Abstract

VALERIO, Ana L.  and  LAURITO, César A. Mammalia, Xenarthra (Cingulata) New records and confirmation of Pachyarmatherium Leiseyi Downing & White, 1995 record at Buenos Aires of Palmares, Alajuela province, Costa Rica. Rev. Geol. Amér. Central [online]. 2011, n.44, pp.131-139. ISSN 0256-7024.

New scute remains of Cingulata recovered from the Upper Cenozoic of Buenos Aires de Palmares locality are described. The small osteoderm founds confirms the presence of the Pachyarmatherium genus and its North American species at southern Central American. Besides, its association with the giant scutes of Glyptotherium arizonae permits to deduce a Late Blancan to Early Irvingtonian age.

Keywords : Cingulata; Glyptodontinae; Glyptatelinae; Blancan; Irvingtonian; Costa Rica.
