Beautiful, 3.25" Crotalocephalina Trilobite - Atchana, Morocco

This is an absolutely gorgeous, 3.25" specimen on Crotalocephalina gibbus from Atchana, Morocco. The shell preservation and coloration on this particular specimen is fantastic. Whiles this is a pretty common trilobite it's rare to see ones that look this nice. The rock has been removed from underneath the tail spines leaving hem free standing. There is a partial of a second crotalocephalina on the edge of the rock.

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