How did T rex become so big??

A newly discovered species of dinosaur could hold the evolutionary key to why T-rex became so huge and dominant.
The new Tyrannosaur, named Timurlengia, is 90 million years old. It comes from a point in the fossil record just before Tyrannosaurs started to evolve their great size.
Discovered by US and Russia-based scientists working in Uzbekistan, and studied at the University of Edinburgh, the creature's skull appears to hold some of the secrets to Tyrannosaurs' success.
