Although joints can occur singly, they most frequently appear as joint sets and systems. A joint set is a family of parallel, evenly spaced joints that can be identified through mapping and analysis of their orientations, spacing, and physical properties. A joint system consists of two or more intersecting joint sets. [1] [2] [3]
The surface geology of Germany has evolved to its current configuration due to regional differences in the action and appearance of external and internal forces during the last c. 20 million years. Germany can be divided into three physiographic regions: the Central European Depression, the Central European Blocks and the Alps.
In respect of the locality being a 'first-class paleontological site displaying high-quality reference material for scientists worldwide, including all known specimens of Archaeopteryx ', the International Union of Geological Sciences (IUGS) included the 'Jurassic Solnhofen-Eichstätt Archaeopteryx Serial Site' in its assemblage of 100 'geological heritage sites' around the world in a listing ...

The Solnhofen Limestone or Solnhofen Plattenkalk is a collective term for multiple Late Jurassic lithographic limestones in southeastern Germany, which is famous for its well preserved fossil flora and fauna dating to the late Jurassic (Kimmeridgian-Tithonian). The paleoenvironment is also often referred to as the Solnhofen Archipelago.
Historical geology or palaeogeology is a discipline that uses the principles and methods of geology to reconstruct the geological history of Earth. [1] Historical geology examines the vastness of geologic time, measured in billions of years, and investigates changes in the Earth , gradual and sudden, over this deep time .

The Messel Formation is a geologic formation in Hesse, central Germany, dating back to the Eocene epoch (about 47 Ma [1]). Its geographic range is restricted to the Messel pit. There it unconformably overlies crystalline Variscan basement and its Permian cover as well as Eocene volcanic breccias derived from the basement rocks.
