Bargain Crotalocephalina Trilobite - 3"

This is a bargain example of the Devonian trilobite Crotalocephalina sp.. This specimen is arched over but would be about 3" long if it was outstretched. The hard limestone surrounding it has been removed so it looks like it is almost crawling off of the rock. Nice preservation and preparation. No major restoration on this specimen just a few areas where the shell was touched up.
