A cautionary note here, there is indeed evidence of a large theropod in the
Arundel that is not Acrocanthosaurus. Harris (in the same volume as Lipka's
paper)discusses the proximal caudal that was named Creosaurus potens by
Lull. Though the specimen is woefully inadequate to diagnose what type of
theropod it was, but it is enough to say that it isn't Acrocanthosaurus.
