A new species of Eutatus Gervais (Xenarthra, Dasypodidae) from the Late Pleistocene of the Northern Pampean Region, Argentina (original) (raw)

A new species of armadillo, Eutatus crispianii sp. nov., is described from Late Pleistocene sediments of the Saladillo Formation in Santa Fe, Argentina. This study employs statistical analyses and geometric morphometrics to support the species description, highlighting morphological differences in fixed osteoderms compared to previously recognized species E. seguini and E. pascuali. The findings contribute to the understanding of Eutatus morphology and the evolutionary history of armadillos in the Pampa region.
