This genus first appeared in the Permian period of China, Italy, and Pakistan . " Anomia " species are common in both tropical and temperate oceans and live primarily attached to rock or other shells via a calcified byssus that extends through the lower valve . " Anomia " shells tend to take on the surface shape of what they are attached to; thus if an " Anomia " is attached to a scallop shell, the shell of the " Anomia " will also show ribbing.
