http://www.washingtonpost.com/wp-dyn/content/article/2009/09/17/AR2009091702573.html?hpid=sec-nation

A fossil of an ancestor of T.Rex was discovered in mongol.
It's similar to T.rex, but it's size is as big as human's.
Most people who saw the fossil thought that it's child, but it's not so.

This fossil indicates an interesting thing. Until recently, It has been believed that the feature that their forelimbs are very short is caused by their enormous size. But this species has little forelimbs like T.Rex despite of their small size. The hypothesis is proven it's wrong.
