Atlantogenata
Proposed magnorder of mammals From Wikipedia, the free encyclopedia

Atlantogenata ("born around the Atlantic Ocean")[5] is a proposed magnorder of placental mammals containing the cohorts or superorders Xenarthra and Afrotheria.[1] These groups originated and radiated in the South American and African continents, respectively, presumably in the Cretaceous. Together with Boreoeutheria, they make up Placentalia. The monophyly of this grouping is supported by some genetic evidence.[6][7]

Alternative hypotheses are that Boreoeutheria and Afrotheria combine to form Epitheria (as generally supported by anatomical and other physiological evidence) or that Boreoeutheria and Xenarthra combine to form Exafroplacentalia or Notolegia.[8]
Updated analysis of transposable element insertions around the time of divergence strongly supports the fourth hypothesis of a near-concomitant origin (trifurcation) of the three superorders of mammals: Afrotheria, Boreoeutheria, and Xenarthra.[9][10]
