Two Crotalocephalina Trilobites - Atchana, Morocco

This is a beautiful pair of trilobites (Crotalocephalina gibbus) quarried from the Lhandar Formation near Atchana, Morocco. Excellent shell preservation and preparation on both specimens. The larger prone specimen is very large for the species at just under 4 inches long. It is a molt though, missing both of it's cheeks.

About Trilobites

Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
