Turpan (China) : Chinese and German experts on Thursday said they had unearthed a large group of fossilized dinosaur tracks, the largest cluster ever found in China, in the northwestern Xinjiang Uygur Autonomous Region.
China’s Xinhua news agency reported that the find, in a small county east of here, consists of more than 150 tridactyl footprint fossils distributed randomly on the slope of a 100-metre sandstone incline.
The largest is 33.6 centimetres long, while the smallest is a mere 11.4 cm. Experts confirmed that the footprints were made by two kinds of large carnivorous dinosaurs, known as theropods.
They lived during the Middle Jurassic Period, about 165 million years ago, said professor Sun Ge, a paleontologist at Jilin University in northeast China.
Judging by the footprints, the dinosaurs would have been three to five metres tall, eight to 10 metres long and weighed two to three tonnes, scientists said.
Dong Zhiming, a professor known as China’s dinosaur king, said:”The site not only adds the first record of dinosaur footprint fossils in Xinjiang, but it is the largest Middle Jurassic dinosaur footprint fossil finding ever unearthed in China.”
Little fossilised evidence of Middle Jurassic dinosaurs has been found anywhere in the world. Fossils were only excavated in the southwestern provinces of Sichuan and Yunnan, and until now, no fossilised footprints have been discovered in the country.
The tracks were accidentally discovered by experts of the Sino-German Joint Group on Mesozoic stratigraphy and paleontology last September, but they were unable to proceed with their excavation until the severe winter had passed.
Experts are now wondering how to protect this find. Local authorities in Xinjiang have built roofs and protective siding to prevent weathering and erosion.
The government is also preparing to set up facilities that will give dinosaur enthusiasts from around the world a chance to get a good look at the footprints.
