17 Abrosaurus Facts You’ll Never Forget

Discover amazing Abrosaurus facts!

The Abrosaurus was discovered in 1984 in Dashanpu quarry in the Sichuan province of China by Chinese paleontologist, Ouyang Hui. In 1986, in a thesis based on his findings, Ouyang first named it A. gigantorhinus or Abrosaurus gigantorhinus. The classification has undergone changes since then as the remains of this dinosaur were found in an extremely fragmented condition and to date, scientists are unsure whether the genus is separate or not. The Abrosaurus, like most sauropods, was a herbivore and from the remains found, it was rather a small sauropod about 30 ft (9.14 m) in length. The Abrosaurus was called 'delicate lizard' by its generic name which refers to its Greek name meaning delicate lizard because of its head, which had large openings which were separated by bony struts. The head had a crest mark also. Only one named species is called A. dongpoi, and is named after a famous poet of the 11th-century in China named Su Shi, or also called Su Dongpo.
