Trigonias (Greek: "triangular" (trigonos), "ias" [denotes possession]) is an extinct genus of rhinocerotid from the late Eocene (Chadronian) some 35 million years ago of North America.
== Description == Trigonias was about long and, despite lacking horns, looked a lot like modern rhinos. The front feet bore 4 toes (as contrasted with three in modern rhinos), the fifth of which was entirely reduced. The median digit was already the largest, whilst the second and the fourth formed a symmetrical pair. The hind feet had only 3 digits.
