Brachiopod shells are an obvious predator deterrent; however, most species have relatively thin shells and the fossil record suggests that predators may be able to bore through them, if rarely. It appears that the flesh of brachiopods is unpalatable and they therefore are not generally subject to predation, particularly in the presence of ...Brachiopods are benthic (bottom dwelling), marine (ocean), bivalves (having two shells).

Maine's fossil record covers a vast span of time. Fossils preserved in bedrock date from 500 to 360 million years ago.
