9 Tiger- Bite force : 1050 psi. PSI: 7700. "a Tyrannosaurus bite could impart as much as 431,000 pounds per square inch (psi), which helped the animal pulverize the bones of its prey to give it a nutritional advantage over other predators of its day. To compare, saltwater crocs were measured at 360,000 psi. Furthermore, by Erickson's calculations, the extinct, limousine-size Deinosuchus, or "terrible crocodile," had an estimated bite force as high as 23,100 psi (102,750 newtons)â greater even than new estimates that put T. rex's bite at 12,814 psi (57,000 newtons). Channeling the force, a Tyrannosaurus bite could impart as much as 431,000 pounds per square inch (psi), which helped the animal pulverize the bones of its prey to give it a nutritional advantage over other predators of its day. That means this feeding pattern arose earlier than previously thought. His estimates claim that the Sarcosuchus bite force could reach 80 kN, which is equivalent to about 8 tons of force, while the Deinosuchus could reach 10.5 tons/cm 2 … In 2012, the team found that a saltwater crocodile packed a bite of 3,700 pound-force (16,460 newtons), By comparison, a human vigorously tearing into a steak tops out at around 200 lbf (890 N). We’ve found only two specimens of Giganotosaurus, so this also give… With a weight that may have been up to 14 tons (Around 8000kg) for the bigger ones, and a length between 40 and 43 feet, they defeat Sue (the largest and most complete specimen of a T-rex), who weighed about 9 tons with a length of around 40 feet. Estimating a mechanical (dis)advantage of 1/6 based on moment arms eyeballed from the skull image, the effective area would have to be 2 square millimeters to produce such stresses---about the head of a pin. Perhaps the scientists ought to double-check their data. 7 Grizzly Bear – Bite Force : 1200 psi. "T. rex was basically eclipsing the highest forces known for any living animal today," says Erickson.

Here are the most powerful dinosaur bites according to various reports and estimations. 4 Hippopotamus – Bite Force : 1825 psi. To compare, saltwater crocs were measured at 360,000 psi.". A group of scientists from Florida State University began by studying the bite force of crocodiles and alligators, which are at the top of today's list of animals you don't want to find yourself between the jaws of. In fact, their bite forces may rival that of mighty T. rex. Previous studies had estimated that a T. rex could produce between 1800 and 3000 pounds of force, but Bates and his team estimate that a T. rex 's jaw … The modern-day animal kingdom’s strongest bite force comes by way of the crocodile, which can exhibit anywhere from 3,700-5,000 PSI of bite force depending on the species. 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). Researchers have calculated the bite force of a Tyrannosaurus Rex to be about 8,000 pounds, twice as powerful as a modern crocodile, This section of Triceratops pelvis shows some 80 T-rex bite marks, indicating a "puncture and pull" pattern of biting, Using the jaw musculature of modern crocodiles, Florida State University researchers calculated that the T-rex might have had a bite force of 8,000 lb (35,586 N), and 431,000 psi. To figure out the bite force of a long-extinct T. rex, the team created a digital T. rex jaw based off muscle features found on close modern-day relatives to dinosaurs, like birds and crocodilians. The Tasmanian devil has the most powerful bite relative to body size of any living mammalian carnivore, exerting a force of 553 N (56.4 kgf). Measuring roughly 42-43 feet long (13 meters) and a hip height of 4 meters (13 feet, Wikipedia), the dinosaur led what Univ… 431,342 pounds per square inch. The dinosaur, they found, could chow down with about 8,000 lbf (35,586 N), more than twice the force of a saltwater croc. This is not realistic. 5 Jaguar : 2000 psi. They had all sorts of scans of a complete t. rex skull and ran them through computer simulations. By comparison, a finch's bite force is only 70 newtons, but its … Dr. Greg M. Erickson from Florida State University has estimated the prehistoric crocodiles’ bite force based on the present-day animal data. Scientists have estimated T. Rex had a maximum bite force of more than six tons (12,000 pounds), more than any other known terrestrial animal. Such results give it the most powerful bite of any fish in history, and only matched by a few animals, one of which was the “So it’s like a 20-foot-long fish, with huge teeth. The force of its bite was remarkably powerful: 11,000 pounds. Given that the T-Rex probably had an even bigger mouth, researchers wanted to know how it might have compared. 10 Lion – Bite Force : 650 psi.

I suspect the error lies in assuming an unrealistically small area over which the pressure is concentrated---dividing 8000 lbf by the 431000 PSI gives an effective area of just 12 square millimeters, but this is without taking into account the moment arm of the jaw. Tyrannosaurus rex had a bone-crushing bite with a force of 8,000 pounds. Due to their tooth structure, as well as bite marks found on Triceratops bones, the researchers suggest that the T-rex ate with a biting and chewing pattern, in the style of modern mammals like hyenas and wolves. The extinct sharks could bite with a force three times stronger than that of a T. rex - 105,000 to 171,000 Newtons - according to National Geographic. Tooth pressure is determined by how the shape of the teeth focuses the pressure into a smaller point, and the T-rex's long, cone-shaped chompers were perfect for piercing flesh and shattering bone. This feeding style is very different from modern crocodiles, which bite to kill before swallowing their meals mostly whole. "Having high bite force doesn't necessarily mean an animal can puncture hide or pulverize bone, tooth pressure is the biomechanically more relevant parameter," says Gregory Erickson, co-author of the study. Saltwater Crocodile. Not just mild steel---431000 PSI is well beyond the ultimate strength of the best maraging steels, and most other materials out there. Measurements of its jaw and analysis of its teeth suggested that its bite was up to 11 times as strong as that of a Tyranosaurus rex. The most powerful bite recorded from a living animal belongs to the saltwater crocodile For the largest sharks, the maximum bite force prediction was 18,216 Newtons. Channeling the force, a Tyrannosaurus bite could impart as much as 431,000 pounds per square inch (psi), which helped the animal pulverize the bones of … To give you some perspective, the average human can exert a force as great as 268 pounds per square inch (psi) using their molars.

"It was this bone-crunching acumen that helped T-rex to more fully exploit the carcasses of large horned-dinosaurs and duck-billed hadrosaurids whose bones, rich in mineral salts and marrow, were unavailable to smaller, less equipped carnivorous dinosaurs," says Paul Gignac, co-author of the study. It could bite and pull off off chunks of flesh and bone perhaps by pinning down the meat with its powerful back legs to get leverage, then swallow the chunks like a croc. The bite force generated by crocodiles is quite significant, and is comparable to the bite force produced by historic predators, such as the T. rex. There's not any real solid bite force numbers on this Theropod, though ive read that it most likely had a stronger bite than its close cousin Giganotosarurus which it self had a bite force of apoximately 3,100 pounds or just under a Sub Adult T.Rex and a possible maximum bite force of … 3 American Alligator – Bite Force : 2125 psi.
