classes

A list of all classes, not orders, in Archaea, Bacteria, and Eukaryota might be more manageable. Should we just change the name of this article of "List of chordate orders"? Arkuat 23:58, 2004 Jul 22 (UTC)

See Wikipedia:WikiProject Tree of Life. Arkuat 03:23, 2004 Jul 23 (UTC)

OK, so now it has expanded to a "List of animal orders" and has yet to branch out to even cover the Eukaryota. --Arkuat 05:54, 2005 Jun 21 (UTC)

This list had sat here for over a year with no information about non-chordates (except a link to Insect) on it. Order-level is too ambitious for a single article listing all such taxa; a comprehensive list of all classes would still be very long. For a list of phyla and selected classes, see User:Arkuat/Taxonomy. --Eric Forste (talk) 05:31, 26 July 2005 (UTC)[reply]

Other comment

I've just come across this page - an interesting idea.

At present, it only includes the phylum Chordata. Should it be renamed, or is the intention to include other animal plant and fungus kingdoms and phyla? If the latter is the case, it will need Kingdom and phylum headings, and will almost certainly need to be split at some stage. jimfbleak

A further thought. Extinct groups are included for fish, but not mammals, birds or reptiles (dinosaurs). What is the intention here?

another comment

I found the alphabetical order of classes disorienting; many people will be used to classificatory tables that give useful phylogenetic information. Should the list be arranged in branching order instead (or at least organised into subphyla)?

And how far do you concede to cladistics? The four tetrapod classes are SO antediluvian. Apparently the fishes have been split along cladistic lines, so shouldn't the avian orders be put into Reptilia on the same basis? Or the tetrapod, lungfish and coelacanth orders be merged under Class Sarcopterygii (fleshy-limbed vertebrates)?

And surely the agnathan orders need to be arranged into more than one class? - where are the hagfishes? I think I'd better insert them at class level before anyone puts them in with the lampreys.

Hope this isn't too negative. Just a few questions from an interested amateur with constructive intent. :) Gnostrat 21:30, 3 January 2007 (UTC)[reply]

Reptiles, birds and dinosaurs

I am hoping to add the dinosaurs to this list. I have a question, though. How can Archosaurs be a subcategory of reptiles if they include birds when reptiles exclude birds. Hoping somebody can help me out here especially as this conundrum in a number of wikipedia articles so it would be good to resolve this uestion, either here or through some offsite sources. ♫ SqueakBox talk contribs 04:58, 19 August 2015 (UTC)[reply]

Acipenseriformes

Why do Acipenseriformes are listed twice? I mean among Cladistia and again among Chondrostei. 178.235.146.101 (talk) 20:31, 11 April 2017 (UTC)[reply]

Tetrapods

There seems to be a glaring lack of extinct tetrapod groups. 178.235.146.101 (talk) 20:31, 11 April 2017 (UTC) — Preceding unsigned comment added by 2601:58C:C500:4CFE:DC82:7BBD:C581:D290 (talk) [reply]
