A new species of pterosaur, a flying reptile, has been identified in the vast, dry terrain of Canada’s badlands. On Tuesday, it was anointed as “Cryodrakon boreas,” Greek for “Frozen dragon of the north wind.”

The discovery may sound like something out of Westeros (who can forget Jon Snow, beleaguered king in the north, riding Rhaegal over the icy wilderness?) but “Game of Thrones” fans shouldn’t get too excited: According to researchers, Cryodrakon looked less like Daenerys Targaryen’s fire-breathing dragons than it did a giraffe-sized, reptilian stork.

The carnivorous animal lived in modern-day Alberta during the Cretaceous period around 77 million years ago, according to a study in the Journal of Vertebrate Paleontology. It could grow to about 13 feet tall, with a wingspan of up to 30 feet, making it one of the largest flying animals ever. It had no chewing apparatus, so it would probably eat whatever was small enough to go down its gullet, including lizards, mammals and baby dinosaurs.

Like other pterosaurs, the Cryodrakon had quite awkward proportions, with a long neck, huge wings and a slender head about 3.5 times the length of its body. As one expert said, imagine a “giant flying murder head.” Alternatively: “A pair of wings that carry around a big head for guzzling things.”

Man, 30, shot in Donaghmede, north Dublin Emergency services raced to the scene after the 30-year-old was shot at a house on Streamville Road in Donaghmede. The man was taken to Beaumont Hospital in a serious condition, Dublin Live reports. A garda spokesperson said: "Gardaí are at the scene of a shooting incident that occurred at approximately 7.10pm today, Friday, 6th September 2019, at a house on Streamville Road in Donaghmede, Dublin 13. "A 30 year old male sustained a number of gunshot wounds and was taken to Beaumont Hospital in a serious condition. "The scene is currently preserved. Investigations are ongoing.

Called the " frozen dragon of the north ," a new species of flying dinosaur, Cryodrakon boreas, has been discovered in Canada. The first fossil remains were actually discovered 30 years ago at Dinosaur Provincial Park in Alberta, Canada Cryodrakon boreas lived about 77 million years ago .

An updated analysis of a 77 - million - year -old fossil found in Alberta, Canada has The authors of the new study chose the name Cryodrakon boreas, which means “cold dragon of the north winds .” A dragon indeed; this creature boasted a wingspan measuring over 10 meters (32 feet) in length, and it

Researchers said that while the pterosaur’s new name was more inspired by Alberta’s frigid landscape than it was by “Game of Thrones,” they were aware that it might elicit some comparisons.

(David Maas) “Yes, we had a good, personal chuckle about that,” said Michael Habib, a paleontologist at the University of Southern California and a fan of the show.

François Therrien, curator of dinosaur paleoecology at Alberta’s Royal Tyrrell Museum of Paleontology, noted that while modern-day Alberta is known for its harsh winters, the landscape that the Cryodrakon would have soared over in the late dinosaur age would actually have been a tropical paradise near a large inland sea.

The fossils that were used to establish the Cryodrakon’s holotype — a single specimen upon which the new species is established — were discovered some 30 years ago in Alberta’s Dinosaur Provincial Park, known for being one of the richest sources of dinosaur fossils in the world. Until recently, however, the remains were thought to belong to an already known species of pterosaur, called the Quetzalcoatlus, first found in Texas.

The flying reptile had a wingspan of at least 16 feet and may have grown to a wingspan of up to 33 feet, dominating the skies above North America about 75 million years ago . The creature, called Cryodrakon boreas or Frozen Dragon of the North Winds , is similar to the largest known pterosaurs

Habib, one of the few scientists in the world who has worked extensively with Quetzalcoatlus fossils, said that when he first saw the Canadian pterosaur four years ago, he had a hunch that it was not what he had seen before. While its neck bones were long like a typical Quetzalcoatlus, its proportions did not match up.

He enlisted the help of David Hone, a specialist in pterosaur taxonomy, the classification of organisms, who realized that the remains in Alberta were exceptionally well preserved. The skeleton that researchers worked with consisted of parts of the animal’s wings, legs, neck and rib — a remarkable sample, he said, given that the bones of these types of reptiles tend to be thin and fragile, causing them to disintegrate over time.

“This type of pterosaur [azhdarchids] is quite rare, and most specimens are just a single bone,” Habib told SciTech Daily. “Our new species is represented by a partial skeleton. This tells us a great deal about the anatomy of these large fliers, how they flew, and how they lived.”

North Korea fires projectiles after offer to resume talks with US

North Korea fires projectiles after offer to resume talks with US North Korea has launched at least two unidentified projectiles just hours after it offered to restart nuclear talks with the US. The projectiles, which were fired toward the sea, are believed to have been used as a ploy to pressure the US into making compromises in negotiations it wants to schedule for the end of the month. It is understood that North Korea is willing to offer partial denuclearisation in return for the US providing security guarantees and the lifting of crippling sanctions - a proposal that led to the latest talks in February falling apart.

The cryodrakon boreas – or ' frozen dragon of the north wind ' -- is seen in this artist's rendering. One of the largest creatures ever to fly on this planet had a wingspan about the length of a school bus and They would have lived in the region about 76.6 million years ago during the Cretaceous period.

The discovery of Cryodrakon means North America was home to at least two genera of large azhdarchids, expanding our To recognize the modern climate in the region where this pterosaur once roamed, they named the new pterosaur Cryodrakon boreas, or “the cold dragon of the north winds .”

Hone had a “Eureka moment” early on when he discovered a particular pattern of holes in the fossils that seemed unique, but it took him and the other researchers several years more to cross-check the specimen with pterosaur remains in Mongolia, France and elsewhere to confirm that this was a new species, he said.

Now that they have, however, the possibilities for future research are expansive, Therrien said.

“I tell my students all the time, taxonomy is the most fundamental bit of biological science,” said Hone, director of the biology program at Queen Mary University of London. “If you don’t know what species you’ve got, how do you know what else is going on?”
