Very Rare Bathyuriscus formosus Trilobite from Montana

Description: Bathyuriscus formosus is a wonderful treat for the species trilobite collector. They are very rare. This is the first one to ever come across my desk. I obtained it from a well-known collector who lives close to me here in Northern California. The Bathyuriscus was most certainly collected back in the 1970s or 1980s.

The specimen is just about perfect. It has beautiful skin, with all the spines clearly defined. The free cheeks are tightly attached. Be sure to take special note of the axial nodes present. This is the only specimen I have, or, will have of this species.
