Niobara formation.
The Niobrara Formation, commonly referred to as the Niobrara Shale, but also known as the Niobrara Chalk, was deposited in the Western Interior Seaway in the middle of North America during late Cretaceous Age. ( 145.5 - 65.5 million years ago) This inland sea divided the continent of North America during much of the Cretaceous.
Niobrara Formation. According to Hattin (1982), Moore and Hays (1917) were the first to regard the Kansas Niobrara as a formation, and the first to give member status to the currently recognized divisions; the Fort Hays Limestone Member and the Smoky Hill Chalk Member.
