Most probably one of the best O. chiefensis ever found. Not the biggest example of this spectacular arthropod but the quality is phenomenal. Coming from an old collection, it was recently re-prepared showing its gracile beauty. The trilobite features the longer genal spines, demonstrating the variation within the same species and has a very detailed typical elongated cephalon .
