How did trilobites adapt

WebYet, despite their durability and obvious skill for adapting to ever-changing ecological conditions, it is now known that trilobites suffered a slow yet steady decline before eventually succumbing to a variety of environmental pressures. But why did this happen?

By the end of the Devonian (359 mya), the last of the Phacopidae went extinct, ending the order Phacopida.
