Abstract/Description: Ordovician. Brookville Formation. During the Ordovician, brachiopods were the dominant shellfish and occurred abundantly on the seafloor globally. Although you won't find brachiopods at the beaches in North America today, they are still alive and most commonly living in colder ocean waters off the coast of the Pacific Northwest, Alaska, New Zealand, Antarctica, and other cooler oceans of the world.
