15" Plate With Three Large Phacopid (Pedinopariops) Trilobites

Plate With Three Large Phacopid (Pedinopariops) Trilobites #154687

This is a 15" wide piece of limestone containing three complete Pedinopariops vagabundus trilobites. These large, phacopid trilobites are quarried from the Bou Dib Formation near Mrakib, Morocco. There are three Pedinopariops in the cluster along with a head of a forth trilobite. All of the trilobites measure just over 3 inches in length and have excellent eye facet preservation. Total shell restoration on the trilobites is 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.
