Describes a new assemblage of Late Cretaceous dinosaur and reptile remains from Campanian and Maastrichtian deposits of eastern South Carolina (SC). Six of the 14 localities include new occurrences of theropod and hadrosaur dinosaurs, substantially increasing the known localities in the eastern U.S. that have produced dinosaur remains. The important but seldom-mentioned role that SC played in the early history of studies of North Amer. Cretaceous deposits and faunas is outlined, and the stratigraphic settings of 14 localities are analyzed. Of the 6 localities where dinosaur bones were found, two yielded the majority -- Stokes Quarry, Darlington County, in the mid-Campanian Coachman Formation; and the late Campanian Donoho Creek Formation at Kingstree, Williamsburg County.
