carcharodontosaur affinities

["ekaterina amalitzkaya" <eamalitz@hotmail.com>]

Is Acrocanthosaurus considered a carcharodontosaur?  In sereno's trees they 
appear to group together. Though the support for this grouping is really 
weak. With his same matrix there are a few trees nearly as good where it 
groups with the allosaur+sinraptor clade and otherwise outside them in the 
neotetanurans. I remember Currie writing that he had found several unscored 
characters of the braincase that if included suggests and evolutionary link 
with the sinraptor clade. But is there not a paleogeographical problem with 
this linkage?

What are the current opinions of the advanced students of theropods in this 
matter- is there a consensus?
