Description
A robust bivalve mollusk shell, commonly known as the Columbia Venus clam, characterized by its oval to subquadrate shape and distinctive cancellate sculpture. The shell surface displays intersecting concentric growth ridges and radial ribs, creating a textured, cross-hatched pattern. It is typically off-white to grayish-white, with the sculpture often appearing more pronounced and lighter in color.
