Atrypida

Atrypida is an extinct order of rhynchonelliform brachiopods. They first appeared in middle Ordovician and survived the Ordovician-Silurian extinction, becoming the dominant brachiopods of the Silurian alongside the order Pentamerida.[3][4] They would survive into the Late Devonian before going extinct at the end of the Frasnian (Late Devonian).[2]
