Lommiswil tracksite
Lommiswil, Switzerland
The Lommiswil tracksite preserves fossil tracks of sauropod dinosaurs from the Late Jurassic epoch. The tracksite is located in the Jura Mountains in Switzerland, north of the village of Lommiswil and near the city of Solothurn, in limestones of the Reuchenette Formation. The site consists of around 450 individual tracks on a steeply inclined (70°) surface measuring 7,000 m2 (75, 000 sq ft) in area. Discovered in 1988 in an active quarry, it was the first Jurassic dinosaur tracksite to be discovered in Switzerland. The tracks provided evidence that the area, which was thought to have been a shallow sea, was above sea level. The site was scientifically documented by rock climbing and the use of a helicopter. The tracks are large, with hind foot impressions up to 1 m (3 ft 3 in) in length. At least 10 trackways can be seen, one of which showing a pronounced right turn. The site is protected as a geoheritage site (geotope) and accessible to the public.
