The exhibition shows 170 million year-old finds of echinoderms from the Swiss Jura. The highlight of the exhibition is a rock slide showing a sea urchin, starfish, brittle stars, crinoids and sea cucumbers. This site in the Jura region was the scene of a major storm 170 million years ago. The fallen animals were covered in fine-grained mud. This great disaster became a stroke of luck for the paleontologists.
