Awesome Black Cat Trilobite Association - 4 Species!!!

This is an amazing, natural association of FOUR different species of trilobites from the Black Cat Mountain quarry in Oklahoma. Trilobites are fairly scarce to find complete, so getting even two species in close association is unusual, three is very rare, but four?

There is a nice, 1.85" long Lochovella (formerly Reedops) deckeri, next to a large, enrolled Cyphaspis carrolli, a Kettneraspis williamsi and a tail of a Huntonia. They are all nicely located on a solid, 5.2 x 4.7" block of limestone. Nice preservation and prep work.

The Black Cat Mountain Quarry produces a limited number of arguably the most beautiful trilobites in the United States each year. Each specimen is meticulously prepared by quarry owner Bob Carroll under microscope to expose the smallest details. This is a very time consuming process, taking many hours, but yields spectacular results.

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.
