QuoteYutyrannus lived long before T. rex, in the early Cretaceous Period
A newly described relative of Tyrannosaurus rex is the largest known feathered animal - living or extinct.
The feathered meat-eating dinosaur lived about 125 million years ago and is estimated to have weighed a whopping 1,400kg as an adult.
The new species, known as Yutyrannus, has been identified from three fossils found in north-eastern China..... rest at the link
Well there goes Jurassic Parks credibility :D
Interesting.
I wonder what purpose the feathers served?
Also, I wonder how the wings are with BBQ sauce...

Apart from flight feathers insulate and often form part of a species sexual dimorphism. It has been theorised that dinosaurs were warm blooded so insulation would be a good thing. Ostriches can't fly, are warm blooded and highly sexually dimorphic.

Birds are thought to have descended from dinosaurs and are all warm blooded, so yes.

Yup, Building a dinosaur from a chicken (http://www.youtube.com/watch?v=0QVXdEOiCw8) is one of my favorite TED talks about the subject.
