The most famous of all dinosaurs has his aspect slightly modified in lights of new studies. Its skull appears to be narrower than previously thought while its tail was beefy. Direct evidence of feathers on the 9 meters long tyrannosauroid Yutyrannus, further comfort the idea that T-rex was also at least partially covered with feathers.
