Amalda australis

Amalda australis, common name the southern olive, is a medium-sized sea snail, a gastropod mollusc of the family Ancillariidae. These predatory snails live in the inter-tidal sand, an environment that lends itself to high probability of fossilization. Amalda australis fossils date back to the Pliocene and reveal morphological stasis.
