2" Spiny Koneprusia Trilobite - Ofaten, Morocco

This is an excellent, 2" long specimen of a super spiny trilobite (Koneprusia dahmani) collected near Ofaten, Morocco. It is a very time consuming process to free all of these long spines from their limestone tomb requiring a tremendous amount of skill. A trilobite like this would have probably taken in the area of 60 hours of work under high magnification using air abrasives. All of the spines look original and restoration is only about 2% 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.
