Partial Kainops & Paciphacops Trilobites - Oklahoma

This is a pair of partial, phacopid trilobites from the Haragan Formation of Oklahoma. They are both enrolled, with one missing it's tail and the other with it's tail buried in the limestone. One is a Kainops raymondi and the other is Paciphacops cambelli. These species look very similar but Paciphacops has far fewer eye facets than Kainops.

About Trilobites

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.
