Pachyarmatherium is a genus of extinct large armadillo-like cingulates found in North and South America from the Pliocene and Pleistocene epochs, related to the extant armadillos and the extinct pampatheres and glyptodonts.[1] It was present from 4.9 Mya to 11,000 years ago, existing for approximately 4.889 million years.
Taxonomy
Pachyarmatherium was named by Downing and White (1995). Its type is P. leiseyi. It was assigned to Dasypodoidea by Downing and White (1995), and tentatively to Glyptodontidae by McKenna and Bell (1997).[2][3] A cladistic analysis performed by de O. Porpino et al. (2009) led to the conclusion that Pachyarmatherium is a sister group to a clade consisting of Glyptodontidae and Pampatheriidae.[1] Oliveira et al. (2013) suggest that Pachyarmatherium is a possible dasypodid.[4]
