這項發現更新了霸王龍的家族譜，並改變了我們對它們演化的理解。
When you think about the T.rex, you probably picture a big predator with small arms and big teeth.
The early ancestors of the T.rex look less fearsome, and a new species of dinosaur has been discovered which is believed to be its closest relative.
The species is called Khankhuuluu mongoliensis, named the Dragon Prince of Mongolia.
This discovery aids in understanding the evolution of the T.rex from its small early ancestors.
At the University of Calgary, researchers studied two partial skeletons found in Mongolia in the 1970s that were stored in a museum.
The fossils are 86 million years old and provide new insights into how tyrannosaurs evolved.
A PhD student, Jared Voris, noticed similarities between the newly discovered species and the T.rex, such as a strong jaw for a powerful bite.
Having evolved such powerful jaws allowed the T.rex to hunt larger prey and even bite through bones.
Tyrannosauroids are a superfamily of bipedal, carnivorous dinosaurs.
The first tyrannosauroids were small and agile, coexisting with larger predators.
The new species, Khankhuuluu, is considered a transitional fossil between early ancestors and the powerful tyrannosaurs.
It weighed around 750kg, in contrast to the much larger adult T.rex weighing up to eight times more.
The discovery has updated the tyrannosaur family tree and altered our understanding of their evolution.
