Bargain, 3" Crotalocephalina Trilobite - Atchana, Morocco

Bargain, Crotalocephalina Trilobite - Atchana, Morocco #119896

This is a bargain, 3" long (if outstretched) Crotalocephalina gibbus trilobite from Atchana, Morocco. It has been mechanically prepared with airscribes so that it looks ready to crawl off of the rock. The preparation is a bit rough, leaving a lot of scratches on the shell and their is some shell restoration, 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: 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.
