This is a rare, 2.2" long Odontocephalus aegeriafrom the Onondaga Limestone in Pennsylvania. The location where these trilobites are found was collected out in the 1980s so any specimens coming onto the market such as this one are coming out of old collections.

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.
