Finally, there is good evidence that large tyrannosaurs had feathers! This is outside of the true tyrannosaurs, being more closely related to creatures such as Guanlong, but sheer size alone makes it a good bet that Tyrannosaurus had feathers.

1. Well, actually there is evidence for feathers on tyrannosaurus. Mainly in the younger specimens though.
I know, it's Yutyrannus, but it is a lot smaller and more slender than T rex also its area seems colder(nearly anything there has feathers), still feathers for a T rex doesn't seem unlikely.

2. I also think feathered dinosaurs look cool. However, I only think the dinosaurs like velociraptor and troodon look good with them. Others like more primitive theropods look awful with feathers. However, they has been only one feathered dinosaur more primitive than ceolosaurs. Others had quills.

3. There has been no evidence of feathers in sauropods. In fact, there had been no findings of feathers in any other dinosaurs besides ceolosaurs and scirumimus (a megalosaur). However, like I just said, some members of the ornithiscia have been found with quills. Nothing more, nothing less.


I know, this was just theory, but we have found feathers in Psittacosaurus, who isn't even a Coelurosaur.
As I said, the "feathers" in animals like psittacosaurus were only quills. Not really feathers, but advanced scales.

Thats true, but this can be also claimed as a kind of feathers.

I guess. They may be regarded as feathers, but they are not.

Maybe Tyrannosaurus was like this

Looks likely, but it was larger than Yutyrannus and lived in a warmer area.
This reconstruction looks more reasonable. However, I think if T-rex had feathers at all, they would be a row of quills along the top of the head and back, rather than an homogeneous cover of short feathers over parts of the body. The function of these quills would be just display, since the huge dimensions of this dino and the climate in which it lived would make protection from cold weather unecessary.

These are at least feather like structures, and they can be regarded as ancestral to true feathers. I think theories of many other dinosaurs outside coelurosauria being feathers can´t be romed out, for example i could imagine many small ornithopods being feathered while the line evolving into marginocephalians kept the primitive quills (wasn´t there a study saying heterodontosaurs to be close relatives of marginocephalians btw), and larger forms like hadrosaurs lost them again. I could also imagine some quills on stegosaurs, maybe to serve as an intimidation or for finding a mate together with the plates and spikes (the look seems likely to me)

Exactly. Quills shouldn't be called feathers, but feather-like structures. As far as I can tell, only ceoulosaurs and supposedly scirumimus sported true feathers. Though scirumimus might be a ceoulosaur.

Of course it could be, but as long as we have no evidence, it should be claimed to be a Megalosaur.

Feathers in dinosaurs and the evolution of birds definitely is a complicated subject. At the moment, I guess nothing debunks displayinga lot of dinosaurs with featherlike body covering, but nothing confirms it either. We have some fossils with skin impressions (mostly large ones btw, so maybe small animals had feathers but larger ones hadn´t), and many other with feathers. As long as there isn´t more concrete evidence, it remains everyones imagination, except for maniraptorans which certainly were feathered altogether.

IMO, I don't think an adult T.rex was feathered, probably only when it was young I think it lost feathers when it grew
It was an advanced tyrannosaurid while Yutyrannus (which was found with feathers) was a primitive tyrannosauroid?
So just because Yutyrannus had feathers, why the hell would that apply to T.rex?

The ceolosaurs were the most advanced group of dinosaurs. As the family tree got more and more advanced, feathers became more evolved. It only makes sense that the most advanced dinosaurs had feathers.

For anyone who is still trying to grasp the idea of t.rex with feathers, imagine it as a giant, dinosaurian gastornis.

Gastornis is a bird, which makes it a dinosaur. Otherwise, I agree.

Evolution is about adaptation. You seem to believe in a teleological process, where nature inherently tends to create more 'advanced' features with time. Feathers are more advanced than scales only in the sense that they appeared later. But if scales or naked skin were more useful to a given animal in a given environment it's likely that that animal would retain those features - or revert to them.

Still, feathers have not been found in any therapods more primitive than ceoulosaurs with one exception, sciurumimus, which might not have been a megalosaur. I know that evolution is about adaption, but in this sense, it is about, well, being more advanced.

Just to put the nail in the coffin.

The person in the link puts up a couple of very good points.
