Cool pic!!!! Sorry! The pun forced its way out! Really nice pic, though. Nice use of feathers and it certainly seems plausible, given the now known propensity for even large tyrannosaurids to don feathers and the cold arena they're in. Even mammoths, very similar mass-wise, had hair. Looks like I'm gonna have to start adding feathers to many of my dinos in new pics!
haha thanks! I agree, but there are some other interesting pointers - the surface area of dinosaurs was possibly much bigger in proportion to their size (long tails and so forth) so they may have lost heat more readily. And also, feathers can be used to cool down too in hot environments! But I like putting a mix of feathers / skin on at the moment - hedging my bets haha!
Not even modern birds are always feathered the same way, in all seasons. Why assume ancient dinos had to be feathered all one way? Many paleoartists today are just as stick-in-the-mud as many of the paleontologists were in Bakker's day, at the start of the Dinosaur renaissance.
Uh, there is a small mistake in your comment, Yutyrannus is not a Tyrannosaurid, it's a more primitive Tyrannosauroid... Also, the Columbian Mammoth was a hairless species, but it lived in a warmer climate than the Whooly Mammoth.
The point about Yutyrannus means little to me, since it is tyrannosauri-FORM and sized similarly, it might be pointing to feathers in all tyrannosaurs. Maybe only for show/SEX, maybe to keep warm in cold winters.
As for mammoths of the Colombian kind. Any proof they were hairless? Did they live in tropical or temperate climes? If tropical, likely hairless, mostly. If temperate, maybe they had hair at times. Who knows? I am the kind of mean, rotten, heartless, dragon-faced bastard who likes to speculate. Scientific pedantry means little, unless you can show genetic differences between and in and among tyrannosaurids and tyrannosauroids means one definitely had feathers and the other didn't.
We have a hard enough time knowing what modern animals can do, never mind thinking we know all about creatures that lived so many eons back. Case in point--hippo meets crocodile, crocodile runs or dies. There was a croc in Africa that attacked and killed adult hippos. Went by the name of Gustav. Unless they faked the footage, one can see Gustav--a HUGE croc--back down an adult hippo and watch the herd of hippos take a defensive stance against him.
You know, me too I think the Tyrannosaurids, like the more basal representants of the Tyrannosauroidea had feathers, sometimes a feathery coat for the small Tyrannosaurs or the ones that lived in cold places, sometimes some isolated feathers (on the back, the arms and the tail for example) in the big ones that lives in warmer climate. I also think that at least large majority of the young Theropods, including the Ceratosaurs, and maybe even the yound individuals in other Dinosaur groups, had feathers, yeah, I love to speculate too. For the columbian Mammoth, the were mainly found in the southwestern states of the USA and in the Central American countries (even if some remains were discovered in the Tenesee), at the times composed by savannas, tropical environnments and semi-arid lands, so it's likely this species, a bit bigger than the Whooly Mammoth, were mainly hairless (maybe like the modern Elephants, maybe with hairs only on the back). Ah, I know Gustave, yeah with a "e" because I'm French , responsible of a lot of attacks toward humans and able to attack the hippos, just because he's big, if other corcs was as big as him, it's predictable that they would attack hippos too.
