Flying Crotalocephalina & Paralejurus Trilobite Association

This is a stunning, natural association of two different genus of trilobite in the same rock. There is a 2.6" long Crotalocephalina sp., a 2.9" long Paralejurus. Both of them have been prepared, so that most of the rock has been removed from underneath them, creating a spectacular display. No significant restoration.

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.
