The conclusions at which he arrived from his extensive survey are given briefly as follows : (1) The only Tertiary formations which the author saw agree well in their geological types with the Eocene and Miocene beds of England and France ; (2) he found no secondary fossils in those rocks which have been called Upper Secondary and supposed to constitute a link between the Cretaceous and Tertiary formations.

Side 121 - The boundary line between the Cretaceous and Tertiary in the region of the Rocky Mountains has been much in dispute during the last few years, mainly in consequence of the uncertain geological bearings of the fossil plants found near this horizon. The accompanying invertebrate fossils have thrown little light on the question, which is essentially, whether the great Lignite series of the West is uppermost Cretaceous, or lowest Eocene. The evidence of the numerous vertebrate remains is, in my judgment,...

The climate and other physical conditions which were essential to the existence of the Dinosaurians of the Laramie period having evidently been continued into the Tertiary epochs that are represented by the Wasatch, Green...
