A New Species of Bukryaster from the Upper Cretaceous of Southeast Oklahoma
AbstractA new species of the calcareous nannofossil Bukryaster Prins, 1970, occurs in the Ozan Formation of southeast Oklahoma. The Ozan Formation is a member of the Cretaceous Gulfian Series, considered Campanian in age; it consists of marly shales in the lower layers and chalks in the upper layers. The formation has been found to contain a diverse assemblage of marine and terrestrial fossils with cephalopods, oysters, and Inoceramus common in several layers. In addition to the megafossils, the Ozan contains a wide variety of ostracods, hystrichosphaerids, acritarchs, dinoflagellates, spores and pollen, and both micro-and megaforaminifera. The most common fossils however, are the coccoliths and associated nannofossils.
