1.7" Super Spiny Koneprusia Trilobite - Spectacular Preparation!

Super Spiny Koneprusia Trilobite - Spectacular Preparation! #169639

This is a truly spectacular specimen; a large Koneprusia trilobite from Ofaten, Morocco. It was prepared by the best preparator in Morocco and the results are incredible. This trilobite has small spines on all of its spines! These secondary spines are rarely preserved as they are so easily destroyed during preparation. Preserving them requires using fine, low-pressure air abrasives and a lot of patience. This trilobite is less than two inches long but took upwards of 80 hours of preparation time.

It's very aesthetically presented on a natural looking piece of limestone and is not only an incredible fossil, but a true work of art. There is NO RESTORATION on this specimen. The whitish area on the spines is likely due to a calcite seam running through the rock and the spines.

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.
