Uruguaytherium is an extinct genus of astrapotherid mammal from the Late Oligocene to Early Miocene of South America. It was named by the Argentinean paleontologist Lucas Kraglievich in 1928, from a fragmentary fossil found in the Fray Bentos Formation of the department of Río Negro in Uruguay, and the type species is U. beaulieui.[1] The related genera Xenastrapotherium and Granastrapotherium, which make up Uruguaytheriinae with Uruguaytherium, are also from South America, although them colonizated the equatorial zone.[2] The holotype specimen of Uruguaytherium is a partial mandible (the left mandibular ramus), with a preserved third molar, or M3.[3]
