Piesberg near Osnabrück

Germany

Steinbruch Piesberg is a sandstone quarry. The quarry itself has been active since the middle of the 19th century, but the mining activities at this location date from as early as 1461.

The area was first mined for coal. Piesberg is one of the very few outcrops in Northern Germany where you can dig Carboniferous layers. The quarry itself is famous for its plant fossils from the Carboniferous period, but you can also find remains of dragonflies, roaches, arachnids, arthropleuridae, scorpions and of course horseshoe crabs. Freshwater shells also occur, but they are rare.
