Rare, 1.35" Xiphogonium Trilobite - Phenomenal Prep Work

This is a phenomenal specimen of a very rarely seen genus from Morocco, Xiphogonium. This is only the fourth specimen of the genus I've seen and it blows away the others in quality. It's nicely inflated with beautiful shell preservation and was prepared by one of the best trilobite preparitors in the world. Just check out all of the microscopic shell details.

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.
