Bargain, 2.4" Hollardops Trilobite - Foum Zguid, Morocco
This is a 2.4" long, chocolate brown Hollardops trilobite quarried near Foum Zguid, Morocco. The preparation is pretty rough, leaving lots of scratches on the shell, but you can still see clear eye facets in both eyes and there is no 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.
