Fossils suggest giant dinosaurs lived millions of years earlier than previously thought

Huge gentle giant dinosaur the size of a double decker bus discovered in Argentina

Scientists previously believed that giant dinosaurs didn't come into existence until 25 million years later.

According to scientists, Ingenia prima was the first dinosaur species to reach gigantism and even though it was a long way from the 70 tonnes (tons) that the biggest sauropods weighed from the end of the Cretaceous period (145-66 million years ago), the speed of bone tissue accumulation was greater than that of species from its era and the biggest giants that lived in Patagonia, in the south of Argentina.

Ingentia was an early member of a dinosaur group called sauropods that later included Earth's biggest terrestrial creatures including the Patagonian behemoths Argentinosaurus, Dreadnoughtus and Patagotitan.

Unlike later sauropods, Ingentia's legs were not pillar-like.

The dinosaur had an elongated neck and tail, and about 10m long.

Dinosaurs first appeared around 230 million years ago, and it was believed to have taken them about 50 million years to become massive. The first ones were modestly sized, a far cry from the huge dinosaurs of the subsequent Jurassic and Cretaceous Periods.

Ronaldo's transfer breaks Juventus' previous record, breaking the £75.3m they paid for Gonzalo Higuain from Napoli in 2016. In accordance with the request expressed by Cristiano Ronaldo , the club has agreed to a transfer deal with Juventus .

Sauropods were widely and wildly successful during the Jurassic period (199 million to 145 million years ago), and their appearance represents an important stage in the history of dinosaurs.

Ingentia prima was big - up to 32 feet (10 meters) long - but not almost as large as the massive titanosaurs that lived millions of years after it. It was at least twice as large as the other herbivores of the time'.

Dr Apaldetti said: 'Gigantism is an evolutionary survival strategy, especially for herbivorous animals'.

Reconstruction of Ingentia prima, a dinosaur from the Late Triassic period. It possessed a bird-like respiratory system, related to the development of air sacs inside the body that gave it large reserves of oxygenated air and kept it cool despite its large size. However, unlike the diplodocus and other later sauropod relatives, lessemsaurids stood on bent legs and had bones which grew in short, accelerated bursts.

The remarkably preserved specimens were discovered in a dinosaur "nest" unearthed at a World Heritage site known for its fossils in Argentina's north western San Juan province.
