Definition of uintathere in English:



  • An early fossil hoofed mammal of the Eocene epoch, with a heavy rhinoceros-like body and a grotesque head with several bony horn-like swellings and long canine teeth.

    • ‘Mammals included many giant yet small-brained rhinoceros-like types - the Asiamerican uintatheres, and brontotheres and the African arsinoitheres.’
    • ‘Eocene uintatheres sported several blunt pairs of horns that were probably covered by skin.’
    • ‘And next, I want to read about ‘exotic’ fossil mammals - uintatheres and Astrapotherium.’
    • ‘Many types of large mammals disappear, including all the uintatheres and brontotheres and indricotheres.’
    • ‘The large mammals such as uintatheres, pantodonts, and tapiroids may have been stream-side or marsh dwellers.’


Late 19th century: from modern Latin Uintatherium, from Uinta(h), the name of a mountain range in Utah, US (where remains were found), + Greek thērion wild beast.
