Life
Von Quenstedt was born at Eisleben in Saxony, and educated at the Humboldt University of Berlin. Eisleben is a town in Saxony-Anhalt, Germany. It is famous as the hometown of Martin Luther, hence its official name is Lutherstadt Eisleben }The Province of Saxony (Provinz Sachsen was a province of the Kingdom of Prussia and later the Free State of Prussia from 1816 until 1945 For other universities in Berlin see List of Universities in Berlin. After a period as assistant in the mineralogical museum, he was appointed associate professor (1837) and then professor (1841) of mineralogy and geognosy at the University of Tübingen, a post which he occupied until his death. Mineralogy is an Earth Science focused around the Chemistry, Crystal structure, and physical (including optical) properties of Minerals Abraham Gottlob Werner ( September 25, 1749 &ndash June 30, 1817) was a German Geologist who set out a now obsolete theory Eberhard Karls University of Tübingen ( German: Eberhard Karls Universität Tübingen, sometimes called the "Eberhardina Carolina" is a public university The museum at Tübingen owed its establishment to him.
Work
His earlier work related chiefly to crystallography and mineralogy, on which subjects he published text-books that were widely used. Crystallography is the experimental science of determining the arrangement of Atoms in Solids In older usage it is the scientific study of Crystals The Mineralogy is an Earth Science focused around the Chemistry, Crystal structure, and physical (including optical) properties of Minerals However, he also became distinguished for his researches on palaeontology, and especially for those on the fossils of the Jurassic system. FOSSIL is a standard protocol for allowing serial communication for Telecommunications programs under the DOS Operating system. The Jurassic is a geologic period and system that extends from about Ma (million years ago to Ma that is from the end of the Triassic to the beginning
In 1845, he devised a trinomial system of nomenclature for Jurassic ammonites, which has caused some difficulty for later taxonomists[1]. He investigated series of ammonite fossils which appeared to represent the coiled and uncoiled forms of similar shells, and considered that they arose as 'pathological' forms. He also wrote several articles on pterodactyls. For other meanings see Pterodactyl (disambiguation. Pterosaurs (ˈtɛrəsɔr from the Greek πτερόσαυρος pterosauros
Two genera were named in his honour: the bivalve mollusc genus Quenstedtia Morris & Lycett 1854 and the (homonymous) coelenterate genus Quenstedtia Rominger 1876.
The mineral quenstedtite was named in his honour by G. Quenstedtite is an uncommon Iron Sulfate mineral with formula Fe2(SO43·10H20 Linck in 1888. Year 1888 ( MDCCCLXXXVIII) was a Leap year starting on Sunday (click on link for calendar of the Gregorian calendar (or a
