This video says about itself:
Thousands of dinosaur footprints have been discovered in the Swiss Jura region, making it one of the world’s biggest track sites. The discoveries — and the great interest in the area – have prompted the authorities to consider turning the site into a tourist and archaeological attraction.
The cyclists, just before the finish, passed a big dinosaur statue in a roundabout. The Tour de France TV helicopter also showed a dinosaur image, carved into the earth. This is because of the dinosaur discoveries of Porrentruy town.
