Bargain, 2.1" Crotalocephalina Trilobite

This is a bargain, 2.1" long specimen of the Lower Devonian trilobite Crotalocephalina gibbus. The hard limestone surrounding it has been removed so it looks like it is almost crawling off of the rock.

The preparation is a bit rough resulting in many surface scratches to the specimen hence the bargain price. But, it has a lot of shell detail and no restoration.

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.
