Westward extension of Seboyeta Bay, late Cretaceous (Cenomanian) of west-central New Mexico
— Orin J. Anderson and Spencer G. Lucas
A molluscan fossil assemblage dominated by Exogyra levis Stephenson and Granocardium enstromi (Bergquist) is present in the upper part of the Dakota Sandstone along Cottonwood Canyon in extreme western Catron County. These fossils indicate correlation with the middle Cenomanian Paguate Tongue of the Dakota Sandstone. They thus extend the Seboyeta bay in which the Paguate was deposited 40 km to the west-southwest.
