Uruguaytherium

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