The Solnhofen limestone is a famous Lagerstätte in Germany that offers amazing preservation of Upper Jurassic fossils. The area represented an archipelago at the edge of a sea. Due to high salt content, the lowest levels in the water column could not support much life and were largely devoid of oxygen. The lack of oxygen and scavengers on the bottom of the sea led to spectacular fossil preservation.
