Pair Of Well Preserved Austerops Trilobite - Ofaten, Morocco
This is a pair of well preserved and prepared Austerops trilobites from Ofaten, Morocco. The larger of the two individuals is about 2.6" long. There is only about 1-2% shell restoration on this piece.
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.
