3.25" Crotalocephalina Trilobite - Foum Zguid Morocco

Crotalocephalina Trilobite - Foum Zguid Morocco #89233

This is a detailed, 3.25" long specimen on Crotalocephalina sp. with a mottled shell coloration from Foum Zguid, Morocco. The limestone around it has been painstakingly removed so that it looks like it is ready to crawl of the rock. Only about 1% shell restoration 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.
