Spiny Comura Trilobite - Exceptional Preparation #154303

This is a 2.2" long, fantastically-prepared, super spiny Comura bultyncki trilobite. Just check out the shell detail including eye facets and dozens of free-standing spines. Probably 50-60 hours of prep work went into this marvelous specimen.

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.
