Abstract

EQUUS (AMERHIPPUS) NEOGAEUS LUND, 1840 (PERISSODACTYLA, EQUIDAE) FROM THE QUATERNARY OF PARANA STATE, BRAZIL. The fossil record of Equidae in southern Brazil is restricted to Rio Grande do Sul State and is represented by isolated teeth and fragmentary cranial and postcranial remains. This paper describes Equus (Amerhippus) neogaeus Lund from Parana State, where Pleistocene mammals are poorly known. The material is a left dentary with cheek teeth and was found in the Mangueirinha Municipality in a small alluvial terrace, associated with some remains of Gomphoteriidae and Megatheriidae. The presence of E. (A.) neogaeus suggests an open paleoenvironment with xerofitic vegetation, and could indicate a Lujan Age/Stage (late Pleistocene/early Holocene) for the assemblage fauna.
