Wow thanks a ton that was really well explained however i do believe that there would be some kind of follicles on all of its skin, maybe it didnt. i was saying that it was a possibility on some parts of the body so not to make a tyrant chicken yes. also im not a feather hater i like feathers they look cool. we should talk more.
Oceansss you really didnt help i literally just explained how dinosaurs dont have feathers tsaying they do with out an explanation doesnt work and check this out : A lack of quill knobs does not necessarily mean that a dinosaur did not have feathers. Finding quill knobs onVelociraptor, though, means that it definitely hadfeathers. This is something we'd long suspected, but no one had been able to prove. you should do your research a bit more
also oceans just cos a few dinosaurs had feathers doesnt mean they all do t rex and velociraptor are unrelated they could have taken different paths when feathers evolved
also thanks paleominer i didnt know feathers evolved on dinos so early i guess the just took to the air in the jurassic, could you please give me the name of the feathered sauropod
that does mean that coelophysis had feathers right?
wow no one has said anything in a while sorry i think i turned this discussion into a bit of an argument, lets do something a bit more productive like dinosaur suggestions.
I have received information from my friendly neighborhood paleontologist (seriously his names Mark Thompson discovered Julieraptor, in the world record books for most preserved dinosaur, is a recognized professor in a Shanghai university and has a rock company in Germany I believe. http://dinosaurman.com/) appareently there is 100% proof new born tyrannosauruses and some juveniles did have feathers, how ever he does believe that adults did not infect have feathers so yeh id go off that.

Sorry, i've been really busy recently (school :| ) and I just saw your message now. Yes..maybe it's getting a little bit disgusting, but at all, it's nice to discuss this kind of things. To ansewr your two questions:
1- We have no evidence of feathers in sauropods, but as I said before: the absense of evidence is not the evidence of the absense. Sauropods are saurischian dinosaurs and share a common ancestory with theropods. Also the skin impressions of sauropods only show that they didn't have feathers in those regions of the body. BUT...since sauropods are herbivores and, well, gigants in the majority of the cases. Herbivores need to radiate more heat due to their diet, breaking up celulose from the plants consumes a lot of energy and radiates a lot of heat, their massive size would also radiate more heat and would make them eat more. So it's verry unlikely that bigger sauropods from the warmer regions would have feathers. But sauropods in general still have 40-50% of chance to have feathers due to their ancestory. In the larger species the feathers wouldn't cover the whole body (as the evidence show) but if present, they would be stage 1-2 feathers covering small parts of the body (mainly in the heat dince it radiated less heat than the rest of the body). The more primitive, smaller and/or the polar/sub-polar sauropods would have feathers covering more parts of the body, they could also be present in the juvenile as plumage and than be lost, just like ostriches and imperial-penguins do. But since there's no evidence - because feathers are really delicate tissues and decompose easly, requiring extremelly specific conditions to be preservated - the book is left open, we can not dicart the possibility of sauropods having feathers, it's all about what you think is right (untill evidence show up)
2- There is still no evidence of feathers in Coelophysis (at least not in my knowlage) so all I say here is meerely speculations and probability. Coelophysis is a notheropod, this means that it came way before the coelurosaurus (90% probability of having feathers) but after the more basal dinosaurus (that just like I said could have feathers) so it could have stage 1 feathers in some parts of their bodies just like its representation in JC. It also appeared in the late Triassic meaning that the climate was tortuous, with heavy rains and winds due to the Monsoon (at least it is what is said) and the climate was semi-arid in most places. There was also wildfire destruction of forests, leading to a warmer temperature, so the feathers would be few to almost no one in the Coelophysis.
Again, this is only my entirely unprofessional and completely personal opinion based on what I know about the subject (which is not much). It is up to you chose what to belive, i just wanted to bring a point of vew. Thank you for the comprehension (and for the long thexts that I think might seem really boring...and the many gramatical errors...sorry :3)

Wow thanks i do not in fact find that boring it is much appreciated. However it did not understand the reference JC sorry, i mostly agreed with your text, either you put a lot of study into it or your more professional than you think. It is good having chats with other people on these forums, and sharing knowledge / learning new things. Thanks a lot
as to your question PCAwesomeness yes i believe it does as when the Tyrannosaurus got older it might not have the use for feathers anymore (it might just be a covering for early warmth / insulation maybe even a disguise tell me what you guys think) but this is just information im taking from Mark

Seriously, when I showed the text to my boss (a paleontologyst) he said "Are you sure he read this?". Well, anyway, it is just a lot of study (about 8 years) since there's no way i can be a professional at the moment, i mean, im' just 14.

Well, it's your opinion, I can't iterfeer in that, you belive in what you want to. But sice the main function of stage 1 to 3 feathers (the ones that probably cover t-rex, if i'm right) is thermoregulation, an adult Tyrannosaurus still needed them to keep itself warm (and to impress females).
Kulindadromeus, Psittacosaurus and also all birds that we know (including extinct ones) since all of them are dinossaurs

Are you sure it works like that?
this looks interesting.

Well its opinion until proved otherwise, im 13. Sorry i idid not get your first post.
