1" Kettneraspis Trilobite With Ventral Phacopid - Black Cat Mountain

Kettneraspis Trilobite With Ventral Phacopid - Black Cat Mountain #209153

This is a cool association of 1" long, spiny Kettneraspis williamsi trilobite with a ventral phacopid trilobite. It's hard to tell if the phacopid is Kainops, Paciphacops or Lochovella since it is upside down. Exquisite preparation of this piece with air abrasives under microscope by Bob Carroll. Both trilobites are located on a thick, section of creme colored limestone.

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.
