Description
A bivalve seashell, likely a single valve, displaying an ovate to subtrigonal shape with distinct, fine concentric growth lines across its surface. The shell is moderately inflated and equivalve, with the umbo slightly anterior to the midline. The coloration is predominantly off-white to light grey, with subtle yellowish-brown bands or blotches, particularly noticeable towards the umbonal region. A small, white, calcified tube, possibly from a serpulid worm, is attached to the shell's exterior. The specimen appears to be well-preserved, showcasing the typical morphology of the species.
