I like how everyone is now 100% sure they had feathers, just like everyone (25 years ago) was 100% sure dinosaurs were stupid, stood straight up and where covered in scales. Like how everyone was sure the velociraptors in Jurassic Park were make believe because raptors were actually small. You'll have to excuse me if I don't take certain "Dino facts" at face value when these things have gone under more real life incarnations then the spider-man movie franchise.
Something like a T-rex having feathers isn't impossible, maybe they did! Maybe certain ones did, since we see how different animals can be even amongst their own species, just look at the scaled and scale-less snakes. Maybe they all had feathers but only at certain ages, as adults, children, etc. Dinosaurs turning into birds wasn't something that happened over night, it was a progressive thing. After all, we all came from the ocean, so I seriously doubt their earliest incarnations had feathers.
There is also the little matter of the frog DNA used to create the dinosaurs, which I have to assume altered them in some superficial 'cosmetic' way considering there was enough to change their sex. Funny how people keep forgetting this. So I forget, do frogs have feathers?
