Very Rare Bathyuriscus formosus Trilobite from Montana

Description: This Bathyuriscus formosus was 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. Trilobites from Montana are seldom found. The same genus is found in the Marjum Formation of Utah as Bathyuriscus fimbriatus.
