T. rex's arms helped them stand up

It is one of the most enduring mysteries of paleontology - what the fearsome T. rex used its arms for, and why they were seemingly so small.

Now Japanese and American scientists think they have come up with an answer.

By running computer simulations and examining the joints of dinosaur fossils, researchers at the University of Oregon and the Tokyo's National Museum of Nature and Science found that the Tyrannosaurus could often be found crouching down or lying prone.

The arms, it transpires, were a very good design for righting the beast when it wanted to stand up.
