Cyclocardia granulata Bivalve SITE LOCATION: James City Formation, Beaufort Co., North Carolina, USA TIME PERIOD: Pleistocene age (2,588,000 to 11,700 years ago) Data: Cyclocardia is a genus of molluscs in the family Carditidae. The related genus Vimentum is sometimes included here. Carditidae is a family of marine bivalve clams of the order Carditoida, which was long included in the Veneroida. They are the type taxon of the superfamily Carditoidea. Delimitation of this family versus the closely related Condylocardiidae is somewhat problematic. Kingdom: Animalia Phylum: Mollusca Class: Bivalvia Order: Carditoida Family: Carditidae Genus: Cyclocardia Species: granulata

Cyclocardia granulata Bivalve SITE LOCATION: Probably James City Formation; found Aurora, North Carolina, USA TIME PERIOD: Lower Pleistocene (2.588 ± 0.005 and 0.781 ± 0.005 million years ago) Data: Cyclocardia is a genus of molluscs in the family Carditidae. Original Description (from Say, 1824, p. 142): "Suborbicular, with about twenty-five convex ribs, and wrinkled across; inner margin crenate. Description. Beaks nearly central, a little prominent, curved backward: ribs granulated on the umbones, and transversely wrinkled near the base, convex: apices somewhat prominent beyond the general curve of the shell: inner margin and edge crenate: cardinal teeth two. Length from the apex to the base four-fifths of an inch, breadth nearly the same. Rather proportionally longer than the decussata, and more oblique."
