Description
as my characters Jared Thushi left and tony Thushi (yes they have weird last names they where created a long time ago ok?
) talk abut the theory of tyrannosaurs with protofeathers jared cant quite understand and goes a little of the subject somehow thinking that t-rex had comical advanced chicken like feathers and even thinks of the animal having a large red crest! which i actually suppose could be possible as Jared makes fun of the theory poor tony tries his best to explain that the theory is quite likely showing that t-rexs protofeathers where hair like,just like most protofeathers are - this is how I feel when I usually try and explain feathered dinosaurs in particular.

Truth be told, if I was in the same room with the creature on the left, I would be running like hell.

i myself can only imagine most dinos with feathers. and although i agree t-rex most likely had feathers, chances are it wasnt covered in feathers, at least when it's fully matured.Β

People need to stop thinking "giant chicken" and start thinking "giant badass flightless eagle with teeth".

Sure! But in fact there was no way t-rex was covered in feathers.Β The bigger the animal is, the more it's body absorbs heat. Animals can not live with too much heat on their bodies. That is why elephants have almost no fur, unlike smaller animals like lions and tigers. And t-rex was larger than an elephant and lived on an Era when it was so hot that the South Pole was a forest, so t-rex would not survive being covered in feathers. SoΒ t-rex was definitaly NOT covered in feathers, but it could have some feathers on it's back and/or on the back of it's neck... and maybe some feathers on it's tail and/or on it's arms. But we can not be sure about it, by the time being.

They had protofeathersΒ
And most/some types of proto feathers didn't trap heat

I said they were not covered in feathers, not that it surely lacked any kind of feather. And since we have no evidence for feathers in T. rex you can not say it surely had protofeathers.
And in fact protofeathers actually trap heat. This is one of the evolutionary advantages of having keratinous integument: it traps water molecules and thus traps heat.

what i believe (and most likely scenario) is that when the t-rex is a chick (or baby or pup or whatever you want to call it) it would have been completely covered in feathers. this would help to camo from larger predators and keep warm as a smaller body mass means it cant hold as much heat. but as it gets older it starts "molting" off its feathers. likely a good part of the body including the head and some parts of the tail/arm would still have allot of feathers in its teen years. but when he/she's reached full maturity they'd loose most if not all of there feathers only having some on parts of the head, back, arms, and the tip of the tail.

This is very possible. You are very ingormed about this subject.
But unfortunately we can only talk about possibilities about this asoect until more fossils are found.

well, as of now we do have SOME skin impressions of adult t-rexes showing them with scales. but as stated before that doesn't rule out the possibility of having some feathers. it's kind of funny and ironic to me that in the case of t-rex, most of the depictions of them having scales would be considered more accurate than the depictions of having them covered head-to-toe in feathers. unlike with most other theropods. (i still stand by that adult t-rexes had some feathers and it's very likely chicks were covered in them)

Not completely though. Feathers and scales cannot replace one another. This is essentially because feathers are a type of scales and once a certain variant of skin covering is present in one area of the body, it's there to stay. That's why we don't see overlapping scales replace hexagonal scales on any dinosaurs or modern day reptiles for that matter.

You do know that by phylogenetic bracketing there is a good chance that T. rex had considerable plumage, right? Also those skin imprints are small patches found along the bottom of the tail, bottom of the foot, and part of the legs. Here is also a tip about how feathers work to thermoregulate. They can be used to help cool down an animal as well since the structure of feathers traps air. By fluffing their feathers as far as possible, a bird cools down as fluffed feathers retain less heated air. Plus birds have other means of cooling down besides that. They can also defecate all over their own legs, the evaporating feces has a cooling effect. Also birds can just wallow in water to cool down, like any other animal.

you do make some good points, but another thing (this theory goes out there alittle) is what if t-rex was like the elephant VS mammoth predicament? the mammoth (like yutyrannus) lived in much colder areas so it needed lots of fur (or feathers in this case) the elephant however lives in warmer climates added with its size has little to no fur/hair (feathers again in this case) and like birds as well, what if it got a temporary "winter coat" that lasted through the cold times but molted off when it gets warmer.Β
remember, i'm not saying t-rex didn't have feather, as a matter of fact i think it did. im just saying it likely wasn't covered in them. keep in mind as well that although what you say about birds (including possibly theropods cause relations) is true, no bird even comes close to the size t-rex was.
but i digress, (if i'm using that word right) as of now we still have no direct evidence of feathers, only clues and hints towards it having feathers. so as of now all we can do is speculate and imagine.Β

Actually Yutyrannus lived in an area that wasn't too different from Hell Creek. Both were areas that were around 10 to 11 degrees Celsius. So your first idea got thrown out the window. As for the molting, however, that is possible, but the new coat would only be slightly thicker or thinner. Molting doesn't mean an animal goes bald for one season.
I say the most likely pattern for T. rex feathers was that the upper body was covered, but the lower body and tail was naked much like an ostrich. Check out Saurian's T. rex to see what I mean.

A T. rex covered in feathers from head to toe would most likely overheat if the coat of feathers was not very, very thin.
You seem to be more well informed than many people I have talked to (that kind of people that act like if it was proved that T. rex had feathers and (even worse) act as if it would not overheat with a huge and thick coat of feathers. Have you ever made any reconstruction?

nothing that i've posted on here, but yes i have come up with my own ideas for t-rex feathers. granted the placement of some of the feathers may not be the most realistic (i like to give them badass feather-eyebrows) but i love to tinker around with some dinosaur designs and what/where feathers would be on them (if any). how about you? any of your own reconstructions?Β
π: 0 β©: 1
I haven't made any reconstructions yet, but I do like a T. rex with feathers on the back of it's neck.

whats your top 3 favorite dinosaurs btw?
π: 0 β©: 1
1- Tyrannosaurus rex
2- Spinosaurus aegyptiacus
3- Deinonychus antirrhopus
π: 0 β©: 1
*in no order* mine are Triceratops, Parasaurolophus, and Carnotaurus.

You seem to prefer herbivores then.

They're incredibly underrated I feel. Granted I love raptors and t-rexes as much as the next person, but considering the awesome defenses and sometimes even dwarfing even the biggest of carnivores, I feel they don't get the love they deserve. plus I feel that when comparing dinosaur carnivores and herbivores, there seems to be a much bigger variety of herbivores. carnivores on the other hand (for the most part) seem to all look similar or at least all be very similar in some way to each other.Β
π: 0 β©: 1
You are damn right about such comparations. Well done man!
Also I like the way a triceratops would fight a T. rex (triceratops is my favourite herbivorous dinisaur), but I was always a bigger fan of predators. I like animals that have an active and violent lifestyle.
π: 0 β©: 1
hmm, well modern rhinos are plant eaters and live with super-violent life styles. same with hippos, elephants, ext.
it's really hard to say about dinosaurs however as all we really have are stoned bones and skin impression. but I imagine (much like many modern animals) there were at least a good number of herbivores that lead very active violent lifestyles. triceratops might have, iguanodon maybe, possibly stegosaurus (with that spiked tail that is honestly surprisingly similar to what Bowser from Mario has...) and this is a shot in the dark and for what I know could be completely wrong but maybe sauropods whacked there heas/necks into eachother like modern giraffes? I don't know. Like I said it's a shot in the dark, they're not related but have a very similar neck so who knows?
π: 0 β©: 1
I know that many herbivores have agressive lifestyles, but I am also a big fan of hunting for food, of killing animals to eat them. But triceratops is my favourite herbivorous dinosaur de to his extremely armored head.
I also love the scene of a tyrannosaurid fighting a ceratopsian (expecially a T. rex fighting a triceratops).
π: 0 β©: 1
those are always fun to imagine and speculate about. and personally, I think more carnivores would be my favorite if we found a quadruped carnivorous dinosaur. at this point in time i really haven't heard of any. if we do find one however, i always loved the image of some type of carnivorous ceratopsid. Β wouldn't that be awesome to imagine? a quadruped sharp-beaked horned predator? (maybe that should have been the dinosaur hybred in jurassic world instead of the I-rex)

In this aspect triceratops could act like a pig-hippo hybrid. Pigs eat every f*cking thing and hippos may huntbkr eat carrion when plants are difficult to find (on the dry season).

your right, it can get really anoying

Although I support the hair like protofeathers, the chickensaurus rex is actually horrfic. Nice pic. I see a little bit of myself in tony...

(guess this depends on how old you are but) chances are noone could have thought they had feathers. even before jurassic park came out allot of people had it in there heads most if not all dinos were scaly reptiles

Oh, this is great. I don't see why people dislike the idea of feathers on dinosaurs so much, I think it would look pretty bad-ass!

I can only draw dinos with feathers now, Harpy feathers it look amazing
