Nature Millions of years ago, this "frozen dragon" flying reptile, as mountainous as a fighter jet flew over Earth – My Blog

Scientists report that they had a chance considered one of the many ideal flying animals to understand ever lived – a large and fearsome reptile that ruled the heavens over 70 million years ago at the end of the Cretaceous period.

Nicknamed Cryodrakon boreas, which roughly translates to "frozen north wind dragon," the now extinct predator had a wingspan of up to 10 meters or about 33 feet. There are approximately three conditions of the ideal rooster size of the currently living sector, the wandering albatrossand the size of one F-16 fighter jet.

Undoubtedly, one of several species of extinct flying reptiles, commonly known as pterosaurs, was one that sought animals irregularly.

"They have a rough estimate of giraffe," said David Hone, director of the biology program at Queen Mary University in London and lead creator of an article on the discovery published September 9 in the Journal of Vertebrate Paleontology. "If you were standing next to a giraffe in a zoo and you stretched your face about twice as often and screwed more finger joints into the entrance legs, you would usually buy it. They had large heads, large necks, and long, thin bodies." covered by an elegant, downy feathered esteem found in baby birds.

Cryodrakon is believed to weigh over 200 kg in a method of over 440 pounds. Tiny is known for its coloration, although an illustration reveals a white animal with a purple spot on its aid that seems a bit small to estimate a maple leaf.

The shadow and shape of the spot had been chosen in half to recognize that extinct fossils to name the species had been found in Canada, however, Hone referred to as the fanciful look at the "perfectly plausible" shadow plot for Cryodrakon.

Hone talked about Cryodrakon, undoubtedly lived his lifestyle immensely in the background, walking with spherical esteem as much as heron or heron and feeding on lizards, tiny mammals and infant dinosaurs – “close to anything sufficiently tiny. to suit your throat. "

However, it was moreover a talented pamphlet, presumably in a position to deplete its membranous wings to fly immense distances. "A race of hundreds and even thousands of kilometers should not have been a mountainous deal," said Hone. "I wouldn't be stunned anymore if it happened in a large part of the northern United States."

The fossilized remains extinct to save the discovery had long been found in Alberta. Scientists had long believed that the fossils belonged to each other. monumental species of pterosaurs, commonly known as Quetzalcoatlus.

In a course he described as extremely laborious, Hone and his collaborators took a close look at fossils and other compounds over time and the trajectory that they were totally different from Quetzalcoatlus to symbolize a totally different species.

Not everyone is convinced that recent analysis is especially critical. "It describes some recent topics and names a species, but it does not greatly alter our concept of evolution or diversity of pterosaurs," S. Christopher Bennett, professor of biological sciences at Citadel Hays Inform University in Hays, Kansas, and an expert on pterosaurs, we spoke in an email.

However, Brent Breithaupt, a paleontologist at the Bureau of Land Management in Cheyenne, Wyoming, offered an unknown overview. The recent finding "provides additional insight into the prehistoric past and allows us to better understand the lifestyle and conditions of the animals living with the dinosaurs, especially those that were flying in the skies," he said by email.

"One has to marvel at the totally different unknown and scientifically crucial specimens that still need to be found in museum collections and spherical outcrops in the sector," he added. "There is an incessantly recent thing to discover in paleontology."
