2.3" Zlichovaspis Trilobite - Lghaft, Morocco

Zlichovaspis Trilobite - Lghaft, Morocco #98593

This is a 2.3" long specimen of Zlichovaspis spinifera quarried near Lghaft, Morocco. The shell of these species is covered in tiny bumps, hence the species name. Both the genal spines have bene prepared free of the surrounding limestone. There is a bit of separation between the tail and thorax and scratches on the shell from preparation, hence the bargain price.

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.
