2.5" Crotalocephalina Trilobite - Perfectly Prone

Crotalocephalina Trilobite - Perfectly Prone #75462

This is a perfectly prone, 2.5" long (if outstretched) specimen on Crotalocephalina gibbus from Atchana, Morocco. The specimen is laid out nicely and well prepared.

There is about 5% shell restoration, mostly on the front of the head where the shell was damaged during collection.

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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
