Tlie original description of " Puerco marls. " Type locality, 

 head of Puerco River. Gives section (p. 96) showing relation 

 of Puerco and other beds in that vicinity. No mammalian

1881.1. Mammalia of the lower Eocene beds : Am. Natural- 

 ist, vol. 15, pp. 337-338, April, 1881. 



The first mammals are described, but they were not l^nown 

 definitely at that time to be from the Puerco formation.

Contains a general r63Um6 of the Wasatch. The deposits of 

 the Bridger and W'ashaliie Basins and small area on White 

 River in the Uinta Basin considered contemporary. Table 

 of formations in this worli places Puerco as "post-Cretaceous," 

 but in the text the author places it definitely in the Eocene. 



1885.2. The relations of the Puerco and Laramie deposits: 



Am. Naturalist, vol. 19, pp. 985-986, October, 

 1885. 



states that the thickness of the beds near the type locality is 

 850 feet. The author points out the distinctions from Laramie 

 but considers the possibility of "post-Cretaceous" age.
