Which dinosaur has the longest forelegs?

The heaviest land animal of all time, the BrachiOSaurus. The humerous-to-femur ratio was greater than 1.0 meaning the shoulders were higher than the hips. Other dinosaurs that were originally thought to be bigger or similar, such as Ultrasaurus or Supersaurus either turned out to be BrachiOSaur or more related to the Diplodocus.
