Classification

edit

The interested non-specialist needs to know how this classification relates to the McKenna/Bell classification, if it does. The development of these mammals has been mysterious and much debated, hasn't it? Why not mention that?User:Wetman As Wetman said it would be good if we let go of all of this. This seems to be describing orders essentially different.User:Kai Barry 2

Live for me on check just now, but the page itself is marginal to empty; might just as well be a dead link.Jackrepenning (talk) 22:33, 4 December 2007 (UTC)Reply

Extinction?

edit

A caption in the gallery says

The desmostylians are the only extinct marine mammals

AFAIK they are indeed extinct, but there are other extinct marine mammal species as well, aren't there? Pinniped alone lists 22 extinct groups. Maybe it means "the only extinct order of marine mammals"? Jackrepenning (talk) 22:43, 4 December 2007 (UTC)Reply

Well, yes. Order. That's what it says. —Preceding unsigned comment added by Torwyn11 (talkcontribs) 02:47, 6 October 2009 (UTC)Reply

To the person who keeps adding Dinocerata and SANU...

edit

There has been recent systematics incorporating genetics, new fossil specimens, and morphological characters have found the litopterns to be closely related to perissodactyls. To have them included as paenungulates is wrong at this point. The rest of the South American native ungulates is up in the air, hence the tentative placement of Sudameriungulata here. As for Dinocerata there has yet to be a new publication to support their placement as members of the paenungulates. Thank you. 4444hhhh (talk) 05:02, 23 September 2021 (UTC)Reply
