Scientists in China say they have discovered the world's largest dinosaur fossil site in the eastern province of Shandong, state media reported on Tuesday. They had recovered some 7,600 fossils from a 300 metre (980 ft) long pit near Zhucheng city over the past seven months, Xinhua news agency said. The finds included remains of a 20-meter hadrosaurus, which could be a record size for the duck-billed dinosaur, Xinhua said. Zhucheng, known locally as China's “Dinosaur City”, has produced dinosaur fossils in some 30 sites. China makes regular finds of rare fossils, which are sometimes smuggled out of the country to be sold for large sums. In January, Australia handed back hundreds of kilograms of Chinese dinosaur fossils to Beijing, including eggs dating back hundreds of millions of years, recovered from warehouses and cargo containers in sting operations.
