Large, 3.25" Dicranurus Trilobite - Black Cat Mountain

 
 
 
 
Dicranurus is a rare trilobite in the Haragan Formation with only a few complete specimens being found at the Black Cat Mountain Quarry each year. This magnificent example was prepared by Bob Carroll.

This 3.25" long this specimen is very large for the species, in fact the largest, nice specimen that I've seen come out of the quarry in a few years. The horns have been prepared free standing and the shell preservation is beautiful.

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.
