Stealthy T-Rex?

I agree. Wait, you're Hadrisaur Hero? We had a user on these forums named Hardosaur Hero a while back. Sadly, I can't draw a Tyrannosaurus with a ninja mask.

In all likelyhood all predatory dinosaurs had rather drab coloration, as to blend in with the foliage and what not.

A pink tyrannosaurus is gonna stick out like a sore thumb, and let's face it, nobody wants a pink tyrannosaurus..

..stuff of nightmares..

Anyway, if we look at the predators of today, they have a fur/skin coloration that helps them blend in with their environment.

Let's take the arctic fox for example..

In the more wintry, colder months they have a fur coloration that blends in with the snow; in other words pure white

But in the warmer, sumer months they adopt a blacker, silvery coloration to their coat

That's mainly to help the animal sneak up on prey, which makes hunting a whole lot easier

But, that's fur. And if Tyrannosaurus rex had feathers, perhaps they would change with the seasons to help it blend in, and if not Tyrannosaurus, the smaller Tyrannosaur species we are surehad feathers most certainly had this adaptation, namely nanqusaurus, a polar Tyrannosaur.

About a third the size of Tyrannosaurus, feathers most certainly would have helped with keeping the tyrannosaur warm in its climate, and perhaps the coat of feathers would change with the seasons as i've stated above

Back to the main point,most predators hunt by ambush, and as a result, are 'stealthy' to some standard, Tyrannosaurus wasn't a speed demon, sure it could run fast for short distances but that expends energy, and most predators look for the easiest, quickest way to make a kill

Yes, I believe T.rex would have been stealthy since it was built to be an ambush predator rather than a marathoner.  Carnosaur is right, predators look for the most efficient way to make a kill.

But it's more than just camouflage and physical characteristics that would make T.rex an efficient hunter.  Patience and timing are two of the greatest virtues that predators must have.  Wolves stalk herds of caribou for days sometimes, and crocodiles can hold their breath for a long time in order to hide under water in order to camouflage themselves.

Well lately there's been more evidence of T-Rexes being pack hunters, so...

Most certainly Rex could be stealthy. Something similar in colour to the JP Tyrannosaurs, but the ground wouldn't shake and there wouldn't be that steady booming as it walked. Of course, it wouldn't be completely silent like the JP3 Spino either.

Any predator can be stealthy. Larger theropods probably had pads in there feet to muffle the sounds of there foot steps.

What if it used a similar hunting method to that of the first humans. Maybe it would run into a herd of Hadrosaurs and then just follow one that was seperated for a few days. Hadrosaurus definitely weren't too stupid to feel emotions and I'm fairly sure that having a T.rex follow you can be quite disconcerting. Because of it's incredible smell it could probably follow an animal for days or even weeks. Imagine you're that poor hadrosaur. You've been constantly running for many hours and have no clue where your herd is and then boom a T.rex appears on the hill you passed a few minutes ago. If you don't die by exhaustion or get eaten while sleeping than ther's a good chance you'll be scared to death.

I like UCMP's idea. It could quite possibly be one of the most accurate results provided Rex didn't get the kill right away.
