[edit] Initial comment

72.134.44.224 20:47, 30 September 2006 (UTC)I'm not very experienced with Wikipedia, but I noticed that two categories were virtually parallel and should have links between each other. The Cambrian Category holds a mishmash of geologic periods, vertebrates and invertebrates. The Prehistoric Arthropods category holds several Cambrian arthropods that are not in the Cambrian category. So, I added several Cambrian invertebrates (some of them of uncertain classification, but it is much easier to find them in one unified category). It might make sense to have a sub-category in Prehistoric Arthropods for prehistoric invertebrates of uncertain classification, or vice versa. To try to make this little post understood so it can be discussed, I will post this in the talk page for Anomalocaris, Anomalocarid, Aysheaia, and Hallucigenia. Hope this helps Wikipedia's support of a nice little-known topic.

Perhaps we should make a category for prehistoric organisms of uncertain status, i.e., the weird thingamajiggers that we're unsure where they fit in the Tree of Life, like Dickinsonia, or Tullimonstrum?--Mr Fink 23:27, 30 September 2006 (UTC)
I think that would make the mess of categories a lot simpler, and so someone doing research on this kind of topic would have an easier time finding correlations between animals and periods.72.134.44.224 21:59, 31 October 2006 (UTC)

[edit] Images?

Since the "claw" is the most common fossil evidence (and looks quite different from the fossil of the whole animal), I think it would be useful to add an image of a fossil claw. Mel 128.138.167.212 (talk) 22:35, 8 January 2008 (UTC)

[edit] Classification of Anomalocaris (a possible one)

[edit] Consistency, please

This article lists Dinocarida as a member of Panarthropoda and Lobopodia. Opabinia and Amplectobelua articles lists it under the pseudophylum Problematica. Anomalocarid article lists dinocardians directly under Protostomia and so on.--JyriL talk 17:36, 15 April 2007 (UTC)

[edit] Phylum

In the infobox on the right side, it mentions a different Phlyum from what the article says it is related to in the first paragraph 207.6.125.46 (talk) 00:03, 28 January 2008 (UTC)

The group Lobopodia is related to Arthropoda, but that group is not a subgroup of Arthropoda.--Mr Fink (talk) 00:06, 28 January 2008 (UTC)
According to recent classifications (e.g. Briggs et al. 2008 Journal of Paleontology vol. 82, p. 240; see also Palaeo Database) the anomalocarids, and for that matter the whole class Dinocarida, are listed under the stem group Euarthropoda, i.e. grouping them with the Arthropoda, and not the Onychoporans and Tardigrada. I don't just want to change the classification, as it impacts on quite a few entries, but unless someone has reason to maintain the inclusion in the lobopods I'll change it.Rolf Schmidt (talk) 01:54, 24 April 2008 (UTC)

[edit] Merge

Could/should this be merged to anomalocarids? By my reading they're virtually identical, but I'm not a specialist. WLU (talk) 17:09, 20 March 2008 (UTC)

No, if only because this article talks about a specific genus of anomalocarid, whereas the article "Anomalocarid" talks about all anomalocarids. On the other hand, certainly, these two articles need to be individually expanded upon so that they differ in these respects.--Mr Fink (talk) 18:00, 20 March 2008 (UTC)
Ya, I re-read both pages and came to the same conclusion. Could I get an opinion on the expansion? Lots of reliance on Gould and Morris' popular books, just because I have them on hand. WLU (talk) 18:52, 20 March 2008 (UTC)
