Abstract

Dental and postcranial remains of Equus sp. indet. are described, originating from lacustrine sediments that crop out in the Buenos Aires de Palmares locality and surrounding areas. These findings establish an open paleohabitat with a predominance of grasses during part of the Irvingtonian and add a new component to the fossil fauna of this locality.
