Aesthetic Association of Four Trilobites From Ofaten, Morocco
This is an aesthetically presented, natural association of four trilobites (three different species) collected near Ofaten, Morocco. There is a 2.1" long Hollardops mesocristata, along with a pair of Morocops and a Cornuproetus. The surrounding limestone has been shaped to create an impressive, free-standing display piece. Excellent shell detail including eye facet preservation on all of the trilobites.
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.
