Brachiopods are some of the oldest and, at one time, most populous invertebrates on the planet. According to the available fossil records, brachiopods first appeared over 500 million years ago, and shortly after became the most common shelled creature in the sea. They remained dominant until the Permian mass extinction, which occurred around 250 million years ago. While they managed to hold on, brachiopods have yet to return to their former glory.
