.85" Leonaspis Spinicurva With Long Occipital Spine With Morocops

Leonaspis Spinicurva With Long Occipital Spine With Morocops #267218

This is a well prepared, .85 Leonaspis spinicurva from Foum Zguid, Morocco. This scarce species of Leonaspis has a distinctive, long, curved occipital spine. There is a Morocops also present on the piece, but it appears to have been composited onto the rock.

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.
