Two quick headlines about monstrous jaw lines:

Dental Giant – Scientists in Utah dug up a new dino whose duck-bill encased hundreds of teeth. "At any given time, the dinosaur had over 300 teeth available to slice up plant material," reads the University of Utah statement. "Inside the jaw bone, there were numerous replacement teeth waiting, meaning that at any moment, this Gryposaur may have carried more than 800 teeth."

What a Pussy – Turns out a sabertooth tiger's growl was bigger than its bite. An analysis of the ancient cat's skull found that its chomp was three times weaker than that of a modern lion. The Australian paleontologists now think that the animal used its powerful neck muscles to drive those saberteeth like precision weapons into its prey. Contrast that with lions, which clamp down on windpipes (sometimes for a full 10 minutes) to suffocate victims.
