Idaho and western Wyoming and gives 1500 feet of Jura, the upper 700 feet gray 

 shales and green sandstone ; the lower 800 feet of limestone and shale, below 

 which he describes 4000 feet of Trias chiefly red with some calcareous beds with 

 some fossils in the lower part. 



In Hayden's Report, 1878, Dr. White has a special Report on Palaeontology 

 published in 1880, including two plates of Jurassic and two plates of Triassic 

 fossils. In this he speaks of the Jurassic of southern Utah and says the Triassic 

 is not recognized by fossils east of the Rocky Mountains. 



In Palseontology of California, Meek devotes eleven pages and two plates to 

 Jurassic fossils, and Gabb has sixteen pages and four plates of Triassic. 



In Jones' Report on Northwestern Wyoming and Yellowstone Park, 1875, 

 Prof. Comstock names the red beds of Deep Creek, Wind River Mountains, and 

 calls them Triassic, but says they are devoid of fossils. Over them he found 

 1000 feet of Jurassic including eight species of fossils. 



In Ludlow's Report of Reconnoissance of the Yellowstone Park, 1875, three 

 specico of Jurassic fossils are figured and described by R. P. Whitfield. These 

 were obtained from Bridger Mountains, Montana, on East Gallatin River. Mr. 

 E. S. Dana in the Geological Report mentions finding seven species of fossils. In 

 Report on Palaeontology of the Black Hills, 1880, Prof. R. P. Whitfield has four 

 plates of Jurassic fossils, the specimens obtained from the Black Hills and Big 

 Horn Mountains. In Bulletin U. S. Geological Survey, 1876, Vol. II, No. 3, 

 Hayden gives a section at head waters of the Missouri and Yellowstone showing 

 Jurassic overlying the Carboniferous of Gallatin River. 



In Bulletin, Vol. Ill, No. 3, 1877, White speaks of the Jurassic of the 

 Rocky Mountains. 



King in the Geological Report of the 40th Parallel devotes forty-six pages to 

 the Jurassic and Triassic. He refers to their occurrence on Big Thompson' 

 River, on the Chugwater- and Brush Creeks. Near the hne of Colorado and 

 Wyoming, southwest of Laramie, Mr. King gives [200 feet of red beds. King 

 mentions the occurrence of Trias in the Uinta range, on Yampa plateau, on Du 

 Chesne Creek. He speaks of the occurrence of Pentacrinus Astericus near the 

 base of the Jura. In the Western Humboldt range he speaks of a limestone with 

 distinct Jurassic fossils which have been described by Meek and Gabb. King 

 estimates the Humboldt Jurassic to be 15 to 17000 feet thick. King enumerates 

 four species of Jurassic fossils from Como Station, Union Pacific Railway; five 

 species from Rawlings Peak in beds below the cretaceous Dakotah. In the Uinta 

 Range a number of fossils have been obtained ''rom the Flaming Gorge. King 

 in Vol. IV, 40th Parallel Survey, devotes two plates to Triassic fossils and one 

 to Jurassic. The fossils are identified and described by R. P. Whitfield, and 

 are from Wyoming, Utah and Nevada, chiefly from Augusta Mountains, Nevada, 

 and Flaming Gorge, Uinta Range. The Triassic from the Wahsatch and Hum- 

 boldt are identified by Meek. 



In Vol. II, of 40th Parallel Survey by Emmons and Hague, considerable 

 space is devoted to the discussion of the Jurassic including strata of the Uinta
