The world of dinosaurs has always been a source, almost inexhaustible, of studies. The discoveries of new fossils have been fundamental to know more about these animals and so that in fiction it would give free rein to the Imagination for the creation of films and series.
Now we have known a new discovery of a key piece in the history of the tyrannosaurus. Has been baptized as Khankhuulu Mongoliensis and can be the key piece to understand How there was an evolution from smaller predators to giants such as T-Rex.
A new advance that comes from the hand of Jared Voris and Dr. Darla Zelenitsky, from the University of Calgarand, that these interesting new data have published in Nature magazine.
The Khankhuulu, the 'Prince of Dragons' that revolutionizes science
This dinosaur is the one that closes the gap between the fast hunters and those that followed them, the bone destroyers. In fact, Khankhuuluu means “Prince of Dragons” in Mongol, an important fact since it is considered the ancestor closest to the tyrannosaurus, although it only reached The 750 kilos, what a current horse.
“This new Species allows us to observe the stage of promotion of the evolution of the tyrannosaurus, just when they are in transition of small predators to their superdedor form”, Explained Jared Voris. This dinosaur took the opportunity that gave him the extinction of other great carnivores and developed new features that would take him to the domain of his time since it was fast, agile and born persecutor.

The Khankhuulu was poorly identified
A fact to take into account about this dinosaur is that their bones were not extracted until recently from the ground. They were collected in 1970 by the paleontologist Altngengrel Perle in the Bayanshiree Formationin southeastern Mongolia, but at that time those bones were identified as A dinosaur called Alecrosaurus, more common in the nearby China. That assumption remained for decades.
However, when 2023 Voris traveled to Mongolia to study fossils in detail, found great differences. Some data that confirmed that fossils belonged to a new species. What had previously been identified now was recognized as a fundamental ancestor of the tyrannosaurus.
