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] PhylogenyCladogram based in the phylogenetic analysis published by Vallejo-Pareja et al., 2015, showing the position of Uruguaytherium:[2]{{clade| style=font-size:85%; line-height:85%|1=Eoastrapostylops |2={{clade |1=Trigonostylops |2={{clade |1=Tetragonostylops |2={{clade |1=Albertogaudrya |2={{clade |1=Scaglia |2={{clade |1=Astraponotus |2={{clade |1=Maddenia |2={{clade |1=Comahuetherium |2={{clade |1=Parastrapotherium |2={{clade |label1=Astrapotheriinae |1={{clade |1=Astrapotherium |2=Astrapothericulus }} |label2=Uruguaytheriinae |2={{clade |1=Uruguaytherium |2={{clade |1={{clade |1=Hilarcotherium |2=Xenastrapotherium }} |2=Granastrapotherium }} }} }} }} }} }} }} }} }} }} }} }} ReferencesFurther reading
