Hello all
don't know if it's been debated before, but the reconstruction shows a
somewhat feathery creature, not to mention the _quite_ wing-like arms. I
know that feathers are known for a long time now, and that it appeared in
coelurosaurs, at least, quite early. Is there any evidence that *G. wucaii*
fossils(s) show these features?

Another member recently noted the presence of a semilunate carpal. After reading "Dinosaurs of the Air", that feature makes it highly likely arm feathers were present, necessitating the need for a way to fold the feathers out of harm's way when not in use
