This is a beautiful specimen of Phacops speculator. This trilobite is from the Devonian of Morocco. This large specimen is extremely inflated and wonderfully articulated. The trilobite exhibits exquisite detail. The individual lenses of the eyes are easily seen. The granulose surface of the exoskeleton is quite evident. The trilobite has fantastic natural color and superb contrast with the lighter-colored matrix. It is almost perfectly centered on the rounded block of matrix. This is a terrific Phacops speculator from Morocco.
