The fossil record of Pleistocene Proterotheriidae is scarce. It is restricted to the species Neolicaphrium recens known from Brazil, Uruguay, and Argentina, and to Uruguayodon alius, from Uruguay. Up to the date, proterotheriids are absent from the Pleistocene record of the Pampean Region. The aim of the present contribution is to report isolated remains of proterotheriids coming from Punta Indio and Punta Médanos localities, at the coast of Buenos Aires Province, Argentina. The specimens were found in the coastline and lack precise stratigraphical position. These findings indicate that Pleistocene proterotheriids were probably more diversified and geographically widespread than previously thought.
