But we only found a patch of naked skin, while the ancestors of Tyrannosauroids were clearly feathered. And Gorgosaurus, in the environment, would freeze to death without feathers.

Yutyrannus is irrelevant in this case, Dilong was found to be fuzzy before the former and it wasn't a mystery. Only the ever-complaining naysayers were demanding that larger tyrannosauroids should be restored with scales only. Now they're pulling the "But Yixian was much colder" argument again, so really, there's nothing capable of defending WWD3D having bald tyrannosauroids other than the fact that they were made to fit the paleontological 'taste' of the creators. :P MOTD got it right earlier, despite having less anatomically accurate animals (euh, dem troodon arms q.q).

Feathers aren't necessary for survival in colder climates, as proved by Edmontosaurus and other ornithischians without developed feathers living in northern parts of the globe when it was cold.

Entering the "Feathers in the cold" argument, I don't like people who draw or represent Sauropods Hadrosaurs and Thyreophorans with feathers just because "the place was cold". I mean, Suropods were big animals, couldn't they have thick layers of fat to shelter themselves from the cold? Above that, all of the previously mentioned animals have skin imprints from many parts of the body, and they're all featherless imprints, actually, the kind of skin they show is a type of skin which isn't proper for the deveopment of feathers if I'm not wrong. So for me not everything needs to be fetahered in a cold climate.
(Please don't get me wrong, I think Theropods and Marginocephalians could be feathered at such climates, I was just talking about Hadrosaurs, Sauropods and Tyreophorans)

There'll be no foot-walking! Just air-flying!

The thing is, the one rule fits all doesn't work. We can't say that just because we found dinosaurian scales ( which are feathers that stopped developing at an early stage ) on several animals, that that sort ( short, dense, almost non-existent) of integument-type ( scales, feathers, fur...) is found all over in every group.

It would be the same as saying that as African Rhinoceros don't have much hair covering their body, Sumatran Rhinoceros ( of which we don't know the exact integument in this example ) can't have long hairs on his body. You see ?

I think it's already confirmed that the scales on Titanosaurids are actually these kind of "dinosaurian scales" ( debunk me if I'm wrong ) so in fact, they are feathers and this does indicate that there might be a possibility that certain sauropods might have had a feathery coat when they came into contact with colder climates. This isn't direct proof for a feathered sauropod, but it is proof for the possibility.

Besides, IIRC, unlike mammals, dinosaurs didn't have brown fat, and that's the type of fat that is good for keeping warm.

Yeah I agree with most of what you said, and perhaps they could have both feathers and perhaps some other kind of mechanism to help keeping themselves warm. Who knows? It's just that, it kind of bugs me that, just because an animal lives in the cold it needs to have feathers...
Also, the "It lived in a Warm Climate, feathers would overheat it" argument pretty annoying, is a Roadrunner scaly? No. Is a Secretary Bird scaly? No. Then why should the Dinosaurs who lived in warmer climates be?

*Looks back at his own post and sees that he forgot to mention Dilong*

D'oh!

What I meant to say was that it's possible that the creators of WWD3D thought that the size difference between the two was enough to justify leaving Gorgosaurus nekked.

Please note that I'm not saying the Gorgosaurus shouldn't be feathered (I believe that feathery integument may be basal to Archosauria, after all.), just that there may be a reason for it being featherless.

I wish I could take the kids in my school on a field trip back in time to the Mesozoic. I know for sure they'd see the true beauty of dinosaurs if they were to see them alive.
