4" Flying Crotalocephalina Trilobite - Huge Specimen!

This is one of those trilobite specimens that makes you say, "wow they really do look like little aliens". It's a fantastically prepared Crotalocephalina gibbus from Atchana, Morocco. What makes this particular specimen so special is it was prepared in a "flying" pose by removing most of the rock from underneath so that it is perched on a pedestal. Even much of the matrix was removed from underneath all of the pleural spines. This would have taken DOZENS of hours of preparation work by a very skilled preparator under microscope.

The specimen is near maximum size at 4" long (if outstretched) and has been prepared so that it flies above the limestone base.
