It would be nice to see a source of who did the 5000psi measurement of the Nile croc bite.

Paleobiologist Gregory M. Erickson and colleagues put all 23 living crocodilian species through an unprecedented bite test. The "winners"—saltwater crocodiles—slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force.

"We tested several 17-foot [5-meter] saltwater crocs," he said. "If you scale the results up to 20-footers, you get estimates of 7,700 pounds [34,250 newtons], which is the low end of T. rex bite-force estimates.
