Credit: XINHUA/ZHU ZHENG More than 7,600 fossilized dinosaur bones have been unearthed since March 2008 at what Chinese palaeontologists now claim is the largest dinosaur graveyard in the
world. Most of the bones date back to the Late Cretaceous period more than 100 million years ago, raising speculation that the finds could offer clues about why the creatures died out. The
discoveries, made by researchers from the Chinese Academy of Sciences, include bones from what might be the largest duck-billed dinosaur discovered to date. The site consists of 15 separate
areas in Zhucheng, Shandong province, which has yielded more than 50 tonnes of dinosaur bones since the 1960s. RIGHTS AND PERMISSIONS Reprints and permissions ABOUT THIS ARTICLE CITE THIS
