Hey Guest, want to add your say?

I know trikes have a very powerful bite. And Giags a decent bite I think something like 6800-8900 PSI give or take. Not sure about Utahrapto. Though.

Hmm, PSI is pound per square inch so if I were to GUESS maybe 3-4 tons give or take and 8900 would maybe be around 5-6.5 tons, don't take my word on that though. and trikes I would say would be 5500-8900 PSI.

6800 PSI would be about 3.3 tons, give or take.
Rex had a bite ranging from 6800 to 18 000 PSI (3.3 to 9 tons) I believe. Not sure about trike, but that beak would result in a nasty bite.

Yeah, it's kinda in the mid range for bite force.

It was big, and Allosaurs had a medium-low bite force. Not quite medium, but bigger than low. Spinosaurus probably had a bite of around 4000-4500 PSI (2-2.5 tons).

Giga, trikes was probably the same as Gigas give or take.

Like I said before, Trike's beak would deal out a pretty nasty looking bite.

Even if Trike didn't have a high bite force, the small area of the bite would make up for it.

Most likely.
Now, regarding Utahraptor'a bite force. It doesn't matter. Dromeasaurs were claw killers, not biters.

Oh, thought you guys might find this interesting. apprantly some scientists say Dinsuchus had a stronger bite then Tyrannosaurus. I'm not sure, I think its possible but, not likely.

If you meant "Deinosuchus," the 8 ton crocodile, then yes, it's plausible that it had a higher bite force than Rex. If you meant "Dienonychus," the 400 pound Raptor, then I'm going to ask that you stop doing drugs.
I can see how you made the typo, it would be easy to not notice it right away.

Errrrr... Curse auto correct.... I meant dinosuchus.

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.

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?


"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

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

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.
