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]
