OX REPTILIAN REMAINS FROM THE CRETACEOUS 

 OF NORTH-WESTERN CANADA. 



By Lawrence M. Lambf, K.G.S. 



The collection of fossils made by the writer during the 

 summers of 1897 and 1898 from the Cretaceous rocks of the Red 

 Deer River, in the Districts of Alberta and Assiniboia, consist 

 principally of dinosaurian remains, but include a'so the remains 

 of turtles and crocodiles as well as a few fish vertebrse and 

 scales, leaves and silicified wood.* \ 



The rocks exposed along the Red Deer River are those of 

 the Belly River, Pierre and Laramie formations, but by far the 

 larger number of fossils were secured from the Belly River beds 

 which are especially interesting as representing a terrestrial fauna 

 separated from that of the Laramie by the thick marine beds of 

 the Pierre. 



Taking into consideration the reptilian remains only, it is 

 found that they represent the three orders Cliclonia, Crocodilia 

 and Dinosaiiria. 



I. The following provisional enumeration may be made of 

 the fossils from the Belly River formation : — 



I. Chelonia — 



Plastomenus coalescens, Cope. Parts of the dorsal and 

 ventral shields.
