Occurrence of the chimaeroid Ischyodus bifurcatus Case in the Cusseta Formation (Upper Cretaceous, Campanian) of western Georgia and its distribution

We described a Late Cretaceous fish fauna from the Campanian-age Blufftown Formation in western Georgia (Case and Schwimmer, 1988), including 15 selachian taxa and 8 osteichthyans; however, at that time no chimaeras had been found in the region. A well-preserved specimen of Ischyodus bifurcatus Case, 1978, was subsequently collected from the same general locality described in the above study, but in the immediately superjacent Cusseta Formation. This is a note of the new occurrence of this fish and a summary of its known geographic and stratigraphic distribution (Appendix).
