Two Associated Crotalocephalina Trilobites - Foum Zguid, Morocco

This is a pair of Crotalocephalina sp. trilobites quarried from Foum Zguid, Morocco. They are both partially enrolled but would be about 2.5" long if outstretched. Nice preparation and comes with a display stand.

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.
