Paléosite de Sansan is a paleontology site located in Sansan, a small town in Occitania. It is part of the French National Museum of Natural History. It is one of the three most famous paleontology sites in the sphere of global paleontology and its findings date back to 15 million years ago. Two great discoveries come from the site: that, in 1837, of a jaw of Pliopithecus antiquus and that, in 1852, of a mastodon skeleton, the first to be reconstructed in Europe and the second in the world. It is configured as a path about 3 km long along which there are nine pedagogical stations; each of the stations deals with a different theme, such as the discovery of the site, the scientific context of the time, the flora, the work of paleontologists. Visitors are offered a real sensitive and interactive experience, thanks also to multimedia contents.
