1 88 Life of a Fossil Hunter 



been distinct, like the metacarpals and metatarsals 

 of the pig. With this idea in mind, I was con- 

 stantly looking for a camel in the older beds, and I 

 cannot express my delight when one day, as I was 

 exploring the John Day beds, I came across a skele- 

 ton which had been weathered out and lay in bold 

 relief on the face of a slope. I knew before I picked 

 up the cannon-bone that my belief was verified, and 

 when I took up the two bones separately, the fact 

 was proved beyond a doubt that in this ancestor of 

 the living form the metacarpals of the fore foot and 

 the metatarsals of the hind foot were respectively 

 distinct. As the species represented by this speci- 

 men was new to science, Professor Cope named it in 

 my honor Paratylopus st ember gi. A skull of this 

 species was afterwards found by Dr. Wortman, and 

 both specimens are now on exhibition in the 

 American Museum. 



I arrived at this conclusion with regard to the 

 cannon-bone of the ancient camel as Darwin, Marsh, 

 and Huxley arrived at the conclusion that the 

 ancient horse had three toes. They recognized that 

 the splint bones of the horse represented the side toes 

 of rhinoceroses, one on each side of the middle 

 metacarpals and metatarsals respectively, and they 

 decided that they were the remnants of side toes in 

 the ancestor of the horse. And later we also found 

 a three-toed horse.
