Lamelliconcha clarki

Bivalvia - Cardiida - Veneridae

Taxonomy
Pitaria clarki was named by Dickerson (1917). Its type specimen is CAS 393 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 Pitaria (Lamelliconcha) clarki by Tegland (1929), Effinger (1938) and Durham (1944); it was recombined as Pitar (Lamelliconcha) clarki by Clark and Anderson (1938) and Weaver (1942); it was recombined as Pitar clarki by Warren (1945); it was recombined as Lamelliconcha clarki by Hickman (2015) and Hendy (2020).
