What's that, T. rex? You say you have the strongest bite ever? Well, the ancestors of the crocodile might have something to say about that — and some modern ones, too.

The research team not only measured the bite force of all living Crocodilians (read: crocodiles, alligators, caimans, and gharials), but using what they measured, went back and looked at extinct species, too. The result? The most powerful bite, regardless of era.


For the extant critters, the prize goes to the saltwater crocodile (Crocodylus porosus), of which one specimen delivered a bite of 16,414 N (3,689 lbs) — more than three times the highest recorded value in a carnivore mammal. Even more interesting is the fact that the bite strength of the entire species correlates to body size, and isn't influenced by the size and shape of their jaw, their teeth, or jaw strength.

Using this information, they were able to calculate that the extinct Deinosuchus riograndensis, at 11m long and 3,450 kg heavy, would have had a bite of 102,803 Newtons, around 23,000lbs. T. rex's 30,000-60,000 Newton chomp doesn't seem so impressive now, does it?
