The new view fills an important space in the history of the Evolution of Tyrannosaurs, researchers say.
In the above Mongolian sediments, paleontologists have discovered a new type of dinosaur, which can radically change the evolution of the tyrannosaurs, reports IFLSCIENCE. The new predator is called Khankhuulu Mongoliensis, translated from Mongolian means “Dragon Prince.” He is the closest famous ancestor of Tyrannosaurs.
Found dates from about 86 million years ago and manufactured based on two partial outlines, stored in the museum collection since the early 1970s.
Khankhuulu weighed about 750 kg, body length of about 4 meters and reached 2 meters high on the hips. According to scientists, from this species that began the evolution line, which, after many moving waves between Asia and North America, led to the emergence of the most popular Mesozoic Predator – Tyrannosaurus Rex.
For a long time it has been believed that the smaller family representatives, especially the so -called “Tyrannosaurs Pinocchio” (official – Alioramals) – are primitive forms. However, the discovery of Khankhuulu refused this view. A new study suggests that these “mini -tyirs” are not non -failing forms, but rather highly expert, evolutionary developed species.
“Khankhuulu is a lack of a link between small species weighing about 200 kg and giants weighing over 1000 kg,” explained Darla Zelenitskaya, a co -investigator from the University of Calgary. “This discovery has made us re -consider the whole associated full of tyrannosaurs. We see that the size does not necessarily indicate the level of evolutionary development.”
The study has been published in the journal nature.
We remind you, earlier reported that in Mongolia they found a dinosaur with two giant claws.
A new dinosaur was found in Patagonia
