Nuculana (Saccella) merriami

Bivalvia - Nuculanida - Nuculanidae

Taxonomy

Leda merriami was named by Dickerson (1917). Its type specimen is CAS 381 and is a 3D body fossil. Its type locality is CAS loc. 181, Cowlitz River, 4mi E. of Vader, which is in an Eocene coastal sandstone/conglomerate in Washington.

It was recombined as Nuculana merriami by Effinger (1938), Durham (1944); it was recombined as Nuculana (Saccella) merriami by Moore (1983).
