Acrocanthosaurus (according to Phil Currie, whom he and I had a nice
talk), its jus superfical.
Carcharadontosaurus and Giganotosaurus were large, short necked, short

Ala Dan Chure and Jim Madsen jr? I think they have a paper in the
Morrison Volume that the GSA will shortly produce, of course I could be
wrong. I know Dan's been working on Saurophagus (he showed me the
