1.85" Crotalocephalus Trilobite With Axial Nodes - Jorf, Morocco

This is a 1.85" long Crotalocephalus trilobite (not to be confused with Crotacephalina) from Jorf, Morocco. There appears to be at least two species from this locality, one of which (this one) has very distinctive nodes on each axial ring. There also appear to be a healed injury to two of the pleural tips on the left hand side of the body.

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.
