116 On the Judith River, Montana 



ranch), were the fireworks thrown into the sky 

 at Kendall, where the people were celebrating. 

 We made a camp later, on an eastern branch of 

 Dog Creek, called Taffy Creek. We made a thor- 

 ough study of this region near camp. During 

 our trip up Dog Creek we had made extensive 

 collections of invertebrate fossils from all the 

 different horizons, securing also Myledaphus, 

 and other sharks teeth from the lower Eagle 

 Creek sandstones which, with the Claggett 

 shales, form the lower beds of the Belly Eiver 

 Series of Alberta. On the south side of Taffy 

 below a large timbered hog back upheaval, I 

 found a locality in the Judith river bed that is 

 possibly the type locality from which Cope and 

 I secured our collections on that memorable ex- 

 pedition of 1876, when we found the first of the 

 horned dinosaurs (except loose teeth). A "blow 

 out," as they call it in the west, had exposed 

 along a narrow slope of sandstone, many bones 

 and teeth of horned, plated, duck-billed, carniv- 

 erous dinosaurs, with the teeth of Myledaphus, 

 and many broken turtle shells, as well as bones 

 of Campsosaurus, scales of ganoid fishes. Exact- 

 ly like the numberless bonebeds along Dead 

 Dodge Canyon. What delighted me most of all 

 was discovering the nearly complete pelvic 

 girdle, including the footed ischia, proving that 

 these bones belonged to a crested dinosaur like 

 the one we found on Ked Deer river and was call- 

 ed StepJianosaurus by Lambe and Corythosaur-
