Description
A single valve of a bivalve mollusk, characterized by its elongated oval to somewhat triangular shape. The shell surface is smooth but marked by distinct, somewhat irregular concentric growth lines. The color ranges from a pale yellowish-cream to a richer orange-yellow, particularly noticeable near the umbo. Small dark specks, likely sand or debris, are visible on the surface. The shell appears robust and moderately thick.
