Lebitso le bolela: “fears nothing”1
E jele: DimelaMelala e meleleleKretase ya Morao

Dreadnoughtus was a giant, long-necked plant eater that stomped through ancient Argentina. It was one of the biggest land animals ever found, and its name means 'fears nothing' because it was so huge and tough.1

1

Dreadnoughtus is known from more complete skeletons than any other gigantic titanosaur, with about 70% of the bones behind the skull preserved.13

2

Its neck was super long, about 11.3 metres (37 feet), which is almost half of its total body length.1

3

The type specimen was still growing when it died, so adults might have been even bigger.1

4

Its bones were buried quickly in a flood, which is why they are so well preserved.1

5

Small theropod teeth found with the bones suggest scavengers, maybe megaraptorans, nibbled on the carcass.1

6

Dreadnoughtus lived about 76 to 70 million years ago, during the Late Cretaceous.1

Dipotso tse botswang haholo ka Dreadnoughtus

?How big was Dreadnoughtus?

About 26 metres long and weighed around 48 to 49 metric tons, though some estimates range higher or lower.14

?What did Dreadnoughtus eat?

It was a plant-eater (herbivore). Its long neck helped it reach lots of different plants without moving much.51

?Was Dreadnoughtus bigger than T. rex?

Yes, Dreadnoughtus was much bigger. It was about 26 metres long and weighed up to 49 metric tons, while T. rex was about 12 metres long and weighed around 8 metric tons.15

?Did Dreadnoughtus have any predators?

Healthy adults were probably too big to be attacked, but small theropod teeth found with the bones suggest scavengers like megaraptorans nibbled on the carcass.15

?How fast could Dreadnoughtus run?

Nobody knows for sure, but because it was so huge and walked on four legs, it probably moved slowly, like a modern elephant.5

?Where was Dreadnoughtus found?

In Patagonia, Argentina, in the Cerro Fortaleza Formation of Santa Cruz Province.14

?When did Dreadnoughtus live?

It lived during the Late Cretaceous, about 76 to 70 million years ago.15

?Why is it called Dreadnoughtus?

Its name means 'fears nothing' because its huge size made it hard for predators to attack. It also honors the dreadnought battleships.15

Mosenyi wa ditshomo

Tshomo: Some people think Dreadnoughtus was the biggest dinosaur ever.

Nnete: It was one of the largest known from fairly complete remains, but other titanosaurs like Argentinosaurus might have been heavier, though they are known from much less complete fossils.1

Paleontologist Kenneth Lacovara discovered Dreadnoughtus in 2005 in the Cerro Fortaleza Formation in Argentina. It took four summers to dig out the huge bones, using mules and ropes to move them.1
E sa ntse e phehwa kgang
Scientists still debate exactly where Dreadnoughtus fits in the titanosaur family tree, because it has a mix of advanced and primitive features.1
