Solnhofener Plattenkalk: A Heritage Stone Of International Significance From Germany

In Bavaria (Germany), between Solnhofen and Kelheim, numerous quarries allow utilization of a thinly plated Upper Jurassic limestone known in German as the Solnhofener Plattenkalk and in English as Solnhofen Limestone. Here limestone slabs have been quarried for centuries and it is not necessary to cut the limestone with a saw as it can be split conveniently into thin and even slabs or sheets which are used for floor tiles and wall cladding. Thick slabs of especially fine quality have been used for lithography. This later utilization began in the late eighteenth century with lithographic Solnhofen Limestone soon being marketed worldwide. The industry continues on a smaller scale today. Slabs are quarried by hand so as not to break them, accounting for their high price. Because of this 'gentle' quarrying method, fossils have also been found. Although rare, over time many Solnhofen fossil specimens have found their way into natural history museums throughout the world. Most noteworthy is the early bird Archaeopteryx. Given its utilitarian usage worldwide as a lithographic stone, and its sale for centuries as floor tiles, coupled with its being a source of unique fossils, Solnhofener Plattenkalk is recommended here as a Global Heritage Stone Resource.
