In the Red Deer river district the upper beds of the series are represented, with 

 probably the tipper part of the lower beds. They consist mainly of, from about 200 to 

 400 feet of alternating soft, light gray, clayey sandstones and grayish and dark clays with 

 thin beds of ironstone and layers of ironstone nodules. Thick beds of yellowish sand- 

 stone also occur near the base. These yellowish sandstones appear to be at about the 

 dividing line between the upper and lower portions of the series. 



The Belly River series is correlated by Dr. Dawson* with the Judith River series of 

 the Missouri. 



One of the first reports, if not the first, to appear on reptilian remains from western 

 Canada, was that of Professor E. D. Cope, which took the form of an appendix to Dr G-. 

 M. Dawson's " Report on the Geology and Resources of the forty-ninth parallel " issued in 

 18*75. Professor Cope here described certain dinosauriau, cheloniau and fish remains 

 from the " Fort Union group " of Milk river. 



Since then, reference has been made, from time to time in the reports of the Greolo- 

 gical Survey, to the discovery of reptilian remains in the Laramie and Belly River series, 

 at various localities in the north-west. Unfortunately, the collecting of such remains 

 has not been systematically undertaken and, except in one instance, no detailed report 

 has appeared on the occasional remains of reptiles brought from the west, that exception 

 being the description given by Professor Cope, f in 1892, of two skulls of Lcelaps incras- 

 satus, obtained in 1884 and 1889, by Mr. .T.B. Tyrrell and Mr. T. C. "Weston, respectively, 

 on Red Deer river, from rocks of the Edmonton series. 



One of the chief difiiculties, encountered in studying the remains of the dinosaurs 

 and other reptiles from the Red Deer river district, arises from the fact that the bones are 

 generally very much scattered, separate bones of different species occurring together, the 

 finding of a number of bones, of one individual, in their natural relative position to each 

 other being rare. 



As a rule the bones are well preserved but very fragile, so that the greatest care is 

 requisite, and special precautions necessary, before their removal can be attempted.
