Etymology Reptile gracieux

Abrosaurus is a genus of macronarian sauropod dinosaur from the Middle Jurassic Period of what is now Asia. It is one of many dinosaurs found at the Dashanpu Quarry in the Sichuan Province of China. Like most sauropods, Abrosaurus was a quadrupedal herbivore. It was rather small for a sauropod, measuring no more than 9.1 metres (30 ft) long. Its head was boxy and topped with a tall, bony arch containing the nostrils. The generic name refers to the nature of the skull, with large openings separated by thin, bony struts. The only named species is A. dongpoi, named after eleventh-century Chinese poet Su Shi, also known as Su Dongpo, who was born in Sichuan.
