1.5" Uncommon Crotalocephalus (Not Gibbus) Trilobite

Do not confuse this with the common trilobite Crotalocephalina gibbus frequently seen for sale. This is a different, much scarcer species that has longer tail spines. It would be about 1.5" long if outstretched. It has about 3-4% shell restoration along its axis.

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.
