[edit] Biesbosch

Thank you for contributions to Biesbosch. There are some things I don't really understand, and I'd like you to explain: What are saltisch sea-arms? I guess it is a translation from Dutch, but it makes little sense in English. Can you refer to a source for the information, or explain what you meant?

Jens Nielsen 19:13, 13 May 2006 (UTC)

I've edited it again now, according to your explanation. I think the correct word for "sea-arm" would be inlet, or in some cases estuary - please see if that fits what you mean. Dutch 'zoutwater' is sea water in English. I'll have a look at the articles you suggested at some later time.

[edit] Radius of Galaxies

Hi, I'm the guy that tweaked some things in the M31 article. I've noticed that in almost all galaxy articles the words "diameter" and "radius" are used as if they have the same meaning. This is obviously not the case, so the value for "radius" is almost always given as the diameter! (e.g. a galaxy with a diameter of 10.000 lightyear is stated to have a radius of 10.000 lightyear instead of 5000) I have corrected this in a few articles, but everyone keeps doing it wrong. What could we do about it?

Hopefully I wasn't part of the problem. Usually if I can track down the user who keeps making a basic mistake like that (by means of the history tab) then I leave them a very polite note in their talk page. Most people seem to take it well.

I have another question. Athough my English is at a fairly good level, it is far from perfect (my native language being Dutch). I have a wide range of interests, and I like to participate where I can for Wikipedia. However, in some cases my edits are containing quite some spelling and grammar mistakes. Some (not very polite) users said to me in response that "I should go back to the Dutch-language wikipedia". What is your view on this issue?

I've seen some pretty bad errors and horrid writing by native English speakers on Wikipedia, and I'm hardly free from commiting mistakes myself. Your English skills seem reasonably good to me, so if you feel comfortable contributing in English then I think you should stick with it. Also you could probably contribute significantly by translating articles and information between English and Dutch. (C.f. Wikipedia:Translation into English/Dutch.)

Unfortunately there are a few ill-mannered people who participate in Wikipedia. Over time I've just come to accept that as part of life on the internet and I try not to let it upset me too much. Thank you. — RJH 17:33, 22 May 2006 (UTC)

[edit] Lunar craters

I'm not sure if you'd be interested in this or not, but I thought I'd ask. There's a project myself and others have been working for several years called "List of craters on the Moon". Most of the crater pages are also linked to a biography page about the person for whom it was named. We've got most of those biographical pages created, but there are still a few hold-outs that are proving difficult to find good information in English. Among these are several craters named after Dutchmen:

If you are at all interested in tackling these biography pages, I'd greatly appreciate it. On the other hand if those aren't of interest to you, then it's not a problem at all. Thank you!. — RJH 22:04, 22 May 2006 (UTC)

[edit] Globular clusters

Hi DaMatriX,

I noticed you added a paragraph to the morphology section regarding a "completely new type of star cluster in the Andromeda Galaxy". Do you have a reference for this? It sounds a lot like a stellar association, although much less dense. Also, since they are not technically globular clusters, wouldn't it make more sense to add that to the star cluster page? — RJH (talk) 15:20, 26 September 2006 (UTC)

I did find a source (A.P. Huxor, N.R. Tanvir, M.J. Irwin, R. Ibata (2005). "A new population of extended, luminous, star clusters in the halo of M31". Monthly Notices of the Royal Astronomical Society 360: 993-1006.)

Thanks DaMatriX. Now that I think about it, the globular clusters page probably needs a section on intermediate forms where the line is blurred between the different cluster types. I also need to add some comments about globular clusters generally having relatively low amounts of dark matter. — 14:26, 27 September 2006 (UTC)

[edit] Recommendation Concerning the Uintatheres

What's your opinion on merging Uintatheriidae with Dinocerata?--Mr Fink 02:54, 29 March 2007 (UTC)

Personally, I'd consider merging them, as one, both pages say pretty much the same thing, and two, whenever people talk of Gobiatheriidae, they always refer to the sole genus, Gobiatherium, and we already have Gobiatheriidae/nae redirecting to the genus.--Mr Fink 16:14, 29 March 2007 (UTC)
You want the honor of merging them, or do you want me to do it?--Mr Fink 16:45, 29 March 2007 (UTC)

What sort of beasties you need? At the moment, I'm in a Paleozoic frenzy.--Mr Fink 18:37, 29 March 2007 (UTC)

I'll put the dog-bear and proto-seal on my list, then. I'm also doing Cenozoic animals, too, depending on my muse's mood.--Mr Fink 20:31, 30 March 2007 (UTC)

[edit] minor taxa

Please only list minor taxa between the article subject and the next high major taxa. Minor taxa should not be used otherwise, lest we overly clutter the taxobox. - UtherSRG (talk) 15:35, 24 April 2007 (UTC)

Am I not clear? I guess an example will clarify. If the subject of the article is an order, then it is appropriate to put superorder and subclass in the taxobox. If the article is about a family, then it is not appropriate to put the superorder or subclass, but suborder and superfamily are appropriate. Clearer? - UtherSRG (talk) 17:58, 24 April 2007 (UTC)

[edit] Bats

The problem with including bats in the list of mammals that apparently diversified during the Paleocene is that the earliest bat fossils are late early Eocene in age. So it may be that they diversified during the Paleocene. In fact, it seems that they should have. But, because that section in the Mammalia article mainly discusses "groups of mammals that appeared in the fossil record," (my italics) it seems that the only mammals that should be under individual time-period (epoch, etc.) headings are those with a FAD in that time. Hypothesizing that bats appeared in the Paleocene is probably a good bet, but that has not yet been verified by the fossil record. Tomwithanh 01:39, 3 May 2007 (UTC)

[edit] Bats part 2

You're suggestion sounds reasonable, and I'll be happy to check over however you wind up incorporating it, if you were thinking you'd want to do that. If I get some more time, I'll also be more than happy to more critically read the rest of that section; it just happens I'm most familiar with the bat record. Tomwithanh 00:55, 4 May 2007 (UTC)

[edit] Edit of Hyrax article

In this edit you added some (uncited) material about the creature's relationship to Elephants, with the final sentence "Citations would be helpful to wikify this article." You shouldn't leave comments about the article in the article.

I think you should have put the info that needed a citation on the talk page and discussed it there. --JamesHoadley 11:15, 5 June 2007 (UTC)

OK, thanks DaM --JamesHoadley 02:52, 6 June 2007 (UTC)

[edit] Evolution of mammals

I've added an article Evolution of mammals, because there's too much content to squeeze into the Mammal article. Please review and comment.

Once there's a reasonable degree of agreement about Evolution of mammals, I propose to reduce the "Evolution" section of Mammal to a link to and brief summary of Evolution of mammals.Philcha 11:39, 27 June 2007 (UTC)

Thanks for your prompt response!
I'll check the "Evolution" section of Mammal. Re many mesozoic mammals that are highly specialised, I know about Castorocauda (mentioned in Evolution of mammals because of fur, size, semi-aquatic lifestyle) and Repenomamus (omitted to save space). Are there others that are important enough to justify making the article even longer and, if so, can you point me to sources of information?
Re "two periods of rapid diversification: well before and well after the extinction of the dinosaurs", I thought I'd mentioned that under "Molecular phylogenetic timescale" and given a reference. Did I miss something? I deliberately placed all the theories based on molecular phylogenetics at the end: (a) I think they're interesting but not proven until backed up by fossil evidence; (b) I don't want to confuse readers by presenting two accounts of over 70M years of evolution at the same time, and thought it best to complete the "traditional" fossil-based story before dealing with the new ideas from molecular phylogenetics.
I'll also check out the "convergent evolution" material in Mammal.Philcha 22:16, 27 June 2007 (UTC)
