A single, fragmented seashell rests on a plain, off-white, flat surface

A single, fragmented seashell rests on a plain, off-white, flat surface. The shell fragment measures approximately 6 cm across its widest point and exhibits a rough, fan-shaped morphology with pronounced, layered ridges along its curved edge. Its coloration is mottled, predominantly light brown and beige, with a distinct greenish tint on its interior surface and pinkish-purple encrustations or discoloration along its ridged exterior. The shell shows signs of wear and breakage, particularly at its narrower, posterior end. Several fine, dark, hair-like fibers are visible on the surface immediately surrounding the shell. The background is uniformly light, indicating an indoor or controlled setting. This item is associated with the coastal region of Palma de Mallorca, Spain.
