Rapetosaurus

O nome significa: “Rapeto lizard, after a giant deity in Malagasy folklore”1
Comía: PlantasPescozos longosCretáceo Superior

Rapetosaurus was a long-necked, plant-eating dinosaur that lived on the island of Madagascar. It was one of the last giant sauropods, but it was smaller than its huge cousins like Argentinosaurus. A nearly complete skeleton of a baby Rapetosaurus helped scientists learn a lot about how titanosaurs grew.1

Datos curiosos

1

Rapetosaurus is the most complete titanosaur ever found, with a skull still attached to its body.1

2

A baby Rapetosaurus weighed only about 3.4 kilograms (7.5 pounds) when it hatched, but could grow to over 10 tonnes as an adult.1

3

The young Rapetosaurus probably did not need its parents to survive, but it may have starved during Madagascar's harsh dry seasons.1

4

Rapetosaurus lived alongside the fierce predator Majungasaurus, which may have hunted it.1

5

Unlike many other titanosaurs, Rapetosaurus shared its home with only one other large plant-eater, another titanosaur.1

As preguntas máis frecuentes sobre Rapetosaurus

?How big was Rapetosaurus?

Rapetosaurus reached about 15 metres (49 feet) long as an adult, and one estimate put a probable adult at 16.5 metres (54 feet) and 10.3 tonnes (11.35 short tons). A juvenile measured 8 metres (26 feet) long and weighed about as much as an elephant.1

?Was Rapetosaurus bigger than T. rex?

Rapetosaurus was longer than Tyrannosaurus rex, reaching about 15 metres (49 feet) compared to T. rex's roughly 12 metres (40 feet), but the sources do not directly compare them.1

?Did Rapetosaurus have feathers?

No, Rapetosaurus was a sauropod dinosaur, and sauropods did not have feathers. The sources do not mention feathers.1
