378 B. BROWN CRETACEOUS-EOCENE CORRELATION IN NEW MEXICO 



River age, and the plants are said to have very little affinity with the 

 flora of the Lance or Fort Union. 



The vertebrates, on the other hand, are of Judith Eiver age and are 

 beyoiid question closely related and in most genera and species directly 

 ancestral to those of the Edmonton and Lance. 



Many of the genera and species of dinosaurs founded by Leidy, Cope, 

 and Marsh were based on material inadequate for the present standard of 

 classification. The characters assigned to many species by these early 

 investigators are now known to have only generic or family value. For 

 this reason it seems inadvisable to append the long list of species of each 

 formation.
