Dinosaur footprints found in China

Chinese scientists today said seven footprints of Hadrosaurs have been found in south China, a discovery expected to help with the research on the evolution and migration of the duck-billed dinosaurs.
The footprints were found when Xing Lida, a PhD student with China University of Geosciences, was conducting a field study in the city of Nanxiong in Guangdong Province.
The footprints are a three-toed shape with claw marks. Each footprint is symmetrical with its length slightly longer than the width, according to Xing.
The diameters of the footprints range from 10 to 60 cm and the depths measure from 2 to 8 cm, Xing said.

The largest Hadrosaur, which left the footprints, was likely to be 8 to 10 metres in length while the smaller one was only 1.5 to 2 metres long, state-run Xinhua news agency quoted Xing as saying.
Hadrosaurs are known as duck-billed dinosaurs due to the similarity of their heads to that of modern ducks. They lived in the late Cretaceous period, about 70 million to 80 million years ago.
Their footprints were mainly found in North America and Mongolia.
The latest finding is expected to help with the research on the evolution and migration of Hadrosaurs.
