Bellusaurus ("beautiful lizard") was a small short-necked sauropod dinosaur from the Middle Jurassic which measured about 4.8 metres (16 ft) long. Its fossils were found in Shishugou Formation rocks in the northeastern Junggar Basin in China.
Discovery and species
The type (and only known) species is Bellusaurus sui, formally described by Dong Zhiming in 1990. Seventeen individuals were found in a single quarry, suggesting that a herd had been killed in a flash flood. Some features suggest they may have all been juveniles.
