What Fossils You'll Find:
Werkforum Dotternhausen Klopfplatz contains Early Jurassic fossils preserved in Posidonia Shale from the Toarcian Stage, approximately 182 million years ago.

Ammonites are the primary fossil assemblage at the site. Belemnites are also found abundantly throughout the collecting material. Fish fossils, bivalves, and marine reptile bone fragments occur regularly and have been discovered at Werkforum Dotternhausen. The museum displays specimens including ichthyosaurs and marine crocodiles professionally prepared from quarry material.

Geologic History:
Werkforum Dotternhausen Klopfplatz exposes the Posidonia Shale, a significant Early Jurassic geological unit in Baden-Württemberg, Germany.

Millions of years ago, the area that is now Baden-Württemberg was covered by an ancient epicontinental sea where organic-rich muds accumulated on the seafloor. The Early Jurassic climate was warm temperate with temperatures averaging 18-22°C. The marine environment featured relatively deep, calm waters with low-oxygen bottom conditions. The ecosystem included abundant ammonites, belemnites, fish, and marine reptiles including ichthyosaurs and plesiosaurs.

As these ancient organisms died, organic-rich muds buried and preserved their remains. The low-oxygen conditions prevented decomposition and scavenging. Over millions of years, geological processes transformed these sediments into the oil shale that is now used for cement production at Dotternhausen, continuously revealing new fossils.

How Werkforum Dotternhausen Became a Fossil Collecting Site:
Werkforum Dotternhausen was established by Dotternhausen Cement Works, which has operated since 1939 using the Posidonia Shale for cement production.

The fossil content was recognized early, and the company established a professional fossil preparation department to study and preserve significant specimens. In 1989, the company opened the Werkforum, a modern museum showcasing spectacular fossils from the quarries including complete ichthyosaurs and marine crocodiles. A public Klopfplatz was established adjacent to the museum, allowing visitors to search for fossils in oil shale provided from the quarries. The museum employs professional preparators who work with university researchers including the University of Tübingen to study significant finds. The facility represents an excellent example of industrial operations supporting paleontological research and public education.
