Nemocardium (Nemocardium) diversum

Bivalvia - Cardiida - Cardiidae

Taxonomy
Cardium diversum was named by Conrad (1848) [DISTRIBUTION: Early Olgocene; Gulf Coastal Plain.]. Its type specimen is ANSP 30651, a shell, and it is a 3D body fossil. Its type locality is Vicksburg, which is in a Rupelian marine marl in the Byram Marl Formation of Mississippi.

It was recombined as Protocardia diversa by Gabb (1861); it was recombined as Cardium (Protocardium) diversum by de Gregorio (1890); it was recombined as Protocardium diversa by Cooke (1923); it was recombined as Nemocardium diversum by Mansfield (1940) and Gardner (1945); it was recombined as Nemocardium (Nemocardium) diversum by Dockery (1982).
