Here, we estimate the bite force of Zygophyseter varolai, a macroraptorial physeteroid from lower upper Miocene strata of the Pietra leccese formation (Apulia, Italy) using the finite element analysis (FEA). (researchgate.net)
In vitro bite forces have been estimated by calculation of the force produced using mechanical equations representing the jaw adductor muscles and of the mandible and skull structure Bite force can be estimated in silico using finite element analysis of the computed model of the anatomical structures.

Jaws10
Neither its bite force, nor how such force might be delivered using relatively elastic cartilaginous jaws, have been quantified or described. (researchgate.net)
We have digitally reconstructed the jaws of a white shark to estimate maximum bite force and examine relationships among their three-dimensional geometry, material properties and function. (researchgate.net)
Although the shark's cartilaginous jaws undergo considerably greater deformation than would jaws constructed of bone, effective bite force is not greatly diminished. (researchgate.net)
Although brown bears ( Ursus arctos ) primarily eat salmon and berries, they have some pretty huge jaws - and a bite to match. (yahoo.com)
In addition - also relative to weight - its jaws are slightly shorter, which increases the leverage for biting. (yahoo.com)
The second category includes problems associated with deviations in the anatomical structure and position of the jaws - their correction requires the use of more radical medical techniques due to the pathology's complexity. (how2wish.com)
The bite force variation is tied to differing jaw shapes and tooth forms, that's why the Bull Terrier makes a good candidate with his muscular large jaws. (terrierology.com)
Do Bull Terriers lock their jaws when they bite? (terrierology.com)
However, this only shows how strong their bite actually is and has nothing to do with their jaws doing something abnormal. (terrierology.com)
Bull Terriers have an intimidating muscular look with large jaws, the almond eyes take away from them the big-eyed happy dog look, add to that their strong bite force and it's understandable to be worried. (terrierology.com)

What Is the Strongest Animal Bite in the World? (yahoo.com)
Even though the jaguar doesn't have the overall strongest bite in the big cat family, we still wouldn't want to get caught in those chompers. (yahoo.com)
With all those pointy teeth, what is the strongest animal bite in the world ? (yahoo.com)
Based on available data, here are the animals with the 10 strongest bite forces in the animal kingdom. (yahoo.com)
According to a 2005 review of biting mammals , the gray wolf ( Canis lupus ) has the strongest bite of any canine, at 593 Newtons. (yahoo.com)
While the jaguar may have the strongest bite for its stature, the tiger proves size does matter (when it comes to bite strength). (yahoo.com)
A 2012 study published in The Anatomical Record compared nine species of big cats to find that, while the tiger had the strongest bite force, the jaguar ( Panthera onca ) had the biggest bite for its size. (yahoo.com)
The Bull Terrier bite force was never tested accurately, it was estimated to be around 250 PSI based on the shape of his jaw and his strongly built muscular body, making him on the list of the strongest 15 dog bites. (terrierology.com)
Species4
We predict that bite force in large white sharks may exceed c. 1.8 tonnes, the highest known for any living species, and suggest that forces may have been an order of magnitude greater still in the gigantic fossil species Carcharodon megalodon. (researchgate.net)
thus allowing for robust comparisons of bite force values in these marine predator species. (researchgate.net)
No animal has ever registered the same results for two bites, which shows that these measurements are never accurate but will give a roughly close idea about the bite force of the species. (terrierology.com)
The difficulty of the bite force testing is why these tests are not conducted on most dog breeds, but research was done by computers analyzing jaw from and muscles have abled scientists to give an estimate of the bite force for multiple species. (terrierology.com)
Stronger bite2
Although the lion ( Panthera leo ) is slightly smaller than the tiger, it has a stronger bite (1768 N), according to a 2005 review . (yahoo.com)
Multiple tests have been conducted on multiple animals that carried for years the label of worst bites, but surprisingly the results have shown that size and aggression are not synonymous with a stronger bite force. (terrierology.com)
Arrangement2
Hartstone-Rose explained that "the strength of the jaguar's bite is due to the arrangement of its jaw muscles, which, relative to weight, are slightly stronger than those of other cats. (yahoo.com)
The correct ratio of the upper and lower rows is characterized by tight contact of the antagonists, a small (no more than a third of the height of the crowns) overlap, and a natural anatomical arrangement of the elements. (how2wish.com)
Estimate3
Some animals are too rare or dangerous for this type of invasive testing, so scientists have come up with another method: computerized models of an animal's skull and jaw muscles that estimate its bite force. (yahoo.com)
The truth is, most bite force data is simply an estimate, whether it comes from a computer model or from wild animals biting down on a device. (yahoo.com)
There are actually two ways to measure the bite force pressure of the Bull Terrier and any other animals but it remains at best an estimate. (terrierology.com)
Fossil1
Back in 2004, I was excited to read the new story of an ancient genetic change that might explain anatomical changes in fossil hominins. (johnhawks.net)
World's1
But you can't simply ask the world's toughest predators to bite down on the same instrument, so it's hard to control for outside variables. (yahoo.com)
Predators1
Our FEA simulations indicate that Z. varolai exerted an anterior bite force of more than 4000 N and a posterior bite force of more than 10000 N. These values are similar to those estimated for other marine predators known for their powerful bite. (researchgate.net)
Calculation1
Consequently, doing the same calculation with the Z. varolai bite force at 20° would produce misleading data. (researchgate.net)
Skull1
In this scenario, mechanical forces on the skull once held back the evolution of brain size in early hominins. (johnhawks.net)
Muscles4
To explore multiple bite scenarios, we set four different load cases on a 3D model of the cranium obtained via digital photogram-metry, considering the temporalis and masseter muscles as jaw adductors. (researchgate.net)
Other primates express this gene in their jaw muscles, where it strengthens the bite force. (johnhawks.net)
There are other tests that are performed on sedated animals by electrical stimulation of jaw adductor muscles, but this may not be reflective of volitional bite force during natural activity. (terrierology.com)
Humans1
The real danger of a dog bite is not when he bites down on something and refuses to let go, but instead when he shakes his head and that's when you can expect more damage, but this is very unlikely with Bull Terriers, they are not likely to bite humans. (terrierology.com)
Structure1
Bad habits are characteristic of children - the anatomical structure is affected by the constant sucking of a pacifier or fingers, attempts to gnaw on hard objects, tongue pressure on growing units, and even a curvature of posture in a sitting position. (how2wish.com)
Maximum1
Three and six months after each overdenture was inserted, clinical performance in the form of maximum biting force was evaluated. (hindawi.com)
Data1
It's possible the polar bear has a bite force even stronger than the brown bear's, but peer-reviewed data is lacking. (yahoo.com)
Study1
For context, a 2014 study found the average human bite force is 149-354 N, depending on age and sex. (yahoo.com)
Pressure1
Bite force is the pressure an animal exerts when it bites down, and the SI unit for bite force is the Newton, or kilogram-meters per second squared. (yahoo.com)
Compare1
But is it fair to compare an estimated bite force to a physical demonstration of a bite? (yahoo.com)

In a 2005 review of mammal bites , the brown bear - which includes the grizzly bear and the giant Kodiak bear - had the highest bite force of any bear at 751 N. (yahoo.com)
Hard4
Three-dimensional computer analysis of white shark jaw mechanics: How hard can a great white bite? (researchgate.net)
Testing the bite force of a Bull Terrier or any animal for that matter is not as simple as simply asking the dog to bite as hard as he can. (terrierology.com)
Most animals, dogs included adjust their bite force to every situation, that's why it is hard to get a clear reading of their true bite force. (terrierology.com)
The closest scientists have gotten is simulating a situation in which the animal needs to bite hard, and measuring that bite force in that particular situation. (terrierology.com)
Device1
These are tests performed on living animals, often times the animal is conscious and in a situation where he's lured to bite a target that has a testing device on it. (terrierology.com)
Size1
When those forces were relaxed by reducing the jaw musculature, brain size was free to increase. (johnhawks.net)
Simply1
Bull Terriers and all dogs have no kind of locking mechanism that will prevent it from opening, they simply have a strong bite. (terrierology.com)
Powerful1
The spotted hyena ( Crocuta crocuta ) has a bite force of 773 N - more powerful than a bear, according to this review of mammal bites . (yahoo.com)
Dogs1
This misconception of dogs locking their bite is caused by the fact that they can bite onto something and hold it for a long time and you've probably observed this behavior playing with your dog. (terrierology.com)
List1
Though hyenas are relatively small compared to other animals on this list, their hefty bite allows them to easily chow down on prey such as the giraffe in the background. (yahoo.com)
Animal2
In recent years, increasingly more dog owners are interested in knowing the bite force of their beloved four-legged friends, especially with the tests that have been introduced to the animal kingdom by scientists and documentary filmmakers. (terrierology.com)
The testing is like dragon slaying by committee, often involving ten or more people to test a single animal," said Erickson, of Florida State University when testing the bite force of the saltwater Crocodile. (terrierology.com)
