Description
INACCURATESpeculative breeding plumage in Tyrannosaurus rex. Similar copulation is seen in ratites.
The differences in the skull are because I used two different specimens of T.rex.
Based on skeletal drawing by ScottHartman

"Similar copulation is seen in ratites." looks like ratites were inspiration for more aspects of this art

Yes, I think I drew them too fluffy,the next time I will make them less feathered!

This depends on what region you wanted to draw them.

So it appears you indeed put to long feathers.

The "long feathers" are because I tried to make them look shaggy like an emu,but I failed.

Ah, I see. But emus have a very thick coat of feathers on a wide area of the body while T. rex, that had 8 tons, would overheat with that on the warmer regions. A thinner coat is more accurate in the Hell Creek.

Read all please!
How many heat would a Tyrannosaurus produce?
Ostriches with that cursorial adaptations and hot environment , “warm blooded “ metabolism, lost feathers on the sides, legs, the area near the cloaca and have short and somewhat thin feathers in the neck and head.
Its important to stop making assumptions about the heat retention of primitive feathers and especially the metabolism(but probably high) of Tyrannosaurus.Thermoregulatory topic is very complex.Also,We need more fossils to see how feather density varied between Tyrannosaurs.
So if I have to draw a Tyrannosaurus with minimum feathers distribution and density I will make it similar to an ostrich,also considering those little scale impressions(in this drawing you can see the lower part of the tail as scaly).
The ostrich lives in warm areas and has few feathers, T.rex lived in relatively cold areas but perhaps its size and metabolism counteracts an ostrich's feather distribution…I frankly don't know,I'm not a scientist and Science does not work with opinions or hypothesis shared on deviantart!
On the other hand , I think that we should not "over compare" dinosaurs with mammals, for example; some hadrosaurs and ceratopsians make it well in more or less cold environment without feathers,we should look at the metabolism of this animals.
You are a kind person but your reputation is not very good.Why?

"The ostrich lives in warm areas and has few feathers, T.rex lived in relatively cold areas but perhaps its size and metabolism counteracts an ostrich's feather distribution…I frankly don't know,I'm not a scientist and Science does not work with opinions or hypothesis shared on deviantart!" depends on the area: territories that today belong to Canada would be very cold, maybe even for T. rex.
Also you should notice that:
-volume increases far more rapidly than surface area and similarly shaped animals with different sizes will not deal with heat the same way. That is why, for example, ostriches and emus have different feather patterns.
-feathers, just like fur, create a "sheild" against air molecules and the denser and thicker the coat is, the more difficult it gets for air to reach the skin and so heat is trapped (that is why birds on colder areas have thicker coats).
"some hadrosaurs and ceratopsians make it well in more or less cold environment without feathers,we should look at the metabolism of this animals." how can you be sure that those specimens did not show feathers? They could have belonged to different subspecies.
"You are a kind person but your reputation is not very good.Why?" thanks, and my reputation is not a golden one because I already refuted many pseudo paleoartists here (consider "paleoartist=someone that appears to care more about accuracy, but get's angry when someone shows that something they did is wrong"). You can see that my reputation will be better among those that actually care about accuracy above everything and among those that accept crictiques.
Example: I once said that a certain "paleoartist" put to long lips on a T. rex and instead of giving his reasons and arguments (I mean, if he had some), he simply showed this diamond:
"Dude, I really do not want to block you, because I have never blocked people before, but I will do it if you keep posting the same clueless and uninformed comments under all of my reconstructions of tyrannosaurid theropods. I think I have made it clear already that I do not want to waste my time with you, because you not only lack even basic knowledge on various paleontological subject - from osteohistology and physiology to paleoclimate and ecology; but you are also so stubborn that you refuse to familiarize yourself with the primary literature (that would be scientific papers and technical textbooks) before engaging in discussion with people who obviously know more than you on the subject. Considering all the time I wasted in the course of the last two weeks replying to your nonsense, I will be as polite as possible given the circumstances and tell you this - PLEASE. FUCK. OFF!
If you keep posting under my artworks, then your comments will be flagged as spam and you will be blocked. Consider this your official warning! Good riddance!"
After I gave MY arguments and reasons (and even tough I got FAR more informed since that day), he wrote "Enjoy being blocked, you clueless person. I will leave your comment visible so those people who actually have enough knowledge on the subject can see how ignorant and misinformed you are. For one final time - Good ridance!"
However comments.deviantart.com/1/3531…
The main reason of why I have such a bad image among some people here is because they barely research some aspects and close themselves on many poorly researched claims (some that even f*ck the laws of physics) and when I showed other explanations they simply got angry.

"-volume increases far more rapidly than surface area and similarly shaped animals with different sizes will not deal with heat the same way. That is why, for example, ostriches and emus have different feather patterns."
So what do you think about the feather arrangement of Dryptosaurus for example?Appalachiosaurus?Those medium sized tyrannosauroids...
c2.staticflickr.com/8/7168/648… the difference!
One tip;sometimes you saturate people, you're very insistent with some persons that well, do not want to debate.Sometimes it is better to stop, to not want to have the last word!But yes,sometimes people just don't want to hear...
Also,how old are you?

What do I think? I must know ehere they lived first.
I understand and thanks, but I once realized that we may always commit mistakes when we recreate extinct animals, so if one is not open to debates or crictiques, it would be better for this person to not try to make paleoart. But indeed some people did not hear me after they realized they were wrong (many blocked me after showing they were lacking arguments).

We always commit mistakes doing paleoart!All of my images here on deviantart don´t reflect my current knowledge.Critiques are always useful,but in the correct context.
"But indeed some people did not hear me after they realized they were wrong" this is sad :/
Oh I also 15!

So we are both teenagers and we agree about crictiques on paleoart and people that do not wanna be right YAY

Thanks, at first I wasn't sure about environment the but it ended pretty good actually.
