I was playing with fluffy T. rex ideas. I'm pretty pleased with this concept. Plus there is a generic soldier for scale, so that's cool. Older T. rex Drawings ______2012_______ ______2012_______ ______2010_______ ______2009_______ ______2007________
That's like saying mammals are related to bats and whales. Birds ARE dinosaurs, just like whales and bats are mammals. Of course how similar a given group of dinosaurs looked to birds must be estimated by how closely related they are and what the fossil record says. All known coelurosaurs that have skin impressions show some sort of epidermal fuzz or quills (or feathers, in more derived forms). It's true that some compsognathids may show a patchwork of fuzz and scales, so you could say you are modeling it on those, though tyrannosauroids with preserved skin impressions all seem to be covered up with fuzz. There are also several reports of unpublished tyrannosaurus impressions (I've seen a few) and unfortunately they are ambiguous.
So we don't have hard data, but note that T. rex doesn't "need" anywhere near as much fluff as he illustrated (at its size T. rex could stay warm without any fuzz or fluff at all). So as long as the artist thought it would be cool to make it wooly I just thought it would have been cool to go all the way with it.
Not to be rude or anything, but I wasn't exactly talking about the illustration above, I was mentioning that they needed enough to keep warm, and I didn't mean that bats related to whales etc., It's a fact that birds are related to dinosaurs, and birds today aren't exactly dinosaurs like you said, but relatives.
No, it's a fact that birds ARE dinosaurs. They are maniraptoran coelurosaurs. They are dinosaurs in every way that a bat is a mammal. That's my point. Saying they are "related to dinosaurs" doesn't make any more sense than saying horses are related to mammals.
From my understanding there is cause to believe there were no feathers on at least the underside of the tail and belly from skin impressions. Though I'm sure you'd know much better than I. I got my information from Tomozaurus
Yes, there are seemingly skin impressions from the tail of 2 tyrannosaurids (though neither has been formally published), so it seems reasonable to assert that they reverted to a scaly-tailed morphology ala. Juravenator. The belly impressions are from Tarbosaurus and only might be from the belly. It is ironic, because they actually are formally published and yet their position is more dubious.
Technically there's reason to suspect T. rex may have not had fuzz at all as an adult (or at least at certain times of the year, or in one gender or another), I just meant that as long as you are fluffing it you could have gone all the way. But at the same time it's not implausible that T. rex could have gone halfsies.
I heard some time ago that there were some who believed that the Rex might have actually had plumage like this. I don't know if any of it has been confirmed or not... but... if it did... I imagine it would've look alot like this concept image.
My theory for fossilized imprints of Feathers, is that, perhaps, the Climate change in the Cretaceous period caused the animals in certain areas to develop a way to keep warm, and because Dinosaurs are related to Avians, the only way they could do this was to grow feathers.
The Feathers were only apparent due to natural selection - A Tyrannosaurus whose family migrated Northwards began to adapt a means of keeping itself warm when the somewhat-chilly but not very Snowy Winters of the Cretaceous came about.
