Description
A single, off-white valve of the bivalve *Dosinia prostrata*, characterized by its orbicular (nearly circular) and compressed shape. The shell exhibits numerous fine, regular concentric growth lines across its surface. The specimen shows two holes, likely from predation (e.g., by a naticid snail) or post-mortem damage, and appears somewhat beach-worn.
