Large, 2.5" Dicranurus Trilobite With Ventral Lochovella - Oklahoma

Large, Dicranurus Trilobite With Ventral Lochovella - Oklahoma #170269

This is a large, 2.5" long, spine Dicranurus elegans trilobite from the famous Black Cat Mountain Quarry in Clarita, Oklahoma. Most Dicranurus are under 2" and a good one of this size is typically only found once every few years. It has been masterfully prepared under microscope by Bob Carroll and as an added bonus there is a ventrally prepared Lochovella near the corner of the rock.

It is nicely centered on a 7.3 x 6" section of limestone and the distinctive "rams horns" have been prepared free-standing.

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.
