The Plattensandstein is a Middle Triassic (Anisian) geologic formation in southern Germany and northern Switzerland. Fossil theropod tracks have been reported from the formation.

Plattensandstein is used in Germany as a natural building stone. It derives its name from the fact that it is usually fissile into slabs with a thickness of several centimeters.

The formation has provided fossils of:

• Basileosaurus freyi
• Sclerosaurus armatus

• List of dinosaur-bearing rock formations
  • List of stratigraphic units with theropod tracks
• Flagstone, another scissile sandstone, which is used as a roofing material
