Abstract

GONZALEZ, Laureano Raúl  and  SCILLATO-YANE, Gustavo Juan. A new species of Stegotherium Ameghino (Xenarthra, Dasypodidae, Stegotheriini) from the Miocene of Santa Cruz province (Argentina). Ameghiniana [online]. 2008, vol.45, n.4, pp.641-648. ISSN 1851-8044.

A new species of Stegotheriini (Xenarthra, Dasypodidae), Stegotherium tauberi is described here based on materials previously attributed to Stegotherium tessellatum Ameghino, as well as additional specimens discovered recently. All the specimens came from outcrops of the Santa Cruz Formation (Santacrucian Age, late early Miocene) located between the estuaries of the rivers Coyle and Gallegos (Santa Cruz Province, Argentina). The materials reassigned here represent the most complete for the tribe Stegotheriini. Moreover, Stegotherium tauberi is the southernmost Stegotheriini discovered up to now.
