Talk:Eutheria

There is something wrong here.

Xenarthra is also placed under Placentalia. Dan Koehl 10:24, 3 Apr 2005 (UTC)

Xenarthra is used here as the superorder, but at Placentalia as the order. I think these pages should be merged, like Metatheria and Marsupialia. Ucucha 18:18, 9 Apr 2005 (UTC)

Explanation

Eutheria includes:

• A few extinct genera.
• Placentalia
  • Xenarthra are animals with joints unlike other mammals, like anteaters, sloths, and armadillos.
  • Laurasiatheria 7 orders of mammal, including, bats, cats, horses, dolphins. All 7 orders were originally found in the supercontinent Laurasia
  • Afrotheria includes Paenungulata (elephants, Sirenia and hyraxes), Afrosoricida (tenrecs and golden moles), Tubulidentata (aardvarks), and Macroscelidea (elephant shrews).
  • Euarchontoglires includes Rodentia, Lagomorpha and the Euarchonta, a clade consisting of the Scandentia, the Primates and the Dermoptera.

The whole thing is a mess, and needs to be greatly simplified for our purposes, eliminating clades and keeping only the standard Linnean ranks. Stho002 (talk) 00:00, 7 November 2014 (UTC)

Then what do we do about 70 million years of nonplacental Eutherian mammals? Zyxwv99 (talk) 03:25, 17 February 2015 (UTC)

Just remembered, Eutheria has been Linnean since the 19th century. Zyxwv99 (talk) 14:26, 17 February 2015 (UTC)
