Abstract

New collections of Pottsvillean goniatites from the eastern Kentucky coalfield area show a close resemblance to those of the southern Mid-continent. The most important form for age assignment is an upper Morrowan element, Diabloceras neumeieri Quinn and Carr, 1963. Gastrioceras occidentale (Miller and Faber, 1892), the most common species in the Kentucky fauna, is comparable to forms from Arkansas and Oklahoma. Also, Dimorphoceratoides campbellae n. gen. et sp. can be related to a known phylogenetic sequence elsewhere.
