In my Gaia analysis, Scipionyx came out as a basal coelurosaur outside
Maniraptoriformes. In my forthcoming (Dinosauria II) analysis it is in a
similar position: basal to Tyrannoraptora (= Tyrannosauroidea +
Maniraptoriformes) and the Ornitholestes complex.
However, it would be interesting to know what the ADULT animal would fall
out as: in many taxa juveniles tend to be more "basal" in terms of their
character states than the adults. (Incidentally, a quick and dirty
analysis that might result in a good paper: running baby hadrosaurs as
separate OTUs in an iguanodontian study).
Very hard to justify it as a dromaeosaur, though.

Now that's just sad...
