Adinotherium (meaning "not terrible beast")Palmer (1904) p. 80. is an extinct genus of toxodontid, large bodied hoofed ungulates which inhabited South America during the Middle to Late Miocene, from 17.5 to 6.8 Ma and existed for approximately {{Mya|17.5-6.8|million years}}, Santacrucian to Huayquerian in the South American land mammal ages (SALMA). Fossils of Adinotherium have been found in the Santa Cruz and Ituzaingó Formations of Argentina and the Chucal and Río Frías Formations of Chile.[https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=43391 Adinotherium] at Fossilworks.org

The approximately {{convert|1.5|m|ft}} long animal, with an estimated {{convert|120|kg|lb}} body mass, looked like a smaller version of its rhinoceros-like relative Toxodon.{{cite web |url=http://prehistoric-fauna.com/publ/bestiarij/adinotherium_ferum/1-1-0-121 |title=Adinotherium ferum - Бестиарий - Доисторические животные - Prehistoric Fauna |website=prehistoric-fauna.com |access-date=26 January 2022 |archive-url=https://archive.today/20120714134805/http://prehistoric-fauna.com/publ/bestiarij/adinotherium_ferum/1-1-0-121 |archive-date=14 July 2012 |url-status=dead}} Its front legs were somewhat longer than those of its relatives, making its hip and shoulder height about equal. A small horn atop Adinotherium's skull may have played a role in the mating season.{{cite book |editor=Palmer, D.|year=1999 |title= The Marshall Illustrated Encyclopedia of Dinosaurs and Prehistoric Animals|publisher= Marshall Editions|location=London|page= 253|isbn= 1-84028-152-9}}
