PLATE CLV 



Type Skull op Megacerops bucco 



Plate prepared under the direction of Professor Cope. One-third natural size. (See p. 544) 



Megacerops {"Symborodon") bucco, type (Am. Mus. 6345a), Horsetail Creek, northeastern Colorado, Chadron formation. The 

 skull is crushed down, this somewhat increasing its apparent breadth. The horns are poorly preserved but may have resembled 

 those of the skuU figured in Plate CLVI. The enormous zygomata rival those of Brontotherium.
