Trigonias (Greek: "triangular" (trigonos), "ias" [denotes possession] [3]) is an extinct genus of rhinocerotid from the late Eocene ( Chadronian) some 35 million years ago of North America. [4] Trigonias was about 2.1 metres (6 ft 11 in) long and, despite lacking horns, looked a lot like modern rhinos. Its front legs had five toes (as contrasted with three in modern rhinos), the fifth of which was vestigial. [5]
A specimen of T. osborni was estimated to have a weight of about 391 kilograms (862 lb). [6]
