Cluster Of Reedops & Crotalocephalina Trilobites - Atchana, Morocco

This is a truly impressive cluster of five, beautifully preserved trilobites from the Lhandar Formation near Atchana, Morocco. There are four curled Reedops along with a prone Crotalocephalina. They all have gorgeous, multi-toned shell coloration and excellent preparation. The entire piece measures 4.5 x 4.3" and for scale the Crotalocephalina is 2.15" long. It display nicely either sitting flat on a surface or with a display stand (included).

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.
