Majungatholus was a theropod dinosaur that lived on the island of Madagascar 70 million years ago. Reaching 10 meters in height, with sharp, spike-like teeth, this animal may have been pulchritudinous but was certainly not nebbish in character. A group of scientists recently discovered evidence that the majungatholus was not just a big meat eater, but a cannibal. Teeth marks on bones of Majungatholus found in Madagascar were matched to Majungatholus' teeth. This finding marks the first solid proof of cannibalism in dinosaurs.
