The dinosaur remains furnish the most conclusive evidence of the age 
of the beds in which they were found as being equivalent to the Lance, as 
that formation is known in Wyoming, Montana, and the Dakotas. 
This is shown by the presence of Thescelosaurus neglectus Gilmore and 
Triceratops? prorsus Marsh, both typical Lance forms and unknown else- 
where. 
A badrosaurian reptile, probably a new species, which clearly has its 
closest affinities with the Lance, Thespesius annectens (Marsh), and the 
presence of the genus Ornithomimus, furnish corroborative evidence of 
the Lance facies of this fauna. 
This brief review of the above faunal list of the vertebrate remains 
found in southern Saskatchewan, shows that though only a few of its 
recognized members are confined exclusively to the Lance formation, the 
faunal list as a whole may be considered typically representative of that 
formation.
