In the original 1994 description, the authors (Hammer and Hickerson) do say 
"it is possible these [postcranial] elements may not go with the skull, but 
are clearly theropod and are the right size."  The femur and tibiotarsus 
(which appears to be fused) are very ceratosaur-like, but the hip bones are 
more in keeping with the tetanurine (especially allosauroid) affinities 
suggested by the skull.
