Rare Dicranurus & Reedops Association - Black Cat Mountain, Oklahoma

This is a fantastic association of a rare Dicranurus elegans underneath a Lochovella (Reedops) deckeri from the famous Black Cat Mountain trilobite quarry in Oklahoma. The Lochovella is 1.7" long, superbly preserved and prepared. Just check out all of the shell detail and eye facet preservation.

The Dicranurus is 1.6" long and looks complete, just with one cheek slightly shifted. It's tail is directly underneath the other trilobite so it couldn't be fully exposed.

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 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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
