Reinhold Seemann

from Wikipedia, the free encyclopedia

Reinhold Seemann (born May 5, 1888 in Stuttgart -Cannstatt; † December 17, 1975 in Marburg -Wehrda) was a German geologist and paleontologist .

Life

Seemann studied natural sciences and especially geology and mineralogy in Tübingen, Freiburg, Berlin and Stuttgart. During the First World War he was a frontline officer and was wounded twice, losing one eye and then wearing an eye patch. On leave from the front, he received his doctorate in Tübingen in 1917 with a thesis on the petrology of Triassic sediments near Freudenstadt . After the war he worked for the German-Luxemburgish Mining and Huts-AG in Hersbruck (there are iron ore-containing marine sediments from the Cretaceous period) and from 1925 he was conservator for geology at the Natural History Museum in Stuttgart , where he became chief conservator in 1938. From 1946 to 1949 he was acting head of the collections there. From 1940 to 1947 he also taught geology as a deputy lecturer at the Hohenheim Agricultural University . In 1950 he retired.

He also played a role in the nature of the structure of the Nördlinger Ries , which he saw as a result of long-lasting tectonic processes. He was the main proponent of this outsider theory, which stood in opposition to both an impact crater theory and volcanic theories. According to it, in the course of the unfolding of the Alps, a crystalline clod would have been pushed to the north in a wedge shape, shattered at the top as a boiler break, accompanied by slight volcanism. According to his doctoral student Helmut Hölder , this reflected his conservative nature.

In 1932 he led the third and most extensive excavation for dinosaurs ( plateosaurs ) in Keuper -Mergel von Trossingen . Around 30 helpers from the voluntary labor service formed during the economic crisis at the time were involved; they were supported by the city, employment offices and the Hohner company . The excavation area at the upper mill of the Trosselbach valley was 80,000 square meters and 750,000 cubic meters of earth were moved. Four complete plateosaur skeletons and 17 larger skeletal remains were found, but there was also one death due to rain-related landslides in the marl. The excavation, which was preceded by that of Eberhard Fraas (1911/12) and Friedrich von Huene (1921/22), was the largest dinosaur excavation ever to take place in Germany. Parts are exhibited in the Auberlehaus Museum .
