Experts say they have discovered the world's largest dinosaur fossil site in the eastern province of Shandong, Reuters reported. They had recovered some 7,600 fossils from a 300 metre (980 ft) long pit near Zhucheng city over the past seven months. The finds included remains of a 20-metre hadrosaurus, which could be a record size for the duck-billed dinosaur. Scientists had put down tools for the winter, but said further excavations could yield more fossils.
