In rocks containing longer fragmentary shells (Pl. 5B) such particles invariably make up less than 25 percent of etched limestone surfaces. Pelecypod valves are found on the surfaces of these limestones; therefore, contained shell fragments are probably those of mollusks, and the limestones are referred to as molluscan limestones.A blog about fossils from around the world.

I did some reading and found some theories on why some think most of the abundant brachiopods died off (95% of species) while the pelecypods prospered so well.
