An excellent example of a little rarity, particularly of such fine detail and quality of preservation and preparation. The carapace exhibits wonderful morphological features. The most notable being the thorax spines. A Proetida order of trilobites which exhibits long genal spines, short and fine axial spines and numerous pits around the glabella believed to have possibly been used for sensory aid in the murky bottom of the seabed.
