Adinotherium (meaning "not terrible beast")[2] 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 10.7 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.[3]

Description

The approximately 1.5 metres (4.9 ft) long animal, with an estimated 120 kilograms (260 lb) body mass, looked like a smaller version of its rhinoceros-like relative Toxodon.[4] 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.[5]
