Onnia Trilobite Cluster - Blekos, Morocco

This is an aesthetic association of chocolate-brown Onnia superba trilobites from Blekos, Morocco. The grouping features one complete but disarticulated individual accompanied by two partial specimens, beautifully arranged on a 3.5 x 3.5" piece of limestone. Masterful preparation reveals exquisite detail and outstanding shell preservation, creating a striking and highly collectible display piece. Total shell restoration is less than 1%.

About Trilobites

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.
