1.85" Protolenus Trilobite Molt With Pos/Neg - Tinjdad, Morocco

This is an 1.85" long specimen of the Middle Cambrian trilobite Protolenus (Protolenus) densigranulatus. The bright orange coloration is natural and due to the oxidization of iron pyrite. This specimen is a molt. Comes with both the positive and negative impressions.

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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
