Large Enrolled Phacops Trilobite In Matrix

This is a well preserved and very detailed Phacops trilobite from Mrakeb, Morocco. It's is enrolled in a defensive position and would have been over 3 inches long if outstretched. It's still embedded in the original matrix and the shell detail is amazing with all of the eye facets and pustules covering it's shell preserved. There is some very minor shell restoration near the back of it's head.
