Introduction- 



For the American Museum I have been continuously engaged since 

 June, 1900, in the exploration of the geology, flora, and fauna of three 

 great formations which in their animal and plant life bridge over the 

 passage from Cretaceous to Eocene time, as determined by comparison 

 with the life of the same epochs in Europe. I propose to compare these 

 formations with each other and with the typical Lance Creek formation 

 of Wyoming. These formations are : 



Years 



Hell Creek formation of northern Montana 1902-1909
