The list of Lagerstätten is a documentation of Lagerstätte fossils sites around the world, arranged by geologic age. These are characterized by exceptional preservation of fossil organisms, regularly including many well-preserved animals and their soft tissue remains. The extent of Lagerstätten deposits can range from a select site or stratigraphic layer to a whole formation or group. Some sites that one author calls a single Lagerstätte may be called multiple by another. This list attempts to note this in the text and provide the formation or stratigraphic unit from which a site came.
