Bargain 3.1" Crotalocephalina Trilobite
This is a bargain 3.1" long specimen of the Devonian trilobite Crotalocephalina gibbus. The hard limestone surrounding it has been removed so it looks like it is almost crawling off of the rock. The preparation is a little rough and there are a few patches of shell restoration, hence the bargain price.
