The holotype skull of Huayangosaurus taibaii, a stegosaurian dinosaur from the Middle Jurassic of Sichuan, China. It contains a complete skull, three neck vertebrae, three back vertebrae, four sacral vertebrae, twenty tail vertebrae, two metatarsals, three phalanges, three plates, a spike and three further osteoderms. I was lucky to photograph the skull minutes before it was retreived by three IVPP staff for research.
