Most probably one of the best O. chiefensis ever found. With its impressive 48 mm (1.9") it is definitely one of the bigger examples of this spectacular arthropod. Coming from an old collection, it was recently re-prepared showing its gracile beauty. The trilobite features extremely narrow genal spines, demonstrating the variation within the same species and has a very detailed typical elongated cephalon .
