Gunnar Säve-Söderbergh
Gunnar Säve-Söderbergh (31 January 1910 – 8 June 1948) was a Swedish palaeontologist and geologist. Säve-Söderbergh was born at Falun, the son of the neurologist Gotthard Söderbergh and Inga Säve. He passed his G.C.E. at Gothenburg in 1928 and took bachelor's and licentiate's degrees at Uppsala University in 1931 and 1933, respectively. He was appointed professor of geology, historical geology in particular, at Uppsala in 1937. Career Säve-Söderbergh participated in Lauge Koch's Three-year Expedition to East Greenland in 1931-1934 and 1936. He brought back fossils of ''Ichthyostega,'' by then the earliest known tetrapod, and published an extensive preliminary report on it in 1932. He also collected fossils on Cyprus (1930), in England and Scotland (1934), and Estonia (1936). Säve-Söderbergh went on to study the biostratigraphy of the East Greenland Palaeozoic and the problem of skull bone homologies among fishes and tetrapods. He also investigated the crania ...

Historical Geology
Historical geology or palaeogeology is a discipline that uses the principles and methods of geology to reconstruct the geological history of Earth. 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. It focuses on geological processes, such as plate tectonics, that have changed the Earth's surface and subsurface over time and the use of methods including stratigraphy, structural geology, paleontology, and sedimentology to tell the sequence of these events. It also focuses on the evolution of life during different time periods in the geologic time scale. Historical development During the 17th century, Nicolas Steno was the first to observe and propose a number of basic principles of historical geology, including three key stratigraphic principles: the law of superposition, the principle of original horizontality, and the principle of lateral continuity. 18th- ...
