New specimens allow revisiting the dental anatomy of Middle Miocene fossil primates from Patagonia

Abstract

Following more than 30 years of inactivity, recent field work at Cañadón del Tordillo has yielded a rich collection of fossils. Much of the recovered material consists of rodents, ungulates, and xenarthrans, but primates are represented by at least two teeth. The morphological study of these new fossils and the evaluation of their taxonomy and adaptive significance in the context of Patagonian platyrrhines are the goals of this contribution.
