_Longisquama_, with its wide-open antorbital fenestra, certainly is an
archosaur, and, since it possessed a furcula, is likely also a primitive
arboreal dinosaur. (We'll know better when its pelvis and hindquarters are
discovered.) Its dorsal featherlike integumentary structures could well be
precursors of feathers, and suggest that feathers or other featherlike
structures might be found preferentially along the backs of dinosaurs. This
is how I asked Luis Rey to reconstruct the dino-birds for my article in
_Omni_, and such is also the case with the recently discovered
_Sinosauropteryx_.
