Lamp Shells: Phylum Brachiopoda. Brachiopods are shelled invertebrate that look somewhat like bivalved molluscs.

Like clams, the brachiopod lives in a shell consisting of two hinged valves, but ...

Bivalves and brachiopods are both sessile filter feeders, sitting on the seafloor and filtering water for food and oxygen. Their abundance reversed at the end of the Permian, when the greatest of all known mass extinctions eliminated more than 95 percent of Earth's ocean species.

Brachiopods are the most abundant fossils in Wisconsin. Most people are not familiar with living brachiopods because modern species inhabit extremely deep regions of the world’s oceans, and their shells are rarely found on modern seashores.
