Specimen of extreme quality. Unidentified species. His suture lines are wonderfully well detailed.
It is naturally pyritized. It has undergone a taphonomic process of permineralization in Iron Sulfide (Pyrite). Permineralization is a process of fossilization in which mineral deposits form internal casts of organisms.
