Scientists discover 240-million-year-old dinosaur that resembles a "mythical Chinese dragon"

A team of international scientists have discovered 240-million-year-old fossils from the Triassic period in China that one scientist described as a "long and snake-like, mythical Chinese dragon."

The 16-foot-long aquatic reptile, called Dinocephalosaurus orientalis, has 32 separate neck vertebrae – an extremely long neck, according to the National Museums of Scotland, which announced the news on Friday.

The new fossil has a snake-like appearance and flippers and was found in the Guizhou Province of southern China. 

Dinocephalosaurus orientalis was first identified in 2003 when its skull was found, but this more complete fossil discovery has "allowed scientists to depict the bizarre long-necked creature in full for the very first time." 

"It is yet one more example of the weird and wonderful world of the Triassic that continues to baffle palaeontologists. We are certain that it will capture imaginations across the globe due to its striking appearance, reminiscent of the long and snake-like, mythical Chinese Dragon," said Nick Fraser, keeper of Natural Sciences at National Museums Scotland. 

This fossil, as well as two previously discovered embryos of a similar creature, have helped scientist learn more about this type of creature, according to the study, published by Cambridge University Press. They lived in water and likely didn't need to venture on land to lay eggs.

The largest discovered skull of a Dinocephalosaurus orientalis is about 9 inches and its largest preserved tooth is about an inch. 

While the new fossil includes a poorly preserved skull, vertebrae, ribs and preserved limbs, the tail is missing. The vertebrae are "preserved in perfect articulation."

They also found at least four fish inside the abdomen, as well as small vertebrae and a possible limb bone, which could be an embryo or the remains of a small reptile the creature ate. 

Researchers from the U.S., U.K., China and Europe have been studying this creature for 10 years. "Among all of the extraordinary finds we have made in the Triassic of Guizhou Province, Dinocephalosaurus probably stands out as the most remarkable," said Li Chun, a professor from the Institute of Vertebrate Palaeontology and Palaeoanthropology.
