Fossil hunters in France have found some of the largest dinosaur footprints ever documented, measuring 1.5 metres in diameter. The prints were made about 150 million years ago by large, long-necked, herbivorous dinosaurs called sauropods, which were more than 25 metres long and weighed up to 40 tonnes.

Paleontologist Jean-Michel Mazin of France's National Centre of Scientific Research (CNRS) said 20 prints have been found on a 10-hectare site near Plagne in eastern France. The site in the Jura Mountains was a flat, muddy area near a shallow sea when the sauropods lived there, in the Jurassic period, which takes its name from the mountains. Mazin said there could be hundreds or even thousands more footprints still hidden. From the prints, "we can calculate their size and speed, find out about their behaviour and learn how they got around," Mazin told The Associated Press. READ MORE
