The fauna contained in coquina from the Cape Hatteras region, North Carolina, includes sponges, coral, echinoderms, bryozoans, polychaetes, barnacles, many gastropods, a scaphopod, and many pelecypods. Its species composition is listed, analyzed geographically, and discussed. Among the 73 named species, Aequipecten gibbus, Mercenaria mercenaria, Spisula solidissima , and pelecypods in general were most abundant. Although many southern species of warm-water affinities were found, several northern species of cold-water affinities were present, some of which could be attributed to a previous or subsequent geologic period. Both estuarine and oceanic assemblages were represented. Most of this fauna has been regarded as belonging to the Pamlico Formation, dating from the last interglacial (Sangamon) age (late Pleistocene).
