2.75" Flying Crotalocephalina Trilobite - Lghaft, Morocco

This is a beautiful, 2.75" long, specimen of Crotalocephalina gibbus from Lghaft, Morocco. Nice preparation and shell detail. It has been prepared in a "flying" pose by removing nearly all of the surrounding limestone. This leaves it floating above the rock on a pedestal. The preparation takes lot of time but the results are quite spectacular.

This one is from Lghaft unlike the vast majority of Crotalocephalina which are quarried near Aatchana. They are pretty scarce at this locality and the preservation is slightly different. There is about 3-4% shell restoration on the left side of its head as well as a couple plueral tips.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
