Bargain, 2.8" Crotalocephalina Trilobite - Foum Zguid, Morocco

This is bargain, 2.8" long specimen of the trilobite Crotalocephalina sp. quarried from Foum Zguid, Moroccoo. It has been prepared using air scribes to remove the surrounding limestone and looks like it is about to crawl off the rock.

The preparation is pretty rough, leaving a lot of scratches on the shell, hence the bargain price.

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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
