Canada discovered a new flying dinosaur, about the size of a small plane

Flying dinosaurs (Pterizard) are the giants that occupied the sky during the dinosaur period, especially in the late Cretaceous, their size became increasingly large, but the number of species became smaller and smaller. . Canadian paleontologists recently discovered and named a new species of pterizard with a wingspan of up to 10 meters.

North America has always been considered an area of ​​rich fossil paleontological resources, and a large number of fossils have been found in the United States and Canada. Compared to dinosaur fossils, there are actually fewer Pterizard fossils found in North America, especially in Canada. It was not until 1972 that archaeologists uncovered several fossils of flying dinosaurs of the Azhdarchidae family in Alberta, Canada. This is the first time Pterizard fossils have been discovered in Canada.

Albert where found fossils.

At first, paleontologists thought that the fossils belonged to Quetzalcoatlus, a member of the family Azhdarchidae, a toothless pterosaur with long neck. Wingspan up to 10m, height 4.8 – 5.5m, weight from 210–250 kg. But paleontologist Michael Habib at the University of Southern California thinks these fossils come from an entirely new species of Pterizard.

Paleontologists are exploring fossils.

In 1992, paleontologists discovered a Pterizard fossil (number: TMP 1992.83) in the Dinosaur Park Formation Formation in Canada. Fossils consist of a skeleton after the skull, belonging to an immature individual. Later, paleontologists discovered many other fossils of this species, but most of them were small pieces and crumbled.

Pterizard fossils are found in Alberta.

Within 15 years, paleontologists have discovered numerous fossils of Azhdarchidae species in France, Hungary, Romania, Morocco and elsewhere. These fossils have provided many documents to study the biodiversity of the family Azhdarchidae. At the same time, paleontologists also had the opportunity to observe skeletal characteristics and measure fossils to better understand Quetzalcoatlus species.

Habib examined fossils discovered in 1992 while visiting the Royal Taylor Museum of Paleontology in Canada. From preserved fossils, paleontologists discovered many teeth marks on the surface, including teeth stuck in fossils. According to initial estimates, the teeth and tooth marks appeared after the pterosaur was dead and its owner belonged to a small Dromaeosaurus dinosaur.

When comparing the vertebrae discovered with Quetzalcoatlus, paleontologists determined that their anatomical characteristics were completely different and that they clearly represented two different species. According to the Pterizard fossils discovered in 1992, paleontologists speculated that its wingspan reached 5 meters, but another fossils kept in the museum (TMP number 1980.16.1367) were sized. bigger ruler. Because the process of preserving these fossils is still unclear, many of those fossils were originally thought to belong to the leg bones, but research shows they are ancient vertebrae of this species. , with a length of about 0.5 meters. According to this fossil, the wingspan of this new Pterizard reaches 10.5 meters.

The fossil was mistakenly fossilized from the femur.

Image recovery of the new species Pterizard with wingspan longer than 10 meters.

In September 2019, paleontologists published a study in the Journal of Vertebrate Paleontology, entitled “Cryodrakon boreas, gen. Et sp. Nov., A Late Cretaceous Canadian azhdarchid pterosaur”. and named the new species Cryodrakon boreas.

In it, “Cry” in ancient Greek means icy, cold and “drakon” means dragon. Cryodrakon means ice dragons, representing fossils found in cold weather like Canada. “Boreas” means northern, also means cold.

The Dinosaur Park Formation Formation, which discovered the fossil of this new flying dinosaur, belonged to the Late Cretaceous period, from 76.7 to 74.3 million years ago. The fossilized specimen of the Cryodrakon boreas was found on the lower edge of the formation, which means the species dates back about 76 million years.

Dinosaur Park Formation is another large formation. The dinosaurs found in this formation are also very rich and abundant, including Hesperonychus, Dromaeosaurus, Caenagnathidae, Micropachycephalosaurus, …

With a wingspan of more than 10 meters, Cryodrakon has a pointed tip, slim neck, and webbed wings that can soar into the blue sky with the help of hot air. Paleontologists believe that Cryodrakon mainly ate fish, but they also ate small animals and dinosaurs. When standing on the ground, the adults possess a height of up to 4 meters.

Cryodrakon is a genus of Azhdarchid Pterizard living in the late Cretaceous period in present-day Canada. It contains a unique species, Cryodrakon boreas.
