What potential function, other than powered flight, is suggested for the pennaceous feathers of *Xiaotingia*?
Answer
Display or ground maneuvering
Although *Xiaotingia* possessed well-developed pennaceous feathers on its forelimbs—the stiff, interlocking type associated with modern flight—the associated anatomy suggests these feathers were not used for powered flight. Instead, the context of its overall morphology, particularly limb proportions, implies these advanced feathers were likely utilized for functions such as display behaviors or for maneuvering while on the ground. This functional interpretation helps paleontologists hypothesize about the ecological pressures driving feather evolution before the advent of sustained aerial locomotion.
