1.2" Detailed Reedops Trilobite - Atchana, Morocco
This is a 1.2" long, Reedops trilobite collected near Atchana, Morocco. It has a lot of surface detail including, visible, preserved eye facets. It's been prepared to remove the surrounding limestone so that it looks like it's ready to crawl off 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 currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
