'''''Heishansaurus''''', meaning "Heishan lizard" after the area in [[China]] where it was discovered, is the name given to a dubious [[genus]] of herbivorous [[ornithischian]] [[dinosaur]], probably belonging to the [[Ankylosauridae]].

	In 1930, Swedish palaeontologist [[Anders Birger Bohlin]] discovered dinosaur fossils, in the context of the Swedish-Chinese expeditions headed by [[Sven Hedin]], near [[Jiayuguan City\|Jiayuguan]] ("Chia-Yu-Kuan"), in the west of [[Gansu]] Province.
