Saber-toothed cats living in North America up to 10,000 years ago relied on a strong pounce and a swift bite to kill their prey.

Instead, says Colin McHenry of the University of Newcastle in Callaghan, Australia, saber-toothed cats probably tackled prey and used their prominent canine teeth to pierce a victim's airway.
