2.55" Spiny Zlichovaspis Trilobite - Excellent Preparation

Spiny Zlichovaspis Trilobite - Excellent Preparation #222270

This is a very nicely prepared, 2.55" long, spiny Zlichovaspis trilobite from the Lhandar Formation of Morocco. It is 2.55" long with excellent preparation and dozens of tiny spines covering its shell. There is the head of a second specimen leaning up against its thorax. One of the better examples of the species that I have seen.

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.
