MAHA Doc reveals RFK Jr BOMBSHELL
e tracks were discovered by the palaeontologist Christian Meyer in February 1988, having previously been overlooked by geologists who studied the quarry. They were the first discovered dinosaur tracks from the Late Jurassic of Switzerland. The scientific study was complicated by the steep inclination of the surface and the danger of rock fall. To allow every individual track to be reached by climbing, the entire surface was equipped with bolts. In order to produce a sitemap, the track outlines were traced with black paint and photographed perpendicular to the surface from a helicopter. Artificial casts of selected tracks were made in 1988 and 1990, and stored in the Museum of Nature in Solothurn. Meyer published a preliminary report in 1990, which noted more than 200 individual tracks, and an additional account in 1993, in which more than 380 tracks were recognised. In 2003, Meyer and Basil Thüring reported that 450 tracks are visible, with new tracks being exposed due to continued quarrying. The site has been protected as a geoheritage site (geotope), and was the first designated geotope of Switzerland. An observation platform with interpretive signs was installed to make the site accessible to visitors.

The sauropod was walking from right to left. The tracks were preserved in wackestones that formed in the intertidal zone of a carbonate platform. As the sediments are marine, the tracks provided definitive evidence that the area was above water level at the time the tracks were formed. In his 1990 description, Meyer concluded that much of the western part of what later became the Swiss Jura mountains have been emergent, as otherw
