The fossils of the Jura were extensively studied at the end of the 18th century. The fossil-bearing limestone formations, which Alexander von Humboldt called the ‘Jura Limestone’, are the basis of the name ‘Jurassic Period’.
The Jura is also considered one of the most important sites for dinosaur footprints in the world. In one area near the village of Courtedoux, over 1’500 footprints were discovered. Many more are expected there.
