In the Gobi Desert in the Mongolian territory, the International Paleontologist team discovered the fossil of the previously unknown mammal species living during the Cretaceous period 100 to 66 million years ago. The new animal that resembled a mouse was called Ravjaa Ishiii in honor of the 19th century Dulduyytyn Danzaravzha and Japanese scientist Kenichi Icia’s Mongol Buddhist uterus. Published in İş Magazine ACTA Paleontologica Polonica (App).
In 2019, during the atonement of the Bainshire formation, scientists found a part of the lower jaw just one centimeter long. The analysis showed that the animal belongs to the Zhelestidee family, the ancient mammal of the Cretaceous period. However, the unique form of the jaw and high molars distinguishes it from other representatives of the group, which makes it possible to distinguish a separate genus and appearance.
This found the first Zhelestidae that changed the ideas about the spread of these animals in Mongolia: it was believed that they were mainly mainly in the coastal areas, but Ravjaa Ishiii proves that they had met deeply in the continental region.
The structure of the teeth indicates that the animal is fed by seeds and fruits overlapping with the brightest day of coated cheese plants. Thus, the discovery shows that early Eueries (ancestors of modern placental mammals) began to adapt to new environmental capabilities associated with floral plants.
“The broadcast process was postponed because of the pandemi, but now we are happy to show the scientific value of this small finding,” he said.
Professor Mototatak Saneoshi added: “Finding such a small fossil in a large desert is almost a miracle. A real gift from Gobi.”
Finding leads to new discoveries: scientists hopes that it will help to reclaim the picture of the old fauna of the Gobi Desert from the dinosaur times of more excavations.
Previously, scientists Close -up To solve a long climate of knowing.
