3" Spiny Quadrops Trilobite With Paralejurus - Ofaten, Morocco

Spiny Quadrops Trilobite With Paralejurus - Ofaten, Morocco #243639

This is a fantastic association of a spiny Quadrops trilobite along with a Paralejurus. It was quarried from the El Otfal Formation near Ofaten, Morocco. This spectacular piece is well prepared. Nearly all of the spines on the Quadrops have some restoration at their base where they were reattached.

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.
