Thousands of dinosaur footprints dating back 210 million years have been found in a national park in northern Italy, BBC reported. 

The footprints - some of which are up to 40cm (15in) in diameter - are aligned in parallel rows, and many show clear traces of toes and claws. 

It is thought the dinosaurs were prosauropods - herbivores with long necks, small heads and sharp claws, according to BBC.
