Large, 3.5" Crotalocephalina Trilobite - Rock Removed Under Shell
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 trilobite itself is 3.5" long and is perched atop a limestone base that displays nicely on a flat surface. There is only about 1-2% shell restoration on this impressive specimen.

About Trilobites
Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
