Bite force study reveals extinct dino-eating 'Pacman' frog

A study of the bite force of South American horned frogs has revealed that its now-extinct ancestor which lived about 68 million years ago in Madagascar likely ate small dinosaurs. The horned frogs, dubbed "Pacman" frogs for their round shape and large mouth, similar to the video game character Pac-Man, generated a 3-kg bite force using a 4.5-cm head width.
