Tyrannosaurus bite was world's strongest

Scientists believe Tyrannosaurus rex had the strongest bite of any creature that ever lived.
Researchers used a laser scan of a Tyrannosaurus fossil to pinpoint the jaw muscles and to map pressure sensors on the skull to calculate the amount of force the jaws could bite down with. What they found was that the maximum force of the back teeth was between 30,000 and 60,000 Newtons, the equivalent of having a medium-sized elephant sitting on you.
Dr Bill Sellers, who studies the physical capabilities of living and extinct animals at the University of Manchester, told BBC Nature: "I think everyone expected T. rex to have a strong bite force, but it's even stronger than we expected. "

It amazes me how these guys come up with these theories,how do they know when there is nothing to compare with ?.We know that they were pretty nasty in their day,but was there not a much bigger predator that was discovered a while ago,maybe that had the strongest bite,so now these scientist chaps will be having an arguement as to which was the greatest.Oh well as long as it keeps them out of mischief,like trying to discover a cure for diseases etc,and doing something USEFULL instead of something which the average citizen does not care about,enough said....

Gets confusing. One minute these things are slow, scavengers. The next, top speed predators. Its not as if there tonnes of new evidence being dug up every day. I suppose they have to spend the grant of something

I do laugh at the comments on "They could be doing something useful" - Well yes, but that would require another 5 years of studying at University/College.... Palaeontologists and archaeologists are not medical doctors, they do not have such degrees, therefore they cannot research diseases. Stuff like this has to be researched, stuff isn't black and white related to something. Just like you wouldn't think biology has anything to do with space travel, but it does. Same rules apply here. At least they've got a job and are contributing stuff to the scientific community. If it was not for the study... [More]

Jerky was tough in those days so it probably needed that three tonne bite. (shame about those wee arms though... lol)

Maybe my math is off, but this isn't nearly as interesting as they make it sound to me. 30,000-60,000 newtons is about 3.0-6.0 tonne. Granted it IS an increase, but according to this article, back in 2008 we were estimating a 3 tonne bite force on the T-rex already. And much higher on the Megalodon, around 18 tonne. http://scienceblogs.com/notrocketscience/2008/08/prehistoric_great_white_shark_had_strongest_bite_in_history.php It also says a modern white shark can exert a 1.8 tonne bite. ::edit:: I'm thinking those numbers are wrong though, and perhaps the shark article as well. Stupid convers... [More]
