Khankhuuluu

吃：肉暴龍類白堊紀晚期

Khankhuuluu was a meat-eating dinosaur that lived in what is now Mongolia, about 100 to 84 million years ago. It was a cousin of the famous Tyrannosaurus rex, but it was smaller and more lightly built. Scientists think it helps show how big tyrannosaurs evolved from smaller ancestors.1 5

趣味知識

Khankhuuluu is known from fossils found in rocks that are between 100.5 and 83.6 million years old, from the Cenomanian to Santonian ages.5

Scientists think Khankhuuluu was a close relative of the group that includes Tyrannosaurus rex, but it lived earlier and was not as big.1

Khankhuuluu had a shallow skull and a gracile, or slender, build, similar to some young tyrannosaurs. This suggests it kept some baby-like features into adulthood.1

The discovery of Khankhuuluu helped scientists figure out that tyrannosaurs moved from Asia to North America and then later came back to Asia.1

Khankhuuluu is the only species in its genus, and its full scientific name is Khankhuuluu mongoliensis.5
