Arched Over Crotalocephalina Trilobite - Foum Zguid, Morocco
This is a nicely preserved, 2.8" long (if outstretched) specimen of the Devonian trilobite Crotalocephalina sp.. The hard limestone surrounding it has been removed so it looks like it is almost crawling off of the rock. Very nice shell preservation and good preparation.
