Fixed Goloboff et al., 2009 reference[edit]

The Goloboff et al., 2009 paper places Xenarthra as sister to Euarchontoglires, not Boreoeutheria. The Evolutionary History section describing this paper was changed to reflect this. — Preceding unsigned comment added by 128.255.128.55 (talk) 02:52, 23 February 2012 (UTC)


Edited Text[edit]

I edited the page where the links to "Vermilingua" and "Folivora" in the second paragraph of the evolutionary relationship section are located, by inserting, in parentheses, the common names for those families. It seemed to me that the formal Latin family names were unclear to readers, as they hadn't been presented before. I, myself, had to follow the links to see what the terms "Vermilingua" and "Folivora" actually referred to. I think by adding that Vermilingua = anteaters and Folivora = sloths the page is clearer and more useful. —Preceding unsigned comment added by 24.69.160.130 (talk) 08:17, 14 February 2009 (UTC)

classification needs work[edit]

The classification includes no fossil taxa, while showing extant forms in great detail, down to species level. I think we can improve this, since xenarthrans have some major, well-known extinct sub-groups.Cephal-odd (talk) 21:22, 27 September 2008 (UTC)

Atlantogenata[edit]

I was unclear in my edit summary. I removed the sentence "The Xenarthra are part of the super-cohort Atlantogenata" because the following sentence is "Xenarthra may be most closely related to either Afrotheria (in the group Atlantogenata), or Epitheria (comprising Afrotheria and Boreoeutheria)." Xenarthra cannot be both in Atlantogenata and outside Epitheria, where Epitheria includes Afrotheria. Atlantogenata means Afrotheria+Xenarthra. If Xenarthra is outside Epitheria and Afrotheria is in Epitheria, then Atlantogenata is not a valid clade. A flat statement that Xenarthra is in Atlantogenata (sentence 1) contradicts a statement that Xenarthra may or may not be in Atlantogenata (sentence 2).--Cam (talk) 18:54, 18 January 2013 (UTC)
