Origin and stratigraphy of historic dinosaur quarries in the Upper Cretaceous Fruitland Formation of the Fossil Forest Research Natural Area, northwestern New Mexico
Adrian P. Hunt and Spencer G. Lucas

Abstract:

Five dinosaur quarries in the upper part of the Fruitland Formation in the Fossil Forest Research Natural Area were almost certainly collected by Charles H. Sternberg in the 1920s and probably yielded the holotypes of Pentaceratops sternbergi and Parasaurolophus cyrtocristatus, among other fossils. We divide the Fruitland Formation into two members, named here, a lower Neh-nah-ne-zad Member characterized by thick coal beds and an upper Fossil Forest Member that lacks such coal beds. The vertebrate fauna of the Fruitland Formation is mostly from the Fossil Forest Member.
