Pair Of Early Cambrian Trilobites (Perrector) - Tazemmourt, Morocco

This is an elegant pair of Perrector falloti trilobites from from Tazemmourt, Morocco. Perrector is one of the earliest trilobites in the Cambrian. The larger of the two specimens is 2.8" long (huge for the species) and the smaller is 1.35". They have been nicely prepared to bring the fossils out in high relief against the rock.

The genus Perrector is synonymous with Richterops and Resserops. While these other two names are more frequently used when referring to this species Perrector is probably the most technically correct.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
