Schlaifhausen is a location in Germany known for its rich deposits of Jurassic fossils, particularly from the Lower Jurassic.

The area around Schlaifhausen is part of a larger Jurassic marine deposit in Germany, particularly in the Swabian Jura region, which is renowned for its high-quality fossil specimens, including ammonites, marine reptiles, and other ancient marine organisms.

The ammonites found in Schlaifhausen are often remarkably well-preserved due to the fine-grained sedimentary rock of the region, which helps to protect and fossilize marine life over millions of years.
