April 5 (UPI) --The Tyrannosaurus rex's arms may have evolved to become extremely short to lower the risk of bites while feeding in packs, a new study says. A 45-foot-long T. rex may have 3-feet ...

Extinct for 66 million years, T. rex still inspires speculation about its anatomy, behavior and fierce physique. One conundrum: its peculiarly short forelimbs, which have relatively limited mobility.

For many years, it was assumed that the T-Rex's tiny arms were merely an evolutionary holdover, much like a human's wisdom teeth or the wings on certain species of flightless birds. Over the years ...

In short, it’s not a football death sentence. Ultimately, while some teams have a cutoff they won’t go beneath, many feel arm length can be overrated depending on what can simply be seen.

This dinosaur’s arms and hands had become so reduced that it is difficult to imagine what they could have possibly done with them other than impotently flap them around. We may never know for sure.
