Dinosaurs researchers say that the newly identified T. Rex ancestors are a “missing link” between the APEX predator.

More than 85 million years ago, a smaller predecessor toured Tyrannosaurus Rex Mongolia plains. The dinosaur identity was unknown – so far.

in study Scientists were published on Wednesday in Nature, describing the new Tyrannosauroid selection called Khankhuulu Mongoliensis. Summit predator, including T. RexThe researchers said in the study that in the end, he originated from these smaller etiquette.

CBS News said: “This type, Khanshulu, is the lost link between smaller and smaller shapes and larger predators at the top,” said CBS News.

Zellingski said that the bone structure of Khancolo was discovered in Mongolia in the Jobi Desert in 1972 or 1973, but he did not study scientifically even a few years later. The remains are recognized by the AlexOurus Olsoni, another mysterious type. After identifying it, the bones became part of the museum collection and have not been relatively wiped for nearly 50 years.

The study found that these smaller predators referred to as Tyrannosauroids were medium -class, an evolutionary medium. During the period in which Khansulu lived in Mongolia, Tyrannosaurs began to grow more and take over the features of predators. It is not much known about these elaborating erection causes due to the remains of fragmented fossils, but researchers said that dinosaurs weigh about 1700 pounds. It was one of the largest predators in the ecosystem at the time.

“It is basically the direct grandfather of the Tyrannosaur family”.

Jared Fores, co -researcher of Calgary University, Jared Fores traveled to Mongolia a few years ago to search in different bones of the tyrants, and in this process, he achieved access to the bones of what they will determine later are the Khanblu.

Voris believed that the remains could be an important thing, as he often saw references to the popup, but after he began to examine bone, he knew that he could be a special thing. While studying the individual bone properties, one of the things he noticed was that the teeth of Khanchulu could not crush the bones, a distinctive feature of the predatory Tyrinosor the biggest summit.

“This animal had features that we have not seen before in more iconic Tyrannosaurses,” Forenes said.

Zelenitsky wrote from Mongolia that “I think it could be a new type.” Zelintsky said she replied, “I said, wonderful, keep looking at this so that we could make sure this is a new type.”

Pregnant scholars are not new to leading scientific discoveries – they had several. In 2023Zelenitsky was part of a team identified Tyrannosaurus with a meal in its stomach, and voris find out A new type of Tiranosuride dinosaurs, Thanatostristes Degrootorum – whose gender is translated into “Reaper of Death”.

“Re -writing a family history from Tyrannosaurs”

Zelintsky said this Asian news eventually crossed to North America using a northern land bridge between Alaska and Siberia. Dinosaurs have used these wild bridges, which have appeared periodically over the past 100 million years, to travel between Asia and North America.

And from it, these Tyrannosauroids developed and turned into a predatory predator. T. Rex is The most bloody predator land Ever to live, there was a long time magic with the dinosaur, which became extinct about 66 million years ago.

The authors participating in the study said that determining the new identity is still large discoveries that must be made in science. “What really started is to discover a new type that ended with a rewriting family history in Tyrannosaurss,” said Zellingski.
