Arctinurus boltoni Middle Silurian Rochester Shale Formation, Middleport, New York Nothing else found in the fossil record of North America - or even the Western Hemisphere - can compare to the exotic appearance of the Arctinurus, found in only one location in the world. The present specimen is arguably one of the very best, and is exceptional in every way. Arctinurus is regarded as the King of all North American trilobites by paleontologists and collectors alike. These unique creatures are characterized by a unique bat wing appearance on the posterior lateral segments and a very ornate Stealth Bomber-shaped head, or cephalon, with gorgeous multi-faceted eyes. The entire body surface is covered with small bumps, which may have held sensory whiskers, much like a cat, which gives Arctinurus an overall pustolose (pimply) surface texture. The location where these unique specimens were obtained was closed permanently in 2008, making it impossible for new specimens to be collected. It has been expertly cleaned and prepared on its natural shale matrix for display. Trilobite measures 5 x 3 ⅞in
