Abstract

Carnivores include more adapted to predation and the oldest fossil records date from the Paleocene of Asia, Europe and North America. The group is divided into two lineages: the Caniformia (ursids, canids, mustelids, procionids) and the Feliformia (hienids and felids). The mustelids have a wide geographical distribution, with the exception of Australia and Antarctida, with intense fossil record from the "Tertiary" of Eurasia, North Africa and South America and North America. The main objetive of this project is the study of the a fossil Mustelidae from the Upper Juruá River (Late Pleistocene) of Acre, Brazilian Amazon. The material to be studied was preliminarily assigned to the species Eira barbara. Along with the study and morphological description, comparisons with fossil and recent specimens of mustelids of South America, this project aiming to recognize characters of phylogenetic value, as well as its taxonomic status, in which contribute to the paleobiological understanding of the Mustelidade in the Brazilian Quaternary.
