Abstract
O. C. Marsh gave the name Ceratops beds to certain strata in the upper Cretaceous of Wyoming, Montana, and Colorado, con taining the remains of horned Dinosaurs (Ceratopsidm) and many other reptilian and mammalian forms.Of these beds, those in the northeastern portion of Converse county, Wyoming, are best known and have been most thoroughly explored.Fully ninety pel' cent. of all the vertebrate fossils described by Prof. Marsh from the Ceratops beds were found in this region.This fact is sufficient to warrant a more detailed description of the stratigraphical and geo~raph ical position of the beds, and of their geological and lithological characters, than has yet appeared.Not only has this region pl'Oved especially rich in vertebrate fossils, but the Ceratops beds seem to have attained a greater development here than has been noticed elsewhere.Since the present border of the beds is nearly that of the eastern shore of the fresh-waters in which they were deposited, and erosion has exposed many continnous sections in them down through the underlying Fox Hills sandstones and into the Ft.Pierre shales, this region offers exceptional advantages for determining the position of the Ceratops beds and for establishing their age upon stratigraphical as well as paleontological evidence.
