Phacops is a genus of trilobites in the order Phacopida, family Phacopidae, that lived in Europe, northwestern Africa, North and South America and China from the Late Ordovician until the very end of the Devonian,[2] with a broader time range described from the Late Ordovician.[3] It was a rounded animal, with a globose head and large eyes, and probably fed on detritus.[4] Phacops is often found rolled up ("volvation"), a biological defense mechanism that is widespread among smaller trilobites but further perfected in this genus.[4]
