Trilobites were associated with the Paleozoic era, from the Cambrian to the Permian.
Trilobites were rapidly evolving and widespread marine organisms that spanned a number of geologic time periods. Certain types of trilobites only appeared in specific segments of geologic time; therefore, when one of these trilobites is found, you can be certain that the rock layer it is found in is of a certain geologic age.
Trilobite.
The trilobite.
Ohio's state fossil is the trilobite.
Paleontologists, stratigraphers, and geochronologists worked with geologists to develop the geologic time scale. Paleontologists studied fossil evidence, stratigraphers looked at the layers of rock formations, and geochronologists used radiometric dating techniques to determine the age of rocks and fossils.

The Pennsylvania state fossil is the Phacops rana, a kind of trilobite.
No. Trilobite fossils are much older.
