Abstract


During paleontological surveys conducted in 2013 and 2014 in Quaternary deposits from Gruta do Urso cave, Tocantins State, eight isolated teeth and five postcranial elements of Equus neogeus were recovered. Absolute datings indicate that E. neogeus inhabited the surroundings of Gruta do Urso cave during the Last Glacial Maximum. The specimens probably represent very young individuals that died outside the cave, weathering prior to the final burial, with ontogenetic and taphonomic similarities. Here, wereported the first scavenger interaction of ursids and equids in South America fossil record.
