The Pierre Shale
Shale
/pɪər ʃeɪl/ is a geologic formation or series in the Upper Cretaceous
Cretaceous
which occurs east of the Rocky Mountains
Rocky Mountains
in the Great Plains, from Pembina Valley
Pembina Valley
in Canada[1] to New Mexico. The Pierre Shale
Shale
was described by Meek and Hayden in 1862 in the Proceedings of the Academy of Sciences (Philadelphia). They described it as a dark-gray shale, fossiliferous, with veins and seams of gypsum, and concretions of iron oxide. The Pierre Shale
Shale
is about 700 feet (210m) thick at the type locality. It overlies the Niobrara division and underlies the Fox Hills beds. It was named for an occurrence near Fort Pierre on the Missouri River
Missouri River
in South Dakota.[2] The Pierre Shale
Shale
is of marine origin and was deposited in the Western Interior Seaway. It is correlative with other marine shales that occur farther west, such as the Bearpaw Shale, Mancos Shale
Shale
and the Lewis Shale.[3] It correlates with the Lea Park Formation in central Alberta.[4] The Pierre is overlain by marginal marine deposits of the Fox Hills Formation.

Mineral resources[edit] The Pierre Shale
Shale
is the host formation for commercial oil deposits in the Florence and Canon City fields in Fremont County, Colorado, and the Boulder oil field in Boulder County, Colorado. More recently, natural gas has been extracted in the Raton Basin
Raton Basin
in southern Colorado. The shale formation is usually too impermeable for hydrocarbon extraction, but produces in areas where it is naturally fractured or fractured by artificial means. Paleofauna[edit] Hesperornithiformes[edit]
