Pair Of Black Reedops Trilobites - Aatchana, Morocco

This is a pair of naturally multi-toned trilobite (Reedops) fossils collected from the Lhandar Formation near Aatchana, Morocco. Both have excellent preservation and are nicely prepared. Only about 1-2% shell restoration along repaired cracks.

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.
