About Majungasaurus
Majungasaurus (; lit. 'Mahajanga lizard') is a genus of abelisaurid theropod dinosaur that lived in Madagascar from 70 to 66 million years ago, at the end of the Cretaceous Period, making it one of the last-known, non-avian dinosaurs that went extinct during the Cretaceous–Paleogene extinction event. The genus contains a single species, Majungasaurus crenatissimus. This dinosaur was also called Majungatholus, which is considered a junior synonym of Majungasaurus.
Like other abelisaurids, Majungasaurus was a bipedal predator with a short snout. Although the fore limbs are not completely known, they were very short, while the hind limbs were longer and very stocky. Measuring around 7 m (23 ft) long and weighing more than 1 t (1.1 short tons), it can be distinguished from other abelisaurids by its wider skull, the very rough texture and thickened bone on the top of its snout, and the single rounded horn on the roof of its skull, which was originally mistaken for the dome of a pachycephalosaur. It also had more teeth in both its upper and lower jaws than most abelisaurids.
