Trilobite fossil age.

Trilobites are a common fossil in many of the early to middle Paleozoic rocks of central Pennsylvania. These rocks range in age from 541 to 359 million years old. Complete fossil specimens are rare because a trilobite’s rigid outer skeletal segments were joined by flexible organic connections that decayed on the death of the animal.Trilobite.
