the Vertebrate Paleontologists follow Cop6, and 

 Marsh in their views of these animals when, in 

 reality they are simply reptiles that have long

 tatives. The nearest being the lizards. 



I climbed the rugged buttes and ridges. Many 

 are entirely devoid of vegetation. Our work was 

 in a canyon four or five hundred feet deep and 

 measuring a mile from prairie to prairie, with 

 long creeks or coulees running back into the flats. 

 Their head branches spreading out like an open 

 fan, as on Sand Creek, exposing thousands of 

 acres of denuded rock to the sun. I was so for- 

 tunate as to find two more or less complete skele-

 much of the beautiful skin impression preserved. 

 The small scales, often mere tubercles, polygonal 

 in shape arranged like mosaic-work in a pave-

 some of these lovely scales. He calls the new 

 creature St'ephanosaurus, marginatus * or the 

 crowned lizard. Barnum Brown discovered a 

 wonderfully complete skeleton here, he gives it 

 the name of Corythosaurus casuarius. Because
