Which major fossil site in Yunnan, China, represents another critical window into Middle Cambrian life for *Wiwaxia*?
Answer
Chengjiang Biota
The Chengjiang Biota, situated in Yunnan, China, is the second major site of importance for *Wiwaxia* finds, alongside the Burgess Shale. This location offers a crucial perspective into Middle Cambrian life, similar to the Canadian deposits, because it also preserves soft-bodied organisms remarkably well, though sometimes the specific preservation matrix and styles differ. The presence of *Wiwaxia* here, along with the North American finds, highlights a significant level of faunal interchange occurring between continents that were arranged differently during that era, even though some sources suggest these Chinese specimens might be slightly younger than the Canadian ones.
