  Still, it falls into Carnosauria, and we have grounds
to distinguish Carnosauria from Allosauroidea.

  Carnosauria == { _Allosaurus_ > Neornithes }.

--|Carnosauria|
  +--+--Carcharodontosauridae
     +--|Allosauroidea|
        +--+--Allosauridae
           +--Sinraptoridae

  Still, I have difficulty dealing with sinraptors as
allosauroids, mainly in the megalosaurian
(plesiomorphic) constructions of their hands, pectoral
girdles, and even skulls.
