1.6" Scabriscutellum & Leonaspis Trilobite - Issoumour, Morocco

Scabriscutellum & Leonaspis Trilobite - Issoumour, Morocco #154810

This is a fantastic, natural association of a 1.6" Scabriscutellum right next to a 1.2" long Leonaspis. These trilobites from collected from the Comura layer near Issoumour, Morocco. The preparation and shell detail is very nice.

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.
