Pseudocardium densatum

Bivalvia - Cardiida - Mactridae

Taxonomy
Mulinia densata was named by Conrad (1856). It is a 3D body fossil. Its type locality is Foxen Canyon (USGS 15011) #33 (Woodring & Bramlette, 1950), which is in a Messinian/Zanclean coastal sandstone in the Sisquoc Formation of California.

It was recombined as Pseudocardium densatum by Moore (2003).
