Description
A single valve of a bivalve mollusk, exhibiting an ovate to subtrigonal shape. The shell surface is characterized by prominent concentric growth lines and a distinctive pattern of reddish-brown bands alternating with cream or off-white coloration. A small, circular bore hole is visible on the shell, indicative of predation, likely by a carnivorous gastropod.
