Abstract
Santiago Roth (1850–1924) was a naturalist that collected and sold fossils from the Pampean region (Argentina) in Europe. Much of the specimens collected by Roth are hosted at the Paläontologisches Institut und Museum, Universität Zürich and Muséun D’Histoire Naturelle of Geneva in Switzerland, but were never studied. In this article, we review the specimens of the order Carnivora under a taxonomical and temporal approach. We confirm the presence of 16 specimens of Carnivora collected by Roth between the provinces of Santa Fe and Buenos Aires. We identify felids (Smilodon sp., Panthera onca, and specimens related to these taxa), ursids (Arctotherium sp.), and canids (Dusicyon avus and specimens related, Lycalopex sp., and Caninae indet.). According to the information reported by S. Roth, all materials are from the Pleistocene of the Pampean Formation. However, given the scarcity of data, only the specific age of few specimens could be more accurately established.
