Americatheria refers to a clade of mammals more closely related to Dasypus (today's armadillo) than to any members of Afrotheria (like elephants) or members of Boreotheria (like primates and rodents).[1] It was applied as a biogeography-driven name to denote the whole clade that includes both crown and stem Xenarthrans.[1][2]
Fossil evidence
[edit]Additional fossil groups, such as members of the extinct Peltephilidae and Glyptodontidae families,[2] corroborate all the more the South American origin[1] and diversification of the clade. Fossils of such groups are generally found in well-dated stratigraphic contexts, such as Bolivia's Salla Beds[1] and Argentina's Santa Cruz Formation, which yielded a rich fauna of early xenarthran fossils.
