Well, to be fair, we people have some pretty nasty stuff in our mouths too (supposedly one of the worst kinds if bites you can get is a Human bite. Then again, depending on what you’re into, and what kind of bite it was from what kind of human, it could theoretically be one of the better bites you can get )
Anyhow, Hippos have some fearsome jaws. Snap crocs in half like Pocky sticks. Not sure what a few of them could do to a T-Rex’s ankles if they could get close enough.
Actually, its arms were just too short to brush properly.
And the obvious answer to the OP is Twilight Zone standard, it’s MAN. At least a man with a plentiful supply of rocket-propelled grenades and a safe place to launch them from.
A polar bear in its natural habitat might stand a chance if T-Rex was cold-blooded. Then again, so would a penguin.
Well, no, but a man with a shovel, an axe, some rope, and maybe a Leatherman, plenty of time on his hands and a bit of luck could probably take down a T-Rex with just snares and pitfalls. Pretty much your standard brain vs. brawn grudge match.
Actually, it may not take more than standing on the opposite side of a handy tar pit and giving the T Rex the finger. Although it’s really hard to say because we don’t have any exact idea about the T-Rex’s intelligence, agility or speed.
Guerilla’s, not Gorilla’s. A attempt at humor. Har.
The Komodo Dragon does it’s toxic bite as it is one of the few lizards that attacks and eats things that aren’t big enough to more or less swallow whole.
I would say that a wolverine that was motivated enough could give him a run for his money. They are small enough to make a bad target. He could just scamper up the T-Rex’s back out of his reach, dig in his claws and go for a ride. A small and vicious enough animal can take down a much bigger one, it just takes a little longer.
That is precisely what they do. They’ll give it a good bite, and then track it using their sense of smell until it succumbs to sepsis a few days later.
