2.2" Spiny Delocare (Saharops) Trilobite - Bou Lachrhal, Morocco
This is a spiny, 2.2" long Delocare (Saharops) bensaidi trilobite quarried at Bou Lachrhal, Morocco. There is about 5% shell restoration on this specimen and some of the tiny spines on the left-back side of the thorax have been restored.
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.
