Cordania & Kettneraspis Trilobites - Black Cat Mountain, Oklahoma
This is a unusual association of two types of trilobites from the Haragan Formation of Oklahoma. There is a .6" long Cordania falcata right next to a 1.15" long Kettneraspis williamsi. The Kettneraspis is partially exposed, but both trilobites have wonderful shell detail and good preparation.
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.
About Trilobites
Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
