Bargain, .73" Cordania Trilobite - Black Cat Mountain

This is a .73" long example of a scarce trilobite from the Haragan Formation of Oklahoma, Cordania falcata. It comes from the Haragan Formation near Clarita, Oklahoma. It has been prepared under microscope using air abrasives to reveal the beautiful shell preservation. The left cheek is pushed under the body, hence the bargain price.

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