While as massive as a bull African elephant, Mansourasaurus was modestly sized next to titanosaur cousins such as South America's Argentinosaurus
, Dreadnoughtus and Patagotitan and Africa's Paralititan, some exceeding 100 feet (30 meters) long.
Titanosaurs are famous for including the largest land animals known to science such as Argentinosaurus
, Dreadnoughtus and Patagotitan.
shahinae was a titanosaur, the group of dinosaurs that include the biggest of them, like Argentinosaurus
, Dreadnoughtus, and Patagotitan.
A comparison of the backbones shows that this creature was 10 per cent larger than previous recordholder, the Argentinosaurus
At the length of four double-decker buses, it's 10 per cent bigger than an Argentinosaurus
- the previous largest dinosaur known.
Cox adds: "The great dinosaurs like diplodocus and argentinosaurus
existed on the limit of bone strength, and would have been in extreme peril if they fell over.
These include the curious Dilophosaurus, fearsome Gorgonops and two of the biggest, towering at eight metres tall, the Apatosaurus (25 metres long) and Argentinosaurus
Its calculated 77-tonne weight would have made it as heavy as 14 African elephants, beating the previous record holder, Argentinosaurus
, by some seven tonnes.
According to the researchers, the animal was 40m long and 20m tall and weighed 77 tonnes, being as heavy as 14 African elephants, and seven tonnes heavier than Argentinosaurus
, the BBC reported.
Although there are dinosaurs that are larger, Argentinosaurus
for example, these species are known from only a few bones.
The huge Argentinosaurus
who weighs in at a massive 75,000kg is threatened only by the equally huge Mapusaurus that lurks in the greenery and hunts in gangs.
Visitors immediately will encounter the enormous head of an Argentinosaurus
, considered the world's largest sauropod.
