Very 3D Chattiaspis Trilobite

This trilobite is very difficult to find well preserved examples of, but this is a real nice one. It's 2.2 inches long, very 3D and have a nice thick, dark brown shell. There is a minimal amount of restoration on this specimen, with just part of the right genal spine being restored. The rock it's preserved in is some of the hardest I've seen, so the preparation process must have been grueling. You don't see many Chattiaspis offered for sale and certainly not one this nice.
