Crotalocephalina, Paralejurus & Reedops Trilobite Association

This is a fantastic, natural association of three different types of trilobites from Atchana, Morocco. The largest trilobite is a Crotalocephalina which would be about 3" long if outstretched. It is right next to a 2.3" long (if outstretched) Paralejurus and a smaller, enrolled Reedops.

Getting three species of trilobites in close association like this is quite unique. The piece has been expertly prepared to create a very aesthetic display.

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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
