Comments

This specimen and dozens like it were collected from matrix material deposited in the waters of the Chesapeake Bay by a landslide. It is one of only a few species that consistently survived intact in the matrix samples I collected. Most specimens were single, unbroken valves, but one did have both valves together and intact. This specimen was donated to the Delaware Museum of Natural History.
