Xiongguanlong

Igama lithetha: “Xiongguanlong means 'Xiong Guan lizard', named after the Jiayuguan Pass, a famous gateway on the Great Wall of China.”1
Yayitya: InyamaIityrannosauriiCretaceous yokuqala

Xiongguanlong was an early cousin of the mighty T. rex. It had a long, narrow snout and lived in what is now China about 120 million years ago. It was a meat-eater that could run after its prey.12

izinto ezimnandi

Iinyani ezimnandi

1

Xiongguanlong had a narrow and long muzzle, similar to the later tyrannosaur Alioramus.1

2

It is the sister taxon to Tyrannosauridae plus Appalachiosaurus, meaning it is closely related to the family that includes T. rex.1

3

Xiongguanlong shows several features that later became hallmarks of tyrannosaurids, like a sharp crest on the top of its skull and a boxy braincase.1

4

Its premaxillary teeth had a ridge on the inner side, a feature seen in later tyrannosaurids.1

5

The slender, unornamented nasals of Xiongguanlong suggest that the evolution of tyrannosaur feeding adaptations was more complex than previously thought.1

6

Xiongguanlong lived during the Aptian to Albian stages, about 121.4 to 113.2 million years ago.2

Umfanekiso owenziwe yi-AI obonisa indlela Xiongguanlong esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.
ubuzile

Eyona mibuzo ibuzwa kakhulu: Xiongguanlong

?How big was Xiongguanlong?

About 5 metres (16 feet) long and weighed around 270 kilograms (600 pounds).34

?What did Xiongguanlong eat?

It was a meat-eater that hunted small- to medium-sized animals.4

?When did Xiongguanlong live?

It lived during the Early Cretaceous, about 121 to 100 million years ago.34

?Where was Xiongguanlong found?

Its fossils were discovered in Gansu, western China.34

?Was Xiongguanlong a dinosaur?

Yes, it was a theropod dinosaur and an early cousin of T. rex.34

?Why did Xiongguanlong have a long snout?

Its long, narrow snout was similar to Alioramus and may have helped it catch smaller prey.34

Xiongguanlong was named by Daqing Li and colleagues in 2009 based on a fossil found in the Xinminpu Group of Gansu, China.1
Kusaxoxwa ngayo
Scientists are still debating how body size evolved in tyrannosauroids, and whether the trend of increasing size seen in North American tyrannosaurids extends through the whole group.1
