CHAPTER VII
Leontinidae
This family was established to include a group of large, heavily built ungulates, not unlike rhinoceroses in form, which have rooted teeth, the molars being similar to those of Rhinchippidae, i. e., composed of a wall and an anterior and posterior lobes, but with the cristae either lacking or little developed; and with the second upper, and the third lower incisors developed into tush-like caniniform teeth. Two genera are especially abundant, Leontinia of the Deseado beds, and Colpodon of the Colpodon beds, the former with the formula
