We entered the field at Drumheller, Alberta, the center now 

 of a rich coal field with extensive mines. The chasm of the 

 Red Deer river is about two miles wide, nearly five hundred 

 feet deep, with exposed strata on each side of the river. Here 

 is a brackish-water deposit of clays and fine sand, with coal 

 beds of enormous areal extent — simply inexhaustible. The 

 farmers are allowed to mine all the coal they need for their own 

 use, on the payment of a small royalty. 



The next season I moved down the river eighty miles from 

 Drumheller to the fresh-water deposit of the Belly river series, 

 which is of the same age as the Pierre, which lies immediately 

 above, showing that in this region the land had been elevated 

 above the Pierre ocean. We found Pierre plesiosaurs in the 

 Belly river beds, showing that the rivers and bayous emptied 

 into the sea near by. The plesiosaurs swam inland and often 

 left their bones to mingle with the land and swamp dinosaurs. 



Doctor Brock, the director of the Geological Survey, and 

 deputy minister, who employed me, says in his report for 1912.^ 



"Perhaps the most notable additions to the collections, at all events 

 the most striking, have been the dinosaurs collected the past season by 

 Mr. Charles H. Sternberg-, perhaps the best-known collector in the world, 

 whose specimens are to be found in all the great museums. The services 

 of Mr. Sternberg and his son Charles have been secured, and he was 

 sent on a well-equipped expedition to collect vertebrate remains from the 

 rich bone beds discovered by the Geological Survey twenty-five years ago 

 in the Red Deer river, Alberta. This expedition was fortunate enough to 

 discover two complete specimens of the large duck-billed dinosaurs. A 

 well-equipped vertebrate paleontological laboratory has been installed, 

 and in it one of the specimens, thirty-two feet long, is being mounted by 

 Mr. Sternberg and his son, as a panel mount." 



In his report for 1913- Doctor Brock says : 



"The most notable additions have, however, been made in vertebrate 

 paleontology. Mr. C. H. Sternberg, assisted by his sons, has succeeded 

 in recovering from the Edmonton and Belly river beds of the Red Deer 

 river a priceless collection of the monsters that formerly inhabited this 

 region. The material is rich, not only in new species, but in new genera, 

 and many of the specimens ai-e, therefore, type specimens. Several strik- 

 ing mounts of these animals have been prepared and are on exhibition, 

 and good progress has been made on others, which will prove of excep- 

 tional interest and value." 



Among the wonderful dinosaurs of the Belly river formation, 

 I believe the most unique is Lambe's Styracosaurus albertensis.
