The “sand Dollars” are flattened Sea Urchins. They are Echinoderms related to starfish and modern sea urchins. They lived in shallow water environments and lagoons below the tide line buried in the sand or mud. When alive they were covered by spines. They are basically circular in shape and various species could be very thick. This species is on the thin side only several millimeters thick.

They fed on algae and diatoms and small copepods living at the bottom of the shallow water beach areas.
