was also wondering if any carnosaur bite force tests had been done? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 16:30, 19 February 2008 (UTC) Hey Dinoguy! Have you seen my biteforce questiones above? I was wondering if you could please tell me what you use as the gig template in size graphs? Hey dinoguy!, did you see what i wrote as you haven't answered in for awhile now. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 19:31, 28 February 2008 (UTC) Hey Dinoguy! Are you busy as you haven't replied to me in two weeks now. And i was wondering, in the most northenly part of north america, how much snow would dinosaurs like a T.rex have seen? Also do you believe dinosaurs are warm-blooded(endothermic), i certainly do, if you read this please read and answer my other questions about bite force i left. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:28, 3 March 2008 (UTC) Hey Dinoguy, you pretty much anwered eveything. I was wondering what a good idea of a T.rex bite force —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:58, 6 March 2008 (UTC) Hey Dinoguy! I was wndering about dinosaur parental care, do you think all dinosaurs would have shown it, or if it would have varied between dinosaur types? Do you also think it was exhibited by bot parents or just the female/male? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 16:02, 11 March 2008 (UTC) Hey dinoguy! Thanks for telling me about parental care, i guess its one of the hardest things to estimate in dinosaurs but (for once) JP might og actually got something right, in the lost world, a pair of T.rex both help nuture the young, whilst in most popular culture its only the female and based on birds JP's estimate might actually be accurate! Also, i know allos had a weak but force but may have used high-speed attacks to use their jaw like an axe, and i was wondering if any allo speed tests had been done? I also remeber someone that a rex would hav had a bite force of tonnes and a gig had a bite force of 3 tonnes, do you think this is a good estimate? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 11:07, 20 March 2008 (UTC) Hey Dinoguy! When you read this please read the other things i typed above, anyways i was bored and read the T.rex talk page, and you said that the largest gig specimens(14 metres) were younger than Sue, sue was an elderly rex and a good deal bigger than younger rexes, this lead me to speculate that gigs might be even larger than 14 metres! If they are younger than sue then they could still get bigger, right? This lead me to believe new size estimates for a elderly gig, about 15 maybe even approaching 16 metres for an elderly gig, let me know what you think. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 20:54, 29 March 2008 (UTC) Hi Dinoguy, First of i noticed your new size chart, very good! Just one thing, i never heard of an 18 metre Megalodon, i only know 15-16 metre ones, do you know where and 18 metre estimate is? Also about Allosaurus, it had an over-engineered skull that couldn't break bone with mere bite-fore but would the impact of its high-speed "axe attacks" contain enough force to break bone? Also there are three species of Dilophosaurus i think, is there any size differance between them? If so then could you please make me a Size Graph of the Largest and smallest species of Dilophosaurus, a coelophysis and a Human? If you could, thanks and have you considered putting the Smilodon Graph on the article? I think it would look great. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 16:01, 5 April 2008 (UTC) Hi Dinoguy, thanks for accepting to do the size graph, i never new the smilodon articles had one until you told me yesterday. As for allos, differant theropods are designed for differant prey, a rex wouldn't reach the bone of a sauropod and would struggle to hunt, an allo wouldn't hav to much trouble with hardosaurs but would struggle on ceratopsians. Also, in ArthurWeasleys Allo drawing,i noticed the knees are the wrong way i think. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 16:52, 6 April 2008 (UTC) Hey dinoguy, i meant it like this, in your size graphs theropods legs are bent like bird's legs in a shape like this > but in AW's drawing, its legs are bent like a humans, in a shape like this <. Also on the Thylacosmilus article it doesn't mention its size, how big was it and what animal today matches it size? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:31, 9 April 2008 (UTC) OK, thanks for explaining everything. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 14:56, 10 April 2008 (UTC) Hey Dinoguy! I was wondering if dinosaurs, particulally maniraptorians, may have exibited sexual display plumage, like a pheasant or peacock? it was pretty much brought on by a doodle of a Velociraptor i did earlier, and i also wonder if they may have been other sexual dimorphism between dinosaurs? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 20:02, 10 April 2008 (UTC) Hey dinoguy, while were on the subject of feathers, do you think the males plumage would have been camoflouged or a more flashy colour? Do you also think they may have puffed out thei feathers to make themselves look bigger and more freightning when under threat? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 16:41, 11 April 2008 (UTC) Hi Dinoguy, just popped in to say great work on the Spino chart it looks great, and how is the Dilo chart coming along? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 16:31, 16 April 2008 (UTC) Thanks! It looks great, I'd put it on the article, quick before anyone else put another size graph like they did with the Smilodon. Its amazing how big Coelophysis looked in WWD, in real like it only came up to your hip, but in WWD it looked much taller, and on the Dilo article at the bottom of the page is a link called Dilophosaurus info, is that a real skeleton behind the man? I could swear its bigger than the one in your size chart. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 15:09, 18 April 2008 (UTC) I knew there was something odd about that skeleton, anyway i read somewhere, that a large dilo could be 6.5-7 metres, is this true? Also in the giant birds graph, you claimed deinoychus as a bird, do you think it was not a dinosaur at all and 100% bird, and would you say a deinoychus is morec closely related to a pidgeon than a triceratops? also, great work on the anomalocaris size graph! Interesting Stuff! Would you say some theropods are real birds, or that birds are actually dinosaurs? Aren't Dinosaurs, Crocs and birds part of a group called Archosaurs? —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 20:43, 24 April 2008 (UTC) No, actually! That makes things easier to understand, thanks.

Dunno if you already know about this or already have it, but I found the original description of Achillobator here. Happy New Year! Sheep81 (talk) 02:35, 11 January 2008 (UTC)

[edit] May I request you again a size chart? Sorry for any inconveniance.

Erm, sorry to bother you again, but I am having a debate about feather presence in Deinonychus anthirropus, and my opponents are using size as a counterargument. So, if you could, could you make another diagram with Deinonychus anthirropus, Struthio camelus (Ostrich), Aepyornis maximus (Elephant bird), Utahraptor ostrommayum, and Gigantoraptor erlianensis? This needs even less priority that the other one, so don't do it if you want, but, please, comunicate me if you don't do it. I appologice if I consume too much time out of your schuledude, and let me know if you feel I am abusing your stedyness. Eriorguez (talk) 18:02, 12 January 2008 (UTC)

I'll make sure to save both things you give me, as they are going to prove very useful in other debates. This one got ultimatelly won thanks to that. Thank you again.Eriorguez (talk) 14:53, 15 January 2008 (UTC)

Erm, it's me again. I'm making a work about crocodilians and their relatives, and, in the subject of the giant prehistoric species, a size chart would prove to be pretty helpful. I have over two weeks to make it, so take your time. In any case, if you could make a chart with Sarcosuchus imperator, Deinosuchus hatcheri, Gavialis gangeticus, Crocodylus niloticus and Alligator mississippiensis. That's it, if you can and have some good side views of those animals, I don't want to cause much trouble.

In any case, thanks for your time.Eriorguez (talk) 12:48, 2 June 2008 (UTC)

Well, good thing the situation was that favourable. In any case, this is excellent. Now, some self-made cladograms to show the relations, and done. Thank you. Eriorguez (talk) 12:03, 3 June 2008 (UTC)

[edit] Deinonychus

If it’s not too much hassle, could you send me Senter (2006). There’s no urgency, it would just be usful for paleoart reasons. Thanks. Steveoc 86 (talk) 20:10, 16 January 2008 (UTC)

[edit] Giant Birds Chart Problem

Hey. I just took a look at the recent chart of giant birds that you made. I think that it looks good, but you mixed up the color key for the Ostrich outline- green in key, red in image. Just a head's up. Rufous-crowned Sparrow (talk) 22:34, 18 January 2008 (UTC)

Hi, I like your chart too, but when did scientists added the Maniraptorians to the bird group? Will this be the case for all coelurosaurs?--4444hhhh (talk) 23:00, 18 January 2008 (UTC)
I have to admit, people are likely to find the name "Giantbirds" for this image confusing or controversial. -- Writtenonsand (talk) 01:02, 19 January 2008 (UTC)
Also, is that Deinonychus a little big? Deinonychus: "Based on the largest known specimens, Deinonychus could reach 3.4 meters..."
Yours is just about 3.4 meters wide in the graphic, but if it were stretched out straight it would be more like 4 meters.
And hey, come to think of it, could D. even curve its tail like that? -- Writtenonsand (talk) 01:08, 19 January 2008 (UTC)
Even though I support the theory that the maniraptorians (and probably the coelurosaurs) belong to the bird group, there is no genetic-evidence of Gigantoraptor or other maniraptorians of being birds (the only way that may make them birds is feathers). Right now the elephant bird is holding the record for heaviest bird of all time.--4444hhhh (talk) 05:46, 19 January 2008 (UTC)

I'm using "bird" in the vernacular sense here, which, according to my dictionary, means a warm-blooded egg laying animal with feathers and wings. All the animals included match that criterion. "Bird" is not even a taxonomic group, as Amphibia is, so actually calling Deinonyhcus a bird is *more* appropriate than calling, say, Tiktaalik an "amphibian". It's correct from a descriptive standpoint, if not a cladistic one. And I don't think "bird" has been given a phylogenetic definition. Anyway, I wouldn't do this for an image intended for Wikipedia. This was done as a private request (see above) and not intended for use in an article. I can't imagine how it would be useful in any article given the totally random assortment of birds... so I felt I had room to give it extra 'personality'. I almost used CZJ instead of Voyager Dork as well ;) As for Deinonychus, you're right, it came out a bit big, but that represents about the max flexion of the tail, as far as I know, or did when the artist drew it. Finding a decent profile view of this animal is nearly impossible... And 4444hhhh, how are you defining bird? Aves sensu Gauthier? Sensu Sereno? Sensu Charig? Or maybe Avialae sensu Gauthier? Or sensu Senter? Dinoguy2 (talk) 13:20, 19 January 2008 (UTC)

Updated. Dinoguy2 (talk) 13:46, 19 January 2008 (UTC)
I think that "amphibia" is also an abandoned taxonomic group with no formal scientific use now.--Draco ignoramus sophomoricus (talk) 11:45, 29 May 2008 (UTC)
Well to me, I defined birds has "any animal that has feathers is consider a bird". Oh, and what meant on my sentence is even though I like the idea the maniraptorians are consider birds then dinosaurs, there is no genetic-evidence.--4444hhhh (talk) 14:23, 19 January 2008 (UTC)
That's the Charig definition, which is the oldest. I agree with that also, but most modern scientists use Sereno's definition (common ancestor of modern birds and Archaeopteryx). There's no genetic evidence for any Mesozoic birds or dinosaurs--we don't have their genes! In terms of phylogenetic evidence, all maniraptorans are birds under that definition. And also dinosaurs--all birds are dinosaurs, but not all dinosaurs are birds. Figuring out which dinosaurs are birds is pretty easy, but varies based on what definition you use. Dinoguy2 (talk) 16:45, 19 January 2008 (UTC)

"I wouldn't do this for an image intended for Wikipedia. This was done as a private request (see above) and not intended for use in an article." -- Aha! That is a different kettle of Maniraptorans. In that case, this is none of my business. :-) -- Writtenonsand (talk) 17:59, 19 January 2008 (UTC)

You're right. Most of your other scale charts include "Voyager dork" Actually, You are talking about the drawing of a man more famous on the Pioneer plaque. And, since he isn't greeting ET, why is he waving and not running for his life from hungry theropods? :) T.Neo (talk) 18:51, 15 April 2008 (UTC)

Gah, can't believe I mixed up the Voyager gold record and Pioneer plaque. Of course the "dork" (name coined by somebody else in the Gigantoraptor chart CZJ discussion at image review, not me) should technically be Pioneer Dork. But then it sounds like he should be wearing a funny hat and shooting buffalo or something. But yeah, as this is not meant to be completely encyclopedic I swapped him out for CZJ. Gigantoraptor would be lonely without her. Neither seem too concerned with the stampede of theropods they're usually facing--this is intentional social commentary. Make of it what you will. ;) Dinoguy2 (talk) 13:41, 3 June 2008 (UTC)

[edit] Palaeontography

Hey Matt, could you email me on john.a.conway@gmail.com - I have a project I'd like to discuss with you. -- John.Conway (talk) 16:02, 31 January 2008 (UTC)

[edit] Do you do non-non-avian dinosaurs?

I'm working on the Procellariiformes at the moment and am looking for some help illustrating a point. I need an illustration to show the range in size from the largest great albatross to the smallest storm-petrel. I guess the way to do it would be the conventional wings spread viewpoint (the one used to compare huge pterosaurs and albatrosses to biplanes), with a human with arms out to provide a sense of the thing.

[edit] Help

Hi Matt. I've seen your scale diagrams and I think that are really better than the ones I did, so I want to know which program/s you use for create them with that form. Thanks. Cheers. Dropzink (talk) 09:37, 29 February 2008 (UTC)

But I have a problem, I can't found the exact size of the animal I want to compare in a scale diagram. It's Dunkleosteus, some sources says that reaches 8-10 meters, while other 6 meters. I was working on the article of spanish wikipedia and I think the info there can be a bit wrong. Also because I don't know how many species the genus has. But what I can do? It's difficult to find the most needed papers:( I've seen that you're an expert, not only in the dinosaur field, but in general paleontology, and if you have access to good Dunkle papers, I will be grateful if you give me some important data from them. Thanks again. Dropzink (talk) 04:39, 1 March 2008 (UTC)
I have another doubt. It seems that some Dunkle papers have contradictions. Like these, here, it says that D. intermedius is the type species, while here, that D. terrelli is. And about the length, I didn't found a paper indicating a size of 8-10 meters, all the papers mention specimens of 6 meters. Excuse me if you feel bothered. Thnx!;) Dropzink (talk) 22:54, 2 March 2008 (UTC)
Do you have access to JSTOR? There are very important and neccesary papers about the species and nomenclature. Dropzink (talk) 19:55, 3 March 2008 (UTC)
I was seeing the papers of the AMNH Digital Library. They describes a lot species of Dunkleosteus, but I'm not sure if including them cause the papers are old and is very probably that latter studies made invalid or doubtful those species. What do you say? Dropzink (talk) 10:05, 4 March 2008 (UTC)

[edit] Scale chart for Megalodon

Hello dinoguy2. I have noticed that you are a very talented person and I want some help from you. I request you to develop a scale chart for Megalodon and the requirements are as follows:

  • Megalodon shark, which should be 18 metres (60 feet) long (as this is a widely accepted estimate now.)
  • A Great White Shark, which should be 6 metres (20 feet) long
  • A 6 foot man.

Here is a source, which might be helpful for you: Megalodon information from SDNHM.

Your help will be greatly appreciated.

[edit] Image used on NG channel

  • Hey, I watched some programme about metabolism on National Geographic channel, and they had this kind of collage of images showing different life forms, and I noticed that they had used this image you've taken, or one that looked exactly like it: [2]

So I believe they've simply been scavenging the web for free images to use, and found that one on Commons. So well, that's pretty cool, if it was that picture indeed! Funkynusayri (talk) 00:40, 10 April 2008 (UTC)

  • Similarly, I looked for images of Nyctosaurus, because I wanted to fix this image: [3] (Is it correct now, by the way?) So I found this site[4] which sells fossil replicas or something, and noticed a print of your drawing of Nyctosaurus[5] is used, on the right of this image: [6] And uh, that's kinda funny too, images on Wikipedia sure get around! I still get impressed when I see pictures uploaded here used in other contexts for some reson... Anyway, is there a chance that your Nyctosaurus image will be fixed so it can be used in the article, it's a pretty cool image. Funkynusayri (talk) 17:38, 4 June 2008 (UTC)

[edit] Taxobox and circumscriptions

My comment on talk:Bird was partly driven by some recent happenings on Uniramia. It turns out the namehas been used for a Phylum, then for a Subphylum, for a clade and then finally kind of unused and in limbo. The taxobox ultimately has been removed as in the fish article. Is there a way of using a taxobox in this case ? Shyamal (talk) 14:31, 11 April 2008 (UTC)

Your Opinion is More Important than You Think Barnstar
Please accept this barnstar as a token of my gratituity for your valuable opinion on what to do with Uniramia, the obsolete taxon. Although you may not know it, and probably very few people know it, your opinion has helped shape the now-improved article. Why don't you stop by and have a look at it?

[edit] possible

Hey there, Im doing a report on Spinosaurus and I noticed you make excellent scale graphs.

[edit] Carnivorous Ceratopsians?

Hey Dinoguy! I read an article about ceratopsids, (heres the link:http://www.flickr.com/photos/markwitton/522293984/in/set-72057594082038700/) and it said that there is slight possibility that ceratopsians may have been omnivorous, if the read the link the weirdest thing is it actually makes sense! In droughts hippos have been known to chase lions and crocodiles of herbivore carcasses, so in a really bad Creataceous drought, and needs must, do you think a ceratopsian may have chased tyrannosaurs of hadrosaur carcasses? Also in the fighting dinosaurs fossil, Mongolia was a desert, right? And in deserts if there is a drought thats bad enough, some animals well do anything, right? well, in the fighting dinosaurs, out of the Protoceratops and the Velociraptor, who was the one squirming on the floor, kicking madly with his claw to try and save his own skin... —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 18:56, 10 May 2008 (UTC) Insteresting stuff, don't the deer and sheep live on islands that lack certain minerals so they eat the baby seabirds? Anyway, the elephant thing is just scary, i also have a question about raptor brains, would you say the more like a birds or a crocodiles?Bamboozlingbert21 (talk) 15:39, 15 May 2008 (UTC) Interesting stuff, if they brains are like a bird, they would eat like a bird. this ties with my Raptor bald head/neck theory(i don't want to start our arguement again), but you have to take in two factors, the shape of the raptors head, and the size off its prey, eagles don't have bald heads as they eat small prey such as fish and rabbits which are easy to disembowel, vultures eat large prey that they need to shove their head into, then theirs the shape of the head. Velociraptors tackled large prey but had a long snout that could have probed into carcasses. My idea is, smaller raptors may have had completely feathered heads as they ate lizards etc, although Velociraptor had a feathered neck but not head as it probed into carcasses with it's snout. Deinonychus and Utahraptor took on large prey like Tenantosaurus and Iguanodon, with short snouts, they had bald heads and necks but males may have had a crest of feathers or quills for display that could be flattened when feeding, they may also have had a neck ruff/mane similar to some vultures, also other parts of the body on all raptors may have been scaly, such as the legs, as all birds have scaly legs, and the hands, so the feathers don't get messy or in they way when hunting or carrying things. What do you think?Bamboozlingbert21 (talk) 21:34, 25 May 2008 (UTC) I think my assumptions about what they ate are reasonable, lions have short fur and a rough tounge thats very good at cleaning, they also don't shove their heads right inside the carcass unlike vultures. Have you seen they new weight estimates on the Dinosaur Size article! They list a charch at 15 tonnes, a gig at 13 and a rex at 9! What do you think? I think they are way too heavy personally. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 21:40, 27 May 2008 (UTC) You added them!? What was the method used to estimate as i still think they are too heavy. My speculation about feathers comes from their brain, if had had a bird's brain and ate meat, it ate like a vulture. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 09:09, 28 May 2008 (UTC) But not all vultures eat meat. Anyway, about the weight, im taking it with a 5t grain of salt alright, Gigs and Carchs were only 2-3 metres longer than a rex, but weight 5-7 tonnes more, and were meant to be lightly built! And im having difficulty believing a rex could be be "Built for Speed" and weigh 9 tonnes and only just go over 10 mph, let alone 25 mph tops! Since you said you thought they were a bit big, what would you say a more reasonable etimate would be? How would they catch prey? Hadrosaurs and iguanodons could have been fairly fast moving, ceratopsians are a grey area when it comes to speed, but have the pontential to move faster than they look with their rhino like physique. How would a 9 tonne rex, 15 tonne carch or 13 tonne gig, chase down prey!? Sure gigs and Carchs may have hunted sauropods, but a ceratain amount of speed/ agility is required to avoid injury from them which is unlikey with these weight estimates, if you believe them, most large theropods were probably almost pure scavangers. Well, i guess we all believe differnt estimates, i believe we should take alot of things about dinosaurs, like weight, speed and other things with a 5t pinch of salt until we have concrete evidance for them, the only thing that can give us evidence is the only thing we will never have, a living dinosaur. Btw, great work on the new quetzal size graph, on the subject of azdarchids, did you hear that many scientists now think they were bad fliers, and lived mostly as ground dwelling quadrupeds, feeding in marshed and mud flats but scavanging carrion when the oppurtunity came.Bamboozlingbert21 (talk) 08:49, 30 May 2008 (UTC) Wow, they seem so much smaller when flying, the comparison with the man and Hatzegopteryx was the one they used in the paper. Also may i request another size graph from you? This is your first modrn day request as it is for the Nile Crocodile called Gustave estimates are unsure of his size, but it is likely he is 25 ft long, the largest nile crocodile ever recorded, i want an idea of his size compared to people so you graphs came to mind immediatly, it would be extremly useful and would be good on the article too. If you could do it, Great! and thanks in advance. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 10:15, 30 May 2008 (UTC) Thanks, the chart is great, don't worry to much about his size so long as its 6-7 metres. Gustave is the largest, smartest and mpst resilient nile crocodile ever, no one knows his exact size as know ones measured him, he's to smart for all their traps, again, thanks. —Preceding unsigned comment added by Bamboozlingbert21 (talk • contribs) 17:35, 3 June 2008 (UTC)

[edit] Fossil range

Okay, I can back off on that. Just to get an idea of what you want, here are a few odd ones I came across-- what is the generally accepted way to do the following?

Let me know. I'll work on fixing my mess sometime in the next day. Thanks for flagging me before I made an even bigger mess! Bob the Wikipedian (talk) 22:13, 12 May 2008 (UTC)

P.S. Found another odd one from Grasshopper: Phanerozoic (Permian-Triassic, 250mya) to Recent
Bob the Wikipedian (talk) 22:18, 12 May 2008 (UTC)
I have fixed all instances I worked on (didn't take more than a few minutes, thankfully!), except the grasshopper and the species which went extinct during the Quaternary with no prior fossil record (or fossils dating back only to 1600s, 1800s, 1900s), mostly marsupials and a manatee. Let me know what I should do with these. Bob the Wikipedian (talk) 23:00, 12 May 2008 (UTC)
Okay, I've removed a few "Quaternary" lines from most of the articles I wokred on and kept "Recent" in only the ones of which we actually have fossils (Rodriguez solitaire, two wallabies, and a kangaroo rat). I'm assuming (by the definition on Fossil) that found bones, kept skulls and artificially preserved bodies count as fossils, so long as the animal is extinct. Still unsure what to do about that grasshopper. Thanks for helping me keep Wikipedia sane. Bob the Wikipedian (talk) 00:26, 13 May 2008 (UTC)
Apparently insect fossils are common in the P-Tr extinction event. According to Changhsingian, the extinction occurred during the Permian, and immediately after would have been the Triassic. I'm thinking "Late Permian" is adequate.
Looks like I made more mess than I thought-- I see you're replacing "to" with hyphens. Thanks for being friendly about all this. It's not often that I can upset someone and yet they act forgivingly. Makes me want to go look for a barnstar after I clean up the mess. Unfortunately, this mess will probably have to wait until tomorrow, as I need to look for a better job yet this week. Bob the Wikipedian (talk) 01:02, 13 May 2008 (UTC)
That's funny...I didn't revert any of those back to mid-Cretaceous. I actually thought I was helping clean up poorly done fossil ranges. Maybe my unknowing action will help the push. Bob the Wikipedian (talk) 02:34, 13 May 2008 (UTC)
Guess what? No more "to"'s, (however you format that...), all hyphens now! Thanks for letting me know ASAP. I've also posted a new discussion at WP:TOL in hopes of resolving the whole molecular-divergence-appearing-in-the-fossil-range thing. Bob the Wikipedian (talk) 14:23, 13 May 2008 (UTC)

Hi Dinoguy2, Sorry for the confusion over the disambiguation links for Reptile - Sauropsida. I was attempting to standardise the link for all pages. Never checked where sauropsid redirected to.

[edit] IGM

Hi Dinoguy2, Any chance of having a Wikipedia page for the Institute of Geology, Mongolia in Ulan Bator? So many fossils have IGM 100 numbers that it would be nice to have a list somewhere that could be added to as more fossils are added. It took me quite a while to even find out what IGM stood for, I dropped the acronym onto the IGM disambiguation page but there was nothing in Wikipedia for it to point to. Please put out the word that an extra dinosaur-related page for this is needed.Mollwollfumble (talk) 05:02, 1 June 2008 (UTC)

[edit] You once said Birds are technically reptiles.....

What did you mean by that? How are they technically reptiles? ScienceApe (talk) 01:12, 3 June 2008 (UTC)

I belive he said that because birds are also descendants of the last common antecesor of all extant reptiles. Also, Reptiles is what amniotes with do not belong either to mamalia or aves are classified. But, unlike mammals, aves are not basal to the whole of actual reptiles, but are actually a crown group of them. Not to mention, they are the closest living relatives to crocodiles; and both crocodilians and lizards are closer to them that to turtles. Take a look at the cladogram in the Reptile page:

Reptiles are a paraphyletic group. The group can be made monophyletic by including the birds (Aves).
Reptiles are a paraphyletic group. The group can be made monophyletic by including the birds (Aves).

...

Well, at least, that's the most reasonable explanation, and you were asking for the personal reasons of another person. But I guess this may be what he wanted to say. Eriorguez (talk) 12:11, 3 June 2008 (UTC)

Yup, that's pretty much it. See also my response on ScienceApe's talk. Dinoguy2 (talk) 13:45, 3 June 2008 (UTC)

Hey thanks for the info, but I thought that mammals did evolve from Reptiles? Like the Dimetrodon, and other mammal-like reptiles... ScienceApe (talk) 23:09, 3 June 2008 (UTC)

Interesting, thank you. If we went a little further, why don't they consider reptiles and mammals amphibians then? Since their common ancestor was amphibian like? ScienceApe (talk) 23:51, 3 June 2008 (UTC)
