Abstract
Squamates are a common component of the present vertebrate communities of Northwestern Argentina, although their fossil record in this region is scarce. In the present contribution, remains of extant genera of squamates from the Pleistocene of Santiago del Estero Province (Argentina) are described. An incomplete hemimandible of the teiid lizard Tupinambis and a short section of a vertebral column of the boid snake Epicrates are recognized. The presence of Tupinambis and Epicrates in the Pleistocene of the Termas de Rio Hondo coincides with the current distribution of these genera. These records increase the knowledge on the Quaternary herpetofauna of Northwestern Argentina.
