Scarce Cyphaspis Carrolli - Haragan Formation

This is a rare trilobite from the Haragan Formation, Cyphaspis carrolli. It's from the world famous Black Cat Mountain and was collected and prepared by Bob Carroll for whom the species is named. The detail on this specimen is simply amazing considering it's only .58 inches long (not including spine).

I've personally spent weeks collecting this formation myself over the years never have found one complete.
