2.2" Crotalocephalus (Not Gibbus) - Uncommon Species
Do not confuse this with the common trilobite Crotalocephalina gibbus frequently seen for sale. This is a different genus that comes from the area near Lghaft, Morocco. The pygidial (tail) spines are distinctly different.
This is an excellent specimen with very nice shell detail and preparation. It would be about 2.2" long if outstretched. Part of the right side of the thorax has a different shell coloration, likely due to that area of the trilobite being closer to a fault in the rock that where water leached minerals from the shell.

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.
