Question

What is one more interesting fact about the Zhenyuanlong that scientist learned by studying its fossil?

Answer 1

Scientists found that Zhenyuanlong had large, well-developed pennaceous wing and tail feathers — including asymmetrical flight feathers on short arms — even though its body and limb proportions make powered flight unlikely. That shows complex, aerodynamic-looking wings evolved for uses other than true flight (display, brooding, balance or gliding).
