Where were the primary fossils of Wiwaxia corrugata discovered?
The Burgess Shale in the Canadian Rockies of British Columbia
The entirety of our primary understanding regarding the morphology and life of Wiwaxia stems from fossils recovered at a single, highly significant geological site: the Burgess Shale. This location, situated within the Canadian Rockies of British Columbia, is renowned for its exceptional preservation quality. The environment of the Burgess Shale allowed for the rapid burial of soft-bodied organisms, preventing decomposition and scavenging, thereby preserving intricate details of creatures like Wiwaxia that would otherwise have left no substantial fossil record. This unique preservation context is crucial for studying early animal diversification.
