Majungatholus was a very close reletive of Carnotaurus. Unlike Carnotaurus, Majungatholus was living in a tiny landmass that is now Madagascar. This forced Majungatholus to not only be an apex predator, but a cannibal as well. In 2003, a Majungatholus fossil was found with bite marks from another Majungatholus. This is the first positive proof that dinosaurs were occasionaly cannibals. Majungatholus is also very poorly known because there are barely any specimens to even work with. Some paleontologists think that the reason Majungatholus is so rare is the population in Madagascar was pretty small, and think about it: Tiny population+Small island=Disaster! The skull of Majungatholus has a very rough and bumpy texture. This suggests Majungatholus had an unusually hideous face. Some paleontologists think that hideous face could be a freak of nature. This dinosaur's ugly face could be the end result of inbreeding. The results of inbreeding can be pretty nasty. Inbreeding sideffects include less of a tolerence for disease, weaker bone structure, early death, and, maybe in the case of Majungatholus, mutations.
