YohoiaDescription: Yohoia tenuis derives its genus name from the location that also lent it name to this spectacular window on early life: Yoho National Park, site of the world famous Burgess Shale. It was presumably a benthic Yohoiaorganism that made a living crawling on the seafloor. It falls within the so-called large appendage arthropods, the most distinguishing feature of this fine example. I have included a negative photo which helps to show off the bent arm, eyes, and segmented body. Coming from the famous Burgess Shale Fauna, this is a highly-desirable member which will make a fine addition to any collection of Cambrian Explosion fossils.
