Two Nice Paciphacops Trilobites - Oklahoma

This is a pair of naturally associated Paciphacops cambelli trilobites from the Haragan Formation in Oklahoma. One specimen is fully enrolled and the other is partially enrolled. Both would be around 1" long if outstretched. They were nicely prepared using air abrasives under microscope and display well on the creme colored limestone.

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.
