Two, Bargain, Crotalocephalina Trilobite Fossils - Atchana, Morocco

This is a pair of naturally associated Crotalocephalina trilobite fossils collected from the Lhandar Formation near Atchana, Morocco. The larger off the two would be about 3.2" long if outstretched. They have been prepared so that they look like they are ready to crawl off of the limestone. They are bargain priced because the preparation is a bit rough in areas leaving a lot of scratches on the shell.

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.
