趣味知識

Asiatyrannus had a deep snout, unlike its long-snouted relative Qianzhousaurus that lived in the same time and place.1 2

The only known fossil of Asiatyrannus is a sub-adult that was at least 13 years old when it died.2

Its skull was 47.5 cm long, and its femur (thigh bone) was 44 cm long.2

Asiatyrannus is named after Asia and the Latin word for 'king' or 'tyrant'.1

The species name xui honors Dr. Xing Xu, a famous Chinese dinosaur scientist.1

Asiatyrannus and Qianzhousaurus likely ate different prey because of their different skull shapes and sizes.1 2
