What this thing bears an uncanny resemblance to, in my mind, is
_Monolophosaurus jiangi_ (see _Canadian Journal of Earth Sciences_ , vol. 30
, p. 2029). The way the crest begins just in front of the eyes, for
one thing, is more like _Mono_ than _Dilo_. The lacrimal looks VERY like
that of _Cryolophosaurus_, and the quadrate/quadratojugal/jugal area looks
much like _Sinraptor_. I wouldn't be surprised if _"D". sinensis_ turned out
to be a primitive tetanuran or basal carnosaur.
Just a thought.
