Majungatholus atopus

Majungasaurus (pronounced /məˌdʒʌŋɡəˈsɔrəs/ mah-jung-gə-sor-əs "Mahajanga lizard") is a medium sized genus of abelisaurid theropod dinosaur that lived in Madagascar from 70 to 66.8 million years ago, at the end of the Cretaceous Period. Only one species (M. crenatissimus) has been identified. This dinosaur was briefly called Majungatholus, a name which is now considered a junior synonym of Majungasaurus.


Like other abelisaurids, Majungasaurus was a bipedal predator with a short snout. Although the forelimbs are not completely known, they were very short, while the hindlimbs were longer and very stocky. 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. Other abelisaurids have different features: its larger cousin Carnotaurus had two large brow horns on its head, while some others, like Rugops, or Abelisaurus, lack the odd features on their skulls. It also had more teeth in both the upper and lower jaws than most abelisaurids.

Known from several well-preserved skulls and abundant skeletal material, Majungasaurus has recently become one of the best-studied theropod dinosaurs from the Southern Hemisphere. It appears to be most closely related to abelisaurids from India rather than South America or continental Africa, a fact which has important biogeographical implications. Majungasaurus was the apex predator in its ecosystem, mainly preying on sauropods like Rapetosaurus, and is also one of the the only dinosaurs for which direct evidence of cannibalism is known, along with Tyrannosaurus rex, although its' unknown if they actively cannibalized its own species or eat the injured and/or already dead specimen's corpses. When attacking Majungasaurus would bite and not let go, since its teeth curved backward and it had jaws made for gripping than slashing. Current size estimates put it around 8 metres at highest estimation. It was noted for cannibalism by BBC One documentary known as Planet Dinosaur. However, despite there's a high possiblity of cannibalism; as portrayed as active cannibals by most documentaries; it has to be stated, that it is unclear that if the fossil cases are an active cannibalisiation; akin to Modern Komodo Dragons; or Scavenging the dead/dying, similiar to most animals do today, including Humans in time of famines.

Misconception of "Majungatholus"

A braincase was gound beside a fossil remains of a Majungasaurus mistaken with the dome of a Pachycephalosaur. It was considered to be it's own genus until 1996 when a scientist compared it with the brow horn of Majungasaurus and after that it was crystal clear that Majungatholus remains were actually a brow horn of a Majungasaurus. Since then it is considered as the junior synonym of Majungasaurus.
