The strongest bites in the animal kingdom

[Polar]

Does anyone have any data on the bite forces of dromaeosaurs/raptorids such as Utahraptor or Deinonychus, other than the one I provided below? With their muscular jaws and thick, yet sharp-ass teeth, these dromaeosaurs look like they can put most modern carnivores down in shame regarding bite force.

Does Deinonychus really have one of the most powerful bites of all dinosaurs?

"Experiments with modern cow bones suggest [i]Deinonychus needed a whopping 8200 N to puncture Tenontosaurus bones to the degree seen in the fossil remains. This value puts Deinonychus bites on par with those of adult alligators and leaves hyenas in the biomechanical dust."[/i]

" Therrien et al. (2005) estimated [i]Deinonychus bite force at a relatively wimpy 15.7% of alligator jaw power, which Gignac et al. translate into 1450 N. This isn't unimpressive - as strong as that of a 30 kg wolf - but a far cry from an alligator-like bite, and certainly deflates our reconstructed jaw muscles to their traditional size."[/i]
