My data says (humerofemoral ratios)-
Gorgosaurus librartus (CMN 2120) 31%
juvenile Gorgosaurus libratus (AMNH 5664) 29%
Daspletosaurus torosus (CMN 8506) 38%
juvenile Tyrannosaurus? bataar (IVPP V4878) ~33%
Tyrannosaurus rex (CMN 9380) 28%

It looks to me that Tyrannosaurus rex has shorter forelimbs than other
species.  What specimens are you using to support your statement?
