Huge, 6.7" Spiny Drotops Armatus Trilobite - Excellent Preparation

This is a huge, 6.7" long, spiny Drotops armatus trilobite collected from the Bou Dib Formation near Mrakib, Morocco. With somewhere around 100 free standing spines it would have been a very unappetizing dinner for it's predators. It's a nice looks specimen. This specimen is near maximum size for the species, laid out prone and well prepared. Only about half a dozen of the spines have been restored.

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.
