The dinofuzz was not preserved, but inferred from its phylogenetic position 
(between compsognathids and maniraptorans on the
outside, and _Dilong_ on the inside).

The forelimbs are fairly well preserved and are very long. I don't see that the 
actual bones, or the reconstruction for that matter,
are particularly "wing-like" beyond the normal coelurosaurian condition. 
(Granted, relative to a ceratosaur, coelurosaur arms are
pretty "wing-like"!)
