Be honest, every time you have watch Jurassic Park you laugh at the T-Rex’s impotent arms as they flail around hopelessly out of sync with its monstrous body. The delicate little limbs have provoked a lot of mirth, despite the rest of its colossal body instilling horror in those who see it.
However, the pathetically limp arms may not be as useless as we originally thought. In fact, they may even be more dangerous than the T-Rex’s sinisterly sharp teeth…
A T-Rex’s arms are very out of proportion to the rest of their body, measuring a mere one meter in length. Some scholars have attributed their stunted growth to ‘vestigial’, meaning that over years of evolution the frame of a species adapts and changes, losing some of its function.
However, recovered tyrannosaurus rex bones show that these arms would not have been entirely surplus, for they had deep muscle attachment meaning that they would have had alarming strength.
Early in the discovery of the T-Rex, it was thought that the reason for the tiny arms having such strength was to assist with copulation, giving the male limbs in which to hold on to their mating partner – for obvious reasons, they couldn’t use their humungous and razor sharp teeth.
It was also thought that the arms were to help the dinosaur hold down its prey. Much discussion surrounded this theory, but scholars ultimately dismissed it.
Now after decades of careful work, experts believe that they have an explanation for the tiny arms on the famous Tyrannosaurus Rex…
