Estuarine and lagoonal backbarrier deposits in the Neuse River area of the NC Coastal Plain are here named the Beard Creek Member of the Flanner Beach Formation, following the informal usage of Mixon and Pilkey (1976). It consists of fine to medium sand and muddy sand containing mollusks and minor silt and clay interbeds. Gradationally and conformably overlies the Smith Gut Member of the Flanner Beach; intertongues to the east with the Arapahoe Sand Member of the Flanner Beach. Thickness is 4 m at type locality. Age is middle Pleistocene.
