The Urweltmuseum Hauff is the largest privately run natural history museum in Germany, covering an exhibition area of around 1,000 square metres. Here, the visitor can see ichthysaurs, plesiosaurs, marine crocodiles, pterosaurs, fish, sea lilies, ammonites and belemnites – the best fossils to have been found in the shale quarries around Holzmaden in the past 100 years.
The fossils typically found in each stratum can be seen in the main museum hall. Like a gigantic history book of prehistoric times, the various strata of Posidonia shale have been reconstructed as they occur in the field. Whether it be the geology of the Swabian Jura, an interactive geological clock or the numerous life-sized dinosaur models and dioramas – illustrated charts, videos and animations provide vivid impressions of life in primeval times. Eight life-sized dinosaurs from the Mesozoic period can be found in the grounds outside the museum, on the banks of a lake amidst primeval scouring rush, ginkgo and sequoia trees. Fossils from Holzmaden are to be seen in exhibitions and museums throughout the world.
