2.3" Zlichovaspis Trilobite - Great Eye Facets

Zlichovaspis Trilobite - Great Eye Facets #69747

This is a nicely prepared specimen of Zlichovaspis spinifera quarried near Lghaft, Morocco. The shell preservation is quite nice, and it has clear eye facets in both eyes. It displays well on the sculpted limestone matrix. Less than 1% restoration along repaired cracks though the very tip of the right genal spine might be a composite. Both genal spines have been prepared free-standing.

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.
