Oreodonts were a family of ruminating artiodactyls containing a considerable number of genera varying from small to moderate size with none exceeding the size of a wild boar. They "had a short neck, elongate body, short limbs and feet" and besides size varied among their genera primarily in teeth and the shape of skull. [1]  Although some of the Oreodont species had as many as five toes, they bore their weight primarily on two of their hoofed-toes.

 

Oreodonts appear to have been very plentiful but limited exclusively to North America. Leptauchenia and Merycoidodon are the best known Oreodont species. [2]
