Dinosaur bite forces

Crocodilians have the strongest bite force at parity then any living animal today. Salties have a bite measured at close to two tons of force, and that came from a seventeen foot long individual i believe. Now, scaling up the seventeen foot croc, a forty two foot deinosuchus would have a bite force of roughly 7 tons; which puts it on par with that of Tyrannosaurus.

I think one group of animals you passed over is the megalosaurs, the larger species(Torvosaurus, perhaps the synonomous Edmarka) have higher jaw mechanic then those of the tyrannosaurs. And indeed, , mechanical advantages calculated for Eustreptospondylus and Dubreuillosaurus (both preserve more skull elements) are comparable if not higher than that of T. rex (Sakamoto, 2010). But like  it has already mentioned, T. rex has other features that indicate that it had larger, stronger bite overall. The megalosaurs, once the larger species have an overall determined bite force, could rival that of the tyrannosaurs.

Deinosuxuscus is an alligator 

IGNORE this post

Ya I heard that to it is awesome

Predator X- I said Crocodilians. Alligators have a bite force very similar to that of the salt water croc, and as it is the biggest species of crocodilian living today, i used it to scale.

Regarding rex bite force, i've seen estimates as high as twenty tons. Frankly, that's a whole lot of bull(Stress in the skull would cause it to fracture, predominatly the maxilla) i haven't seen that nat geo article yet, but i'll go do some digging. I usually put its bite force in the 4-9 ton range

But, doing the math on a fourteen foot american alligator(Alligator Mississipiensis) with a bite force of 2,125 pounds, A 42 foot Deinosuchus would have a bite force of approximately 6,375 pounds.

Here's one post, thers many others though, http://www.livescience.com/18718-trex-strong-bite.html

WAIT!!! sorry I just messed up 13000 pounds 4 times more than previously thought! How many tons is 13000 pounds?

6 and a half tons

"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?
