He modeled different areas of the body separately, applying various densities to the different body sections to calculate his masses. His results suggested that the […]

This formation is exposed in northwest Kansas and southern Nebraska. Formations are sometimes divided into members, subsections of the formation based upon its rock type. The Niobrara Chalk has two members: the lower Fort Hays Limestone and the upper Smoky Hill Chalk. It is the […]
