Tritemnodon ("three cutting teeth") was an extinct genus of placental mammals from extinct order Hyaenodonta, that lived in North America during the early Eocene.[6][7] Fossils of Tritemnodon agilis have been found in Utah and Wyoming (Willwood Formation of Big Horn County and the Lower Bridger Formation of Uinta County). It was the size of a wolf.
