84 Hunting Horned Dinosaurs 



near the top, and the other near the bottom of 

 the exposures. They lie usually ou a bed of clay, 

 as if they had been drifted in from a lake (into 

 which, they had been carried by a river) and 

 lined the shore in the mud. In some places I 

 secured hundreds, yes thousands of bones and 

 teeth of many species, as well as shields of 

 sturgeons and the enameled scales of gar-pikes 

 as perfect as if picked up along a recent lake 

 shore. There were also bones and shells of a 

 great variety of soft-shelled turtles, and others, 

 with beautifully sculptured shells; they range 

 in size from less than six inches across, to over 

 two feet. Crocodile bones, and the dermal, or 

 skin plates of plated dinosaurs, were common. 

 We secured hundreds of the pavement teeth of 

 the ray Cope called Myledaphus, also countless 

 vertebrae of the reptile Ohampsosaurus. Prob- 

 ably all the species of this rich fauna, are repre- 

 sented in these bone-beds. The fragments we 

 collected came in good play, when Charlie and I 

 mounted the Trachodon skeleton. As we were 

 able to restore the missing tail from the caudal 

 vertebrae we picked up in bone-beds in the Ed- 

 monton Series, near Drumheller, Alberta. We 

 found many horn-cores also in the bone deposits. 

 Although we found many of the long bones we 

 were unable to take up many on account of the 

 expense. First, the bone has to be located, i. e. 

 discovered. Then likely a road has to be built 

 to it in order to haul in to it plaster and water.
