Well, the Tarbo's treathening roar implies it just came back to its meal reccently. The description states the Deinocheirus was unattended at the moment the smaller theropods came.

I apologize. I just don't see any reason why T-Rex should be having bear-like lips. And besides, its obvious that dinosaurs are more related to birds and crocodiles than mammals or lizards or snakes. We have proof of dinosaurs with feathers. Perhaps predatory dinosaurs were so evolved they did not need such lips. I got links with birds with teeth. The T-Rex having lips may just be speculation.

It's okay, I think I freaked out a bit. I just left a heated row somewhere in the Youtube comments sections, so I was feeling irked

Anyway, as far as I know, there's no evidence to support T. rex having lips or not having lips. Such soft structures would decompose if they did exist. As for their lips being bear-like, that could just be explained as convergent evolution. Ultimately, I think this falls under artistic license.

Yeah, but I doubt the real T-Rex even needed lips. They would make it ridiculous. Lol.

Dude, the fact it would make it ridiculous in your opinion, does not degrade the scientific value.
It has foramina so it at least had some lips.
How big? that's speculation.

Tyrannosaurs likely had thin enamel, so they would have needed lips. I believe lizard-like lips are more likely, although mammalian lips aren't impossible. Crocs don't have lips because their scales are keratinized (I think, correct me if I'm wrong). Those birds don't have lips because they're pseudo-teeth, which are just extensions of the beak. Most modern animals that have teeth actually have lips. Its more than likely they had lips. I believe that Saurian's rex's lips are the most accurate.

Google Saurian rex and you'll see what I mean.

Also, the lips research done in Toronto has problems comparing lizards to dinosaurs and they're obviously didn't realize that dinosaurs are more closely related to birds and crocs, not lizards.

I see it myself and already the Tyrannosaurus looks like a dog-bear-bird hybrid. I don't mind if the T-Rex is feathered, but the lips may just be wild speculation. Evolution suggests that dinosaurs are more related to birds and crocodiles than lizards or snakes or mammals. I an writing a science fiction novel and I already feel pressure from the Smilodon lip theory ( another theory that is possibly being wildly speculated) that is pressuring me to re-write my book all over again.

For one the study done at Toronto doesn't just say that T. rex was related to squamates so that Tyrannosaurus must of had lips. It says that Tyrannosaurus (Please note that the species depicted here is Tarbosaurus, because it is depicted with long-snouted Tyrannosaurs, which are only known from Asia, where Tarbosaurus is endemic to. Tarbosaurus might even be a species of Tyrannosaurus, and, even if it's not, it would still be a Tyrannosaurine.) had thin enamel, which means that to protect its teeth from decay, it would have to have lips. If it didn't its enamel would rot and then it's teeth. Anyways, even if there wasn't evidence for lips, it wouldn't be wild speculation, because they would certainly help. They would protect it when it wasn't using it, in case it brushed up against a tree, for example, it wouldn't lose teeth. Phylogeny has its limits, and birds, again aren't the greatest thing to compare Tyrannosaurus, because bird's teeth are just projections from its beak. Crocodiles and alligators aren't the best comparison either because they have pressure sensors on their snout which would mean that the lips would get in the way (Sorry, when I said that Crocodilomorphs didn't have lips because their skulls are keratinized I believe I was wrong. I say "I believe" because I can't find good sources why Crocodilomorphs don't have lips).

P.S. I actually agree that the idea that Smilodon had lips is a bit far fetched because their teeth extend so far below the bottom jaw.
