[edit] Another species?

I have a personal record of another species, L. clavinitialis. Can anyone else verify this? Ninjatacoshell 22:06, 12 April 2007 (UTC)

It's a juvenile of the type, last I checked. J. Spencer 22:11, 12 April 2007 (UTC)

[edit] GA Pass

Looks really good. I felt there was no COI as I had only done a typo and hadn't seen the article otherwise (what a nice surprise!). Nice and concise and yet fairly comprehensive. Prose good. Only thing I can think of is the ?L really bugs me but I can't see another way of writing it without some wordy explanation, though there is one further in the article, which then leaves minor problem of having one in the lead without an explanation. cheers, Cas Liber | talk | contribs 21:23, 13 May 2007 (UTC)

[edit] Good Article Review

I've listed this for Good Article review. While I think this article meets all the requirements personally, it's important to get community feedback and I'd like to avoid even the appearance of Conflict of Interest. Firsfron of Ronchester 17:25, 19 May 2007 (UTC)

[edit] OMG!

Man this one is looking pretty good for an imminent FA nom as well...what to do then...copyediting?cheers, Cas Liber | talk | contribs 05:14, 13 June 2007 (UTC)

This bipedal/quadrupedal, herbivorous dinosaur is known.. - What a tricky concept to term succinctly. This looks sort of ok and I guess we mean it could either be bipedal or quadrupedal. I'm not sure how others like the use of slashes like this.cheers, Cas Liber | talk | contribs 05:17, 13 June 2007 (UTC)

named, from Alberta (Canada), Montana (USA), and Baja California (Mexico), but only..

"From across western North America" (?) - better or leave as is. I'm not fussed just throwing up some ideas (well, not gastroenterlologically..)cheers, Cas Liber | talk | contribs 05:18, 13 June 2007 (UTC)

It's a bit lean in some sections, now that I look at it: lead, classification, paleobiology...; could use another image or two (a skeleton would be nice). J. Spencer 15:07, 13 June 2007 (UTC)

[edit] Update

OK, I've put some stuff into lead. Would be good to have another para eitehr underneath or connecting onto bottom of that one detailing what other dinosaurs come from that time. I am not sure what comes from where withni the separate layers of the formation.cheers, Casliber (talk · contribs) 05:10, 29 June 2007 (UTC)

[edit] To-do

Quick thoughts, in order of importance:

1. New scale diagram, to have both big L.? laticaudus and bog-standard 10 m Lambeosaurus
2. Species etymologies
3. Lengthened lead
   

J. Spencer 15:44, 31 August 2007 (UTC)

• Nice scale diagram - nice use of shadowed plain-colour figures. I'll take your word on the accuracy :) cheers, Casliber (talk · contribs) 13:38, 14 October 2007 (UTC)
• Added derivation of laticaudus, do you want paucidens as well? cheers, Casliber (talk · contribs) 13:42, 14 October 2007 (UTC)
• Added a sentence to the lead -feel free to tweak. The lead is as long as Parasaurolophus. Nothing sticks out as needing fixing overtly so nominate when ready. Justin let us know what you want the rest of us to do and I'm sure we'll do what we can. cheers, Casliber (talk · contribs) 13:50, 14 October 2007 (UTC)

Since we've got etymologies for the other three species in the taxobox, it would be good to do paucidens as well. And yes, L. laticaudus is huge, but nobody knows about it (they've also got supersized Kritosaurus in Mexico, although not quite as super; they made 'em big out that way). Otherwise, I'm ready to send this one in. J. Spencer 14:04, 14 October 2007 (UTC)

I don't suppose the skull of L. laticaudus is known, huh? It would be cool if some museum did a reconstructed mount. Standing next to a hadro skull three times as volumous as a human would be quite a thing! Dinoguy2 05:05, 15 October 2007 (UTC)

I think (I'd have to go back and check) that the lower part of the skull is known, but not the crest. Someone could probably make a decent mock-up, as lack of remains hasn't prevented skeletal mounts of Argentinosaurus, Saurophaganax, or "Seismosaurus". J. Spencer 13:51, 15 October 2007 (UTC)

It's about what I thought. You get a partial premax, maxilla, and jugal, but nothing much preserved above the lower margin of the eye socket. You can see that the premax is starting to steepen in front of the eyes, but what it eventually does is unknown. J. Spencer 14:52, 15 October 2007 (UTC)

I've added an external links section. I'm quite surprised this article didn't have one. As an encyclopedia, Wikipedia should be a place for readers to begin their research, and naturally some sort of external links should be included in the article. I'm certainly open to changes in the specific links I've provided. I tried to introduce links to non-commercial sites with some encyclopedic value, but the section isn't very robust at this point. We should also link to Wikispecies and Wikipedia commons in this section. J, do you know of some good books on Lambeosaurines that you might recommend for a "Further reading" section? Something along the lines of Dodson's book on ceratopsians?

I also made some very small adjustments to the text. I'm not sure how well the question marks in front of the dubious species in the body of the article will go over with regular readers, but if they must be included at all, it should be consistent. I've added some missing question marks for consistency. Please tell me if this is not appropriate. Firsfron of Ronchester 19:08, 14 October 2007 (UTC)

[edit] "Analogous to chewing"??

"... a sophisticated skull that permitted a grinding motion analogous to chewing." -- In what sense is it logical to say that L's dental processing of food was "analogous to chewing"? "Chewing" redirects to "Mastication", which says "Mastication or chewing is the process by which food is mashed and crushed by teeth." The American Heritage® Dictionary of the English Language: Fourth Edition online gives "chew 1. To bite and grind with the teeth; masticate." [1]. What L was doing was not "analogous to chewing", it was chewing. Or is there something I'm missing? -- 201.19.77.39 16:46, 15 October 2007 (UTC)

I've probably simplified it too much, but the action is different between mammals and hadrosaurids; mammals only have the jaw joint, and grinding comes from various motions at that joint alone, whereas hadrosaurids had other locations capable of motion, with the most accepted version being that the upper jaw bones bowed out when the upper and lower tooth rows contacted, grinding trapped material (the other option being the lower jaws rotated inward slightly). It's just a case of being very careful when applying mammalian terminology to dinosaurs, perhaps too careful. J. Spencer 18:03, 15 October 2007 (UTC)

Better to say "analogous to mammalian chewing," just to make this clear. Dinoguy2 23:58, 15 October 2007 (UTC)

Sounds good to me. -- 201.19.77.39 17:02, 16 October 2007 (UTC)

[edit] Changed tail on image

This image by a Russian illustrator, who has released it into the public domain, was unfit for the article due to an erroneous tail, I've tried to correct it, both versions are available on the right. Is it correct now, or should it be further tweaked? Funkynusayri 14:54, 25 October 2007 (UTC)

It certainly looks to be about within the range of possibility. J. Spencer 21:16, 25 October 2007 (UTC)

• Should I put it back into the article? Funkynusayri 23:48, 25 October 2007 (UTC)

I already did. J. Spencer 23:54, 25 October 2007 (UTC)

[edit] size graph

Im a little concerned with the the size graph in the article, it makes lambeosaurus look like godzilla. For example: compare the two images. 69.76.55.224 23:19, 30 October 2007 (UTC)

L. laticaudus was enormous, around 15 m/50 ft, and it should look odd and striking because few hadrosaurs got that big. Part of the difference is the pose of the lambeosaurs compared to the theropods, part of it is that hadrosaurs as big herbivores were chunkier by nature and bony anatomy than comparable theropods, and there's probably some variance to do with how the length was measured (along the curves vs. straight lines). Admittedly, the lambes are doing a bit of a high-step, but that's the artistic interpretation, and a traditional straight-on flat profile may be a worthwhile revision. J. Spencer 00:52, 31 October 2007 (UTC)

Hey guys, in case you wanted a more conservative pose for the size comparison, I whipped up a second option based on AW's Corythosaurus drawing (modified crests of course). Dinoguy2 11:41, 8 November 2007 (UTC)

I like the angle better on this new version, but either way, L. laticaudus was freakin' huge for a duckbill. It'd be kind of cool to make a diagram with the largest dinosaurs of each suborder together. J. Spencer 14:20, 8 November 2007 (UTC)

That would be cool, I'll see if I can get one together by tonight. Maybe using Argentinosaurus rather than Amphicoelias, so the other ones are visible ;) Dinoguy2 00:13, 9 November 2007 (UTC)

[edit] Duckbill bracketed?

Why is Duckbill bracketted in the lead? I haven't seen this in any other dinosaur article, so why now? I'm gonna remove it, but I just thought I'd post here first... (As it is, there's waay too many brackets in the lead anyway, and this just makes it seem like simple Wikipedia...) Cheers, Spawn Man 04:39, 8 November 2007 (UTC)
