To which geological epoch is the well-known species *Wiwaxia corrugata* definitively associated?

Answer

The Middle Cambrian epoch

The definitive temporal classification for *Wiwaxia corrugata* is the Middle Cambrian epoch. This classification is crucial for paleontologists as it places the organism within a specific window of the early animal evolution timeline. Understanding this epoch allows researchers to compare *Wiwaxia*'s development and dispersal rates against the backdrop of the Cambrian explosion. The text notes that specimens from different locations, such as the Chengjiang biota in China, can sometimes be slightly younger than those from the classic Canadian deposits, indicating that even within the Middle Cambrian, there were small temporal separations across continents that are studied to track evolutionary spread.
