Сонирхолтой баримтууд
Majungasaurus lived about 70 to 66 million years ago, during the very end of the Cretaceous Period. It was one of the last non-avian dinosaurs before the big extinction.1
This dinosaur had a thick, bumpy skull with a single rounded horn on top of its head. The horn was made of bone and was probably used for head-butting or showing off.12
Majungasaurus was about 6 to 7 metres long, which is as long as a big school bus. It was a medium-sized theropod, not as huge as T. rex but still a fierce hunter.2
Fossils show that Majungasaurus sometimes ate other Majungasaurus. Tooth marks on its bones match its own teeth, making it one of the few dinosaurs known to have been cannibalistic.2
It shared its home with many other animals, including the long-necked sauropod Rapetosaurus, the small meat-eater Masiakasaurus, and giant crocodile-like creatures.1
The first Majungasaurus fossils were found in 1895 by French explorers. At first, scientists thought it was a kind of Megalosaurus, and later it was even called Majungatholus.12
Majungasaurus is one of the best-known meat-eating dinosaurs from the southern continents. Many complete skulls and skeletons have been found, so scientists know a lot about it.2
