carnivorous dinosaurs and supported great caudo-abdominal muscles. In 

 life this animal was about thirty-two feet in length and stood between fif- 

 teen and seventeen feet in height when erect. These measurements refer 

 to the skeleton only and do not include the erectal skin portion of the crest 

 which probably added considerable to the height during excitement when 

 the dinosaur must have been a most imposing creature. 



Like Trachodon it was an herb-eater and without means of defense from 

 the contemporary flesh-eating Albcrtosaurus except in its power of swimming 

 away from danger. Great numbers of these creatures lived in the pre- 

 historic coastal marshes. In a single quarry — and there are many such 

 quarries on the Red Deer River — bones of several hundred individuals 

 mostly of this kind have been washed out of the bank. 



The expedition to Alberta last summer secured a carload of fossils 

 several of which are new to science. One of the prize specimens is an un- 

 usually complete skeleton of another new dinosaur coining from an older 

 formation and probably ancestral to Saurolophus. In this new skeleton 

 the skin impression is preserved more or less completely on one side. When 

 prepared it will be exhibited as a double-faced panel, one side showing the 

 skin, the opposite side showing the bones and their muscle attachments.
