I have heard of an Allosaurid, Acrocanthasaurus atokensis that may have
approached T. rex size. It too had a skull over 5 feet long and teeth ~8
inches long and believed to have been in the 40+ foot long range.
Interestingly, A. atokensis may be a_little_older_  than Gigantosaurus or at
least seems to have been it's North American counterpart of Aptian-Albian
age.
