What did a phacops eat?

Phacops, a genus of extinct trilobites, were primarily scavengers and likely fed on detritus, small organisms, and organic matter on the seafloor. Their compound eyes suggest they may have also hunted small prey, such as soft-bodied invertebrates. They used their specialized mouthparts to scrape or grind food, contributing to their role in the marine ecosystem during the Paleozoic era.
