 RESTORATION OF MONOCEONIUS MADE UNDER THE DIRECTION OF PROF. E. D. COPE, 



BY CHARLES R. KNIGHT 



This is one of the primitive horned dinosaurs, the Ceratopsia, in which the horn over the 

 nose was largest. In the later members of the family the horns above the eyes are largest 

 (see page 427). Its remains are quite abundant in the Belly River beds. 



more different kinds, for reptilian life is 

 now on the wane. 



Rarely does a season pass without sev- 

 eral new genera being- brought to light, 

 and this possibility of discovery of the 

 new and unknown adds zest to an already 

 fascinating field of research. Any pros- 

 pect may reveal some new creature of 

 bizarre form, and we are constantly find- 

 ing skeletons of animals known before by 

 parts only. 



The Edmonton formation has been es- 

 pecially interesting, for at least two-thirds 

 of the species discovered in rocks of that 

 age are new to science. 



By the time we had reached Tolman, 

 where a road crosses the river, our flat- 

 boat, piled high with boxes of fossil ani- 

 mals, had become a veritable fossil ark. 

 This was in the latter part of September ; 

 thin ice was forming on the river and it 

 became too cold to do further effective 

 collecting. The boat was then beached 

 for the winter and the collection shipped 

 back to the Museum. 



Each summer work has been continued 

 from the point at which it ceased the year 

 before and the search has been carried 

 on thoroughly. 



Elsewhere complete dinosaur skeletons 

 are rare, but in this part of Alberta they 

 are not uncommon. In no other part of 

 the world have so many Cretaceous dino- 

 saur skeletons been brought to light. One 

 American Museum Expedition collected 

 eight skeletons from a limited area ex- 

 posed along three miles of the Red Deer 

 River. 



CAMP EIFE WHIEE ON THE HUNT 



Searching for prehistoric animals by 

 boat is even more interesting than similar 

 work in the arid "Bad Lands" of the 

 plains. Those who have husbanded 

 drinking water on the desert through long 

 hot summers keenly appreciate a river 

 of snow water. 



Pike, pickerel, and sturgeon are caught 

 in the Red Deer, and the persistent angler 

 never fails to land a few "gold-eyes," a
