These faunas come to mind

Morrison: _Allosaurus_, _Saurophaganax_, _Ceratosaurus_, _Torvosaurus_ - 
though I'm not certain off-hand how the range of each overlapped temporally 
and geographically.

Wucaiwan: _Sinraptor_, _Monolophosaurus_

Shangshaximiao: _Yangchuaosaurus_, "_Szechuanosaurus_"

Baharija: _Spinosaurus_, _Carcharodontosaurus_, _Bahariasaurus_, 
_Deltadromeus_

Wealden: _Baryonyx_, _Altispinax_, _Neovenator_ - again, I'm not certain how 
these big theropods overlapped temporally and geographically.

Cheers
