Fig. 46.— Skeleton of Irish Deer. 
Artiodactyla [even-toed ungulates).— Tbk group is character- 
ized by having two large central toes divided in the middle {the 
cloven hoof), like the Hog, Sheep, Deer and Ox. Representing 
these is the very small jaw of Fantolestes, from the Eocene of 
Wyoming, in the large case. Also many skulls, teeth and bones 
of Oreodon, a much later form, in Case Q, Sects. 3 and 4, from 
the Miocene of the Judith River region. This animal resembled 
the Deer in its teeth ; but in form, size and character of feet, 
resembled the Mexican Peccary. There are also skulls, jaws and 
teeth of a larger form, Entelodon, also distinctly related to the 
Hog, in Sect. 8 of the same case, and from the same region. 
Of the true Ruminants, the skeleton of the Irish Deer, Megaceros 
Hibernicus, is a fine representative. This animal probably became 
extinct since the advent of man.
