The biggest t-rex was 65 feet long was it the biggest theropod ever?

The largest therapod ever has not been exactly defined. There are ties between Tyrannosaurus rex, Spinnosaurus aegyptiacus, and Carcharodontasaurus saharicus. All reached about the same length, and weight. Also, Tyrannosaurus did no get to be 65 feet long. The largest known specimen was about 40 feet long.
