Description
A single valve of a bivalve mollusk, likely a clam, exhibiting an off-white to cream coloration. The shell is characterized by prominent, regularly spaced concentric growth lines or ribs across its surface. Its shape is broadly ovate to subtrigonal, with a rounded anterior and posterior margin and a slightly pointed umbo. The specimen appears to be well-preserved, showing the typical morphology of a venerid clam.
