Huge 5.8" Zlichovaspis Trilobite With One Orange Eye

This is a HUGE example of Zlichovaspis rugosa from Ofaten, Morocco. It has a bit of an arch to it and the head is tucked, but would have been about 5.8" long if completely outstretched. Another interesting feature of this trilobite is that the left eye is orange. Orange eye preservation is occasionally seen on trilobites from this locality but it's pretty unusual for one to have one orange eye and one black one.

The preparation is exceptional and the trilobite has been pedestaled, leaving it flying above the base on a pillar of limestone. There is only about 1% 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: 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.
