What specific structural features found on *Wiwaxia* help define the genus according to preservation quality?
Answer
Delicate, scale-like sclerites
The delicate, scale-like sclerites that covered the body of *Wiwaxia* are specifically mentioned as a feature that helps define the genus. The exceptional preservation quality often found at sites like the Burgess Shale is what allows researchers to study these fine anatomical details. These sclerites contrast with other fossil evidence where preservation might be less detailed, such as in formations like the Kinzers or Polish finds. Analyzing these structures provides critical information about the animal's external defense mechanisms or covering, which is a hallmark trait used for its taxonomic identification.
