Horse-sized dinosaur shows how T.Rex became king

0

WASHINGTON: A newly discovered cousin of the T. rex may explain how the legendary dinosaur leapt in size to become undisputed king of the food chain, scientists said Monday. Until now, researchers have had little evidence of how the iconic predator became one of the largest carnivores to ever roam the Earth before the dinosaurs went extinct 65 million years ago. The answers could lie in the brain of Timurlengia euotica, a previously unknown relative of the T. rex. Timurlengia euotica was far smaller than the elephant-sized T. rex, but had already developed the large brain it needed to track and devour prey.
