Trogontherium cuvieri grew larger than living beavers , with a skull up to 21 centimetres (8.3 in) in length, but was smaller than Castoroides. The incisors are covered in fine longitudinal grooves, and have a convex enamel face. The cheek teeth are high crowned. The sagittal suture of the skull is flanked by two deep depressions.
Castoroides (from Latin castor (beaver) and -oides (like) [2]), or the giant beaver, is an extinct genus of enormous, bear-sized beavers that lived in North America during the Pleistocene.
