How were the prominent, curved spines arranged on the dorsal covering of *Wiwaxia*?
Answer
Organized into two parallel rows running along the length of the body.
The defensive morphology of *Wiwaxia* included prominent, pointed, and curved projections extending upward from its sclerite layer. These spines were not haphazardly placed; instead, their arrangement followed a specific pattern. The spines are generally depicted as being organized systematically into two distinct, parallel rows that run longitudinally along the animal's entire body axis. This arrangement would have presented a formidable profile, significantly enhancing the physical defense offered by the underlying imbricated sclerites against potential predators in the ancient seas.
