This is a fabulous spiny trilobite. It is an excellent example of the rare Olenoides trispinus from Utah. This specimen was found by Steve Hess in 1996 and just now prepared. This trilobite was split out in two pieces, with the back (axial) spines and other features still in the counterpart (see photo #2). The top rock was then secured together with the bottom rock that contained the trilobite, making the trilobite essentially whole again. The bug was then microscopically extracted down through the entire top rock to expose the trilobite, spines and all! These back spines stick up from the body of the trilobite, making for a beautiful display. And, as you can see, almost all of its other features were unearthed intact, making it one of the most complete examples of this type ever found. This is a textbook example of an Olenoides trispinus painstakingly prepared with all of its spines intact.
