Eutrephoceras (Nautiloidea) from the Paleocene Beaufort Formation of North Carolina

Abstract

Well preserved specimens of Eutrephoceras sloani Reeside, collected from a recently exposed outcrop of the Paleocene Beaufort Formation in east-central North Carolina, represent the first reported Paleocene nautiloids from Coastal Plain strata of North Carolina. This species was formerly known only from the Paleocene Black Mingo Formation in eastern South Carolina, about 280 km southwest of the North Carolina Paleocene outcrops. The North Carolina specimens allow clarification and elaboration of Reeside's original description.
