Description

A fossil seashell specimen of Polinices waipipiensis, a species of moon snail. The shell is globose to subglobose with a low spire and a smooth, somewhat eroded surface. The aperture is large and D-shaped. The shell material appears thick and is off-white to pale grey, with some darker specks, likely remnants of sediment or matrix. The overall shape is characteristic of the Naticidae family, adapted for burrowing in soft substrates.
