Fossil fossils reveal new information about the migratory path of these plant dinosaurs.
An international team of archaeologists has described the discovery of a new dinosaur species in a new study. This is a new race Hatrosurride – Also known as the Duck Peak Dinosaur. The invention is very special. Because it provides new information about the mysterious migratory path of these animals.
The skeleton of the described Japanese dinosaur was discovered in 2004 by an amateur fossil hunter. He found bones in a 71- to 72-million-year-old sediment layer in a cement quarry on the Japanese island of Awaji. The excavated lower jaw, teeth, cervical vertebrae, shoulder bone and tail vertebrae were later transferred to the Japanese Museum, where they were on the shelf for some time before the researchers bent over the bones.
Now researchers are entering the business journal Scientific reports With their findings. This shows that the fossil bones belong to the previously mentioned goose-crane dinosaur. Dino is யமடோசரஸ் izanagii Mentioned (see box).
The genus name of the dinosaur refers to the ancient kingdom of Yamato, which includes the western Japanese archipelago. In Japanese mythology the species title refers to the god Isanaki and Isanami couple in Japanese mythology who are said to have created the eight lands of Yamato, the first land on the island of Avaji.
Duck-built dinosaurs are known for their wide, flattened moles. These plant dinosaurs lived in the late Cretaceous 65 million years ago, and their fossil remains have been found in North America, Europe, Africa and Asia. Duck crane dinosaurs have long been thought to have appeared in North America. They were then able to spread to South America and then reach Asia via a land bridge. From there they immigrated to Europe. But researchers are now coming to a new conclusion.
Discovery of the remains யமடோசரஸ் izanagii Refers to the migration of animals from Asia to North America with no other option. “Duck-peaked dinosaurs often used the Beringland Bridge to travel from Asia to present-day Alaska and then spread across North America,” said researcher Anthony Fiorillo. “When they roamed Japan, the country merged with the east coast of Asia. Tectonic activity separated the islands from mainland about 15 million years ago, long after the dinosaurs became extinct.”
This discovery explains an evolution in the way giant creatures moved. யமடோசரஸ் izanagii It distinguishes itself from other duck-crane dinosaurs by the development of its shoulders and forelegs. This gives us a unique insight into how duck-built dinosaurs evolved from two to four-legged animals.
Discovery யமடோசரஸ் izanagii Beacon not only provides important new information about dinosaurs. This raises new, intriguing questions about the existence of dinosaurs in Japan. Yamatosaurus Second new species only Hatrosurride Found in Japan. “In addition, these are the first dinosaurs discovered in Japan since the late Cretaceous,” said researcher Yoshitsu Kobayashi. “Until now, we did not know that dinosaurs lived in Japan at the end of the dinosaur era. The discovery of these Japanese models will help us understand how they migrated between different continents. ”
