Feathers Where Around From The Start

Hm...Interesting...However, the thought of almost all dinosaurs with feathers doesn't seem too realistic, considering Tyrannosaurus, sauropods, stegosaurs, and ankylosaurs.

Interesting to say the least.

Interesting, I don't thing it's true but, still a cool find.

Well, they found evidence of feathers on ceratopsians too, so it's not impossible.

For the majority of the species I believe you are all correct in doubting the existance of feathers and after thinking about it, this find suggests that proto-feathers were a base trait of the archosaurs that evolved into dinosaurs with some holding on to them  like this new species and maniraptora while others lost theirs or at least held a minimal amount.

I doubt that anything other than small-mid sized theropods and very few large theropods had feathers and Rex Fan, o be exact, they found evidence for quills, fairly similar, but not exactly feathers. 

Personally, I think T. rex did have feathers... Also, imagine a triceratops with a ton of feathers mounted to the backside of its frill, which it can raise like a peacock.

EDIT: Oh, I forgot, Fethurz! :3

Didn't baby and youbenille trexes have feathers?, i bealive that all teropods at some point of there lives had feathers

Concavenator had feathers too. On it's arms...

UCMP, my point was that many(if not all) dinosaurs probably had feathers or feather like structures(maybe not the really primitive ones though like Eoraptor). Maybe not all over the bodie, but in the case of Triceratops, maybe quills over the hips. An adult T.rex might have some on the head. Stuff like that.

Well, i'll have to concede most small dinosaurs probably did have feathers. And indeed, this little 4.5 meter long ornithiscian would need them for the colder conditions it lived in.

However, large bodied dinosaurs, for example tyrannosaurus, had no need for them. A small amount could work as a mating display perhaps, that much i will confide. The larger animals, and especially herbivores had no need for feathers, as it is thought they could maintain their own core temperature without the aid of insulation.

I really hate the idea of dinosaurs having feathers, i know its definately plausible, but i would hate to think of a large predator/ginormous chicken with teeth chasing its prey, which would be very, very amusing, rather than my more preferred sight of it.

Depends on how the feathers look. If it's like the feathers on the Gorgosaurus from March of the Dinosaurs (I believe the name was), then that's fine. If it looks like a big freaking chicken, no, just no. 

Dinosaurs were pretty much birds. Some were more like crocodiles and Rhinos, but the ones that have somewhat of the same bodystructure of a basic raptor is a bird by my book. Whether all of them had feathers is not known, but I think it was that way.

Ok, I've had it with people saying that a T. rex with feathers would look like a giant chicken. To anyone who currently thinks that, here's my finger

*grabs knife and chops off middle finger, hands it to all people*

Just look at these:

Your arguement has been invalidated.

You can keep your finger Silver cause I think many species had feathers. I showed many feathered dinosaurs in Mesozoic Marvels: Northern Survivors(even the big tyrannosaurs and ceratopsians).
