Phacops rana Trilobite aka Eldredgeops

Here is one of the largest Phacops rana trilobite molts I have found. It is about 4 cm wide. It is quite broken up and has piece of bryozoan stem sticking through it.

It was found in Clark County, Indiana (across the Ohio River from Louisville, Kentucky) in the North Vernon Formation. This creature existed in the Devonian Period.
