How come Artiodactyla are listed both here and under Placentalia? - 208.147.76.20 07:01, 11 Mar 2005 (UTC)

"Eutheria are mammals with a placenta like humans, mice or whales." Could somebody verify this? 193.198.140.35 08:37, 18 May 2005 (UTC)

[edit] Humans are both Placentalia and Eutheria?

How can Placentalia and Eutheria both contain humans, mice, and whales? —Joe Jarvis 18:23, 20 May 2005 (UTC)

It's two different naming conventions. - UtherSRG 18:32, 20 May 2005 (UTC)

used synonymously --83.64.176.82 1 July 2005 09:09 (UTC)

They are not. Placentalia does not include some extinct genera, as explained in nl:Placentadieren. Ucucha 11:53, 15 August 2005 (UTC)

[edit] Subclass Marsupialia?

Why is this stupid classification with a subclass Marsupialia used? The most generally accepted classification seems to be as following:

• Subclass Prototheria/Australosphenida
  • Order Platypoda
  • Order Tachyglossa
• Subclass Theriiformes/Theria
  • Infraclass Metatheria
    • Supercohort (or whatever) Marsupialia
  • Infraclass Eutheria
    • Supercohort (or whatever) Placentalia

I'm going to change things. Ucucha 11:53, 15 August 2005 (UTC)

Probably because of en:Mammalia. I'd check there or a related page for some info. - UtherSRG 12:02, 15 August 2005 (UTC)

See further en:Wikipedia:WikiProject_Tree_of_Life/Marsupial_poll. I think we should not follow this silly classification. Ucucha 13:39, 15 August 2005 (UTC)

Go for it. When MSW3 is out I plan envigorate Wikiproject Mammals so as to redo all of the Mammalian pages as best I can. I expect you'll be in on that as well. - UtherSRG 13:48, 15 August 2005 (UTC)

So now that you've started, you should finish it. Theriiformes does not drill down to Placentalia... - UtherSRG 22:49, 15 August 2005 (UTC)

[edit] Multituberculata

The Multituberculata link has now become orphaned, this must be remedied. I have tried this, but my edits have been reverted, so I leave it to you. 128.255.194.41

[edit] Explanation

• Theria are live-bearing mammals, including Metatheria and Eutheria.
  • Metatheria are mammals with a pouch like kangaroos or koalas.
  • Eutheria are mammals with a placenta like humans, mice or whales.
• Protheria are egg-laying mammals like platypus or echidnas (Monotremata). Prototheria is another name for the taxon that contains the Monotremata.

[edit] Unmentioned supertaxon?

What about (unranked) Synapsidomorpha? It seems to be including Mammalia among its subclasses. — Ti89TProgrammer 23:35, 9 June 2007 (UTC)
