3.1" Detailed Zlichovaspis Trilobite - Atchana, Morocco

Detailed Zlichovaspis Trilobite - Atchana, Morocco #63378

This is a detailed, 3.1" long specimen of Zlichovaspis rugosa from Atchana, Morocco. It has good shell detail and is nicely prepared with clear eye facets in both eyes. Much of the limestone has been removed from below the front half of the trilobite so that it flies over the rock. A really nice presentation.

There left genal spine and pleural tips have a different color and texture due to weathering. There is about 3-4% restoration to the specimen. Some shell restoration on the middle section of the left genal spine, and the left hand side, top of the tail.

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.
