This dinosaur was the great predator before the T-Rex | Digital Trends Spanish

Until now, it is accepted that the Tyrannosaurus Rex has been the king of predators among the dinosaurs. But before the T-Rex there was another great dinosaur, the predecessor on the throne of the great predators and that was recently discovered by researchers at the University of Tsukuba: the Ulughbegsaurus uzbekistanensis.

This specimen lived 90 million years ago and the analysis of a fossil found in Uzbekistan – hence the name of the animal – reveals that it had a mass of more than 1 ton, while measuring between 7.5 and 8 meters long.

The Ulughbegsaurus belongs to the group of the carcharodontosauria, which were the largest predators existing before the emergence of tyrannosaurs. This group of dinosaurs also shared territory with other smaller tyrannosaurs, which at that time were predators of Second order.

The discovery of the Ulughbegsaurus is important for paleontology, because it will help to understand a little better what happened in the period between 80 and 125 million years ago. In that space, carcharodontosauria they were giving way can and disappearing, at the same time that the tyrannosaurs were bigger and bigger and became the maximum predator.

The reasons for this transition, which occurred in the so-called Cretaceous period, remains something of a mystery to scientists. And mainly, because there are not too many fossils that allow a more in-depth study of why the carcharodontosauria they began to disappear from the northern hemisphere.

Likewise, it is not known how tyrannosaurs became the predators par excellence, but there is a current of thought that believes that they managed to reach the top in the absence of competition. Although for now, that remains a mystery.
