Cluster Of Four Crotalocephalina Trilobites - Atchana, Morocco

This is an impressive cluster of four, colorful Crotalocephalina trilobites collected from the Lhandar Formation near Atchana, Morocco. It is a natural association with all the specimens in close association. The largest two trilobites would each be about 3" long if they were outstretched. They have been nicely prepared creating an aesthetic display. Total restoration on this piece is only about 2%.

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.
