Dinosaur bite forces

"The force exerted at one of T. rex's back teeth would have been between 7,868 and 12,814 pounds-force (35,000 and 57,000 newtons). This force would be akin to having a medium-size elephant sit on you."

7,868 and 12,814 lbs translates to between 3.9  and 6.4 tons. As far as  i can see, that's the only mention of bite force numbers in that article

Yep

How much damage would that cause compare to 3 tons?

That much would snap bone like a twig, but yet again anything over a few hundred pounds would do that. a five ton bit would pulverize bone with ease

Twice as much

So would a giga biting in to a neck of a rex kill it?

Yes I'm pretty sure

any animal biting another animal at the back of the neck would kill it. Giga didn't possess crushing dentary though, so it couldn't crush the neck vertebrate. It would, however, do enough damage via slicing wounds to kill the rex.

It would cut the flesh and veins and arterys in the neck of rex

Wait so in theroy does the T. rex bite not help?

Help in what

It does, though i get where you're coming from. The neck is a popular target in interspecific and intraspecific conflict, as it is one of the fasted ways to kill a rival with a quick bite to the neck.

Tyrannosaurus had a tremendous bite force, where as if it got its jaws around the neck of another animal, a quick flexing of the jaws would spell the end out for that animal.

Giganotosaurus on the other hand, wouldl need to shred the skin and get through any major life sustaining structures in order to kill an animal. My working hypothesis is the Carcharodontosaurids shook their heads back and forth violently, as the great white shark and various other shark species do when dealing with prey. Their teeth cut through fat and skin, and they back off waiting for the animal to die from shock and blood loss. That being said, it would take Giga longer to kill rex with a bite to the neck, then it would take rex to kill giga.

Why it had a decent bite of its own and those sharp big teeth that would cut throug even the thick skin of a Dino switch some shaking and kill rex

i explained it in the post above.

No, I just said it would not take longer than rex to kill through a neck bite

OHH okay thanks again for the clear up! :)
