According to recent findings, a newly discovered dinosaur could rewrite China's geological history.

The latest addition to the family of giant long-necked dinosaurs known as sauropods Lingwulong shenqi in the north of the country about 1

74 million years ago

At that time, East Asia was believed to be of the supercontinent Pangea separated.

But Lingwulong could be the proof that that was not the case.

Part of a subgroup called Nesauropods, which included Brontosaurus, Diplodocus, and Brachiosaurus, Lingwulong emerged right there it should not – in northern China, fifteen million years earlier than any other known dinosaur from this group.

Dr. Philip Mannion of Imperial College London, an author of the study, described the discovery as "twice as unexpected."

"It's not just the oldest member [of this group] it's the first one from Asia, and for a long time, it was thought that Neasacopods did not come to Asia during the Jura," he told BBC News [19659007] At the time, Pangea began shatter. It was suggested that a sea similar to the Red Sea, but larger, separated today's China from the rest of the supercontinent and prevented the animals from crossing.

"This suggests that [neosauropods] occurred before any other barrier entry, but increasingly the geological evidence suggests perhaps this barrier was rather ephemeral," says Dr. Mannion.

Despite Nea-sauropods in other areas of Pangea – now North America, Europe and East Africa – no older than 160 million years old

Lingwulong now occupies his place as the oldest known member of this family. But it could also show that these dinosaurs were in a much more advanced stage of evolution than previously thought – which caused their diversification from the middle to at least the early Jurassic.

Contrary to the notion that the dinosaurs have "failed." As a result of the Chicxulub effect, they died, and they were indeed very successful in evolving and adapting for many millions of years. They survived several mass extinctions on Earth caused by extensive volcanic activity and continued to evolve.

"This new Sauropod Lingwulong and the recent Ingentia – which is related to the origin of Sauropoda – show that dinosaurs from the beginning had an unusual ability to be anatomically innovative," says paleontologist English: German: emagazine.credit-suisse.com/app/art … = 120 & lang = DE

"This has enabled them to dominate and dominate in almost every terrestrial ecosystem over millions of years "Anatomical versatility" was probably one of the evolutionary keys that made her one of the leading vertebrates in the history of life on Earth, "she added.

The study was published in Nature Communications.
