Rapetosaurus

Rapetosaurus was a sauropod dinosaur from Madagaskar that lived during the Late Cretaceous period. Its name means  'Krause's mischievous giant lizard'. Like other sauropods, it had long neck and small head on the top of it. An adult of Rapetosaurus was about 15 meters long. But it was still small  to be compared with such related titonosaurs like Argentinosaurus and Paralititan.

Most of the other sauropods, like the Brachiosaurus and Diplodocus, became died out in the early Cretaceous. The titanosaurs were the one exemption. They evolved on the southern supercontinent of Gondwana, and grew in information and diversity until they became the dominant herbivore of the late Cretaceous. Their time in power was cut short by the Cretaceous-Tertiary extinction event, which killed almost all the dinosaurs about 65 million years past.
