The White Quarry is a former quarry south of Pfaffenhofen in Württemberg on the crest of the Stromberg.
The white quarry was used to quarry Stubensandstein as a building material. It was only in operation from 1902 to 1914, but became famous for its fossil finds. Fossils have been found both in the sandstone itself and in the clay layers in between.
Above all, fossils of reptiles, especially dinosaurs and primeval crocodiles, as well as amphibians were found. No other quarry in Keuper has such a wealth of finds. They go back to about 220 million years before our time. The first find came into the possession of the Royal Stuttgart Natural History Cabinet in 1906: the lessee of the quarry, Albert Burrer, presented Eberhard Fraas with a piece of the trunk of an aetosaur. Another spectacular discovery was the skeletal remains of a Sellosaurus (today's scientific name Plateosaurus gracilis), one of the oldest European land dinosaurs.
A viewing platform was set up on the edge of the mountain in front of the quarry, from which the view extends over the entire Zabergäu and large parts of the Heilbronn Neckarland to the heights of the Odenwald.
The White Quarry has been an extensive natural monument since 1986. It is also protected as a geotope under the name Abandoned White Quarry SW from Rodbachhof.
