The white limestone layers of the Upper Cretaceous period (Turonian-Coniac) are exposed in the quarry. After more than 90 million years, traces of creatures that populated the Cretaceous sea at the end of the Mesozoic era can still be found here. The most common remains are those of brachiopods (arthropods), ammonites (cephalopods), sea urchins, mussels and sponges - but perhaps also teeth from sharks or the mosasaur.

The quarry, located in the north-eastern part of the Lichtenberg mountain range, is owned by the Natural Landscape Foundation and is managed by BUND Salzgitter.

The meeting point is on the rocky path in Salder, in front of the barrier to the quarry. Bring your own helmet, safety goggles and hammer. If required, these can also be borrowed while stocks last. Sturdy shoes are required. The tour is only possible in dry weather.

The quarry can only be entered outside the Geotope Day by prior arrangement!
