(Scale bar is 1 cm)

This is one of many species of spatangoid echinoids in the Ocala Limestone of Georgia.

The species known only from the upper part of the Ocala Limestone, and so is useful in correlation.

Because these animals burrowed into the sediment, their shells included specific adaptations for moving themselves, and also for moving food, waste, oxygen, and carbon dioxide into the burrow. The shell form of this species suggests that it could have inhabited either sand or mud bottoms, and it is usually found in the latter type of sediment.
