About 90 million years ago, meat dinosaurs with teeth like sharks that stooped, hunting in the place are now Uzbekistan, according to a new study of the jaw bone of the giant 9: 00/2 : 26 Nou southern male giant shark teeth have lived in Uzbekistan 90 million years ago. 8 m long beast weighs 1,000 kg, longer than African elephants and heavier than the bison. Researchers named it Ulughbegsaurus Uzbekistanensis, named Ulugh Beg, a astronomer, mathematics, king of a territory (Uzbekistan today) in the 15th century. The researchers found that What makes them surprised is that this dinosaur is much greater (double and 5 times longer length) than previously known predators in its ecosystem: tyrant dinosaurs. The jaw bone was found in Uzbekum's Kyzylkum desert in the 1980s and the researchers have been discovered in 2019 in a collection of Uzbekistan Museum
. One of U. Uzbekistanensis's jaws show this animal belong to the carcharodontosaur family, or the dinosaur "shark teeth". These predators are cousins and competitors of tyrannical dinosaurs, the most famous species Tyrannosaurus Rex
Research Darla Zelenitsky, Associate Professor of Calgary University, said Two dinosaur groups are quite similar, but carcharodontosau dinosaurs are often slender and lighter than tyrant dinosaurs. Even so, the carcharodontosaurs dinosaurs are often greater than tyrannical dinosaurs, gaining weight greater than 6,000 kg. Later, about 90 million to 80 million years ago, meat-eating dinosaurs disappear and dinosaur tyrants developed in size, became a peak hunter in Asia and North America. Studiched researchers Italy, new discoveries are the first carcharodontosaur dinosaurs discovered in Central Asia. Biological houses knew that Timurlengia tyrant dinosaur lived at the same time and place. Uzbekistanensis is a peak predator in that ecosystem. The Chief of Research Group Kohei Tanaka, Associate Professor at the University of Environmental Sciences and Life at Tsukuba University, Japan, said: "Discover their I pointed out that the carnivorous animals are still dominant predators in Asia 90 million years ago. "The team found that Uzbekistanensis had unique bones above the teeth. However, it also has bone edges on both sides of the jaw similar to the 79.5 million-year-old tyrant dinosaurs Thanatotheristes degrootorum from Canada
