Description

The image displays two specimens of a Pheasant Shell, identified as Phasianella ventricosa. These are marine gastropod shells, characterized by their turbinate to conical shape and smooth, glossy surface. One shell is largely intact, showing a wide, ovate aperture and a somewhat eroded apex. The other shell appears to be a fragment or a more heavily damaged specimen, showing the interior of the aperture. The shells exhibit mottled patterns of cream, grey, and reddish-brown, though the colors appear somewhat faded. They are presented alongside collection labels providing taxonomic and locality information.
