Friedrich August Quenstedt
Friedrich August von Quenstedt (July 10, 1809 – December 21, 1889), was a German geologist and palaeontologist. Life Von Quenstedt was born at Eisleben in Saxony, and educated at the Humboldt University of 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 Eberhard Karls Universität Tübingen. Work His earlier work related chiefly to crystallography and mineralogy, on which subjects he published text-books that were widely used. However, he also became distinguished for his researches on palaeontology, and especially for those on the fossils of the Jurassic system. In 1845, he devised a trinomial system of nomenclature for Jurassic ammonites, which has caused some difficulty for later taxonomists.J.H. Callomon, D. T. Donovan, & M. K. Howarth "F. A.

Pterosaur
Pterosaurs (; from Greek ''pteron'' and ''sauros'', meaning "wing lizard") is an extinct clade of flying reptiles in the order, Pterosauria. They existed during most of the Mesozoic: from the Late Triassic to the end of the Cretaceous (228 to 66 million years ago). Pterosaurs are the earliest vertebrates known to have evolved powered flight. Their wings were formed by a membrane of skin, muscle, and other tissues stretching from the ankles to a dramatically lengthened fourth finger. There were two major types of pterosaurs. Basal pterosaurs (also called 'non-pterodactyloid pterosaurs' or 'rhamphorhynchoids') were smaller animals with fully toothed jaws and, typically, long tails. Their wide wing membranes probably included and connected the hind legs. On the ground, they would have had an awkward sprawling posture, but the anatomy of their joints and strong claws would have made them effective climbers, and some may have even lived in trees. Basal pterosaurs were insectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William Thomas Blanford
William Thomas Blanford (7 October 183223 June 1905) was an English geologist and naturalist. He is best remembered as the editor of a major series on ''The Fauna of British India, Including Ceylon and Burma''. Biography Blanford was born in London to William Blanford and Elizabeth Simpson. His father owned a factory next to their house on Bouverie street, Whitefriars. He was educated in private schools in Brighton (until 1846) and Paris (1848). He joined his family business in carving and gilding and studied at the School of Design in Somerset House. Suffering from ill health, he spent two years in a business house at Civitavecchia owned by a friend of his father. His initial aim was to enter a mercantile career. On returning to England in 1851 he was induced to enter the newly established Royal School of Mines (now part of Imperial College London), which his younger brother Henry F. Blanford (1834–1893), afterwards head of the Indian Meteorological Department, had alrea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maria Von Linden
Maria von Linden (18 July 1869 – 25 August 1936) was a German bacteriologist and zoologist. She became one of the first women in Germany to be given the academic title of “professor”. She patented a type of bandage and won a prize for her research on butterfly wings. She was driven from office due to the rise of the Nazi Party in Germany. Early life Linden was born in 1869 to a German aristocratic family who lived at near Heidenheim, Kingdom of Württemberg. Her parents, Edward and Eugenie von Linden, arranged for her to attend school in Karlsruhe for four years. While at school, Linden developed an interest in maths and physics. She wrote her first paper on mineral deposits in the River Hürbe read at Karlsruhe's geological society in 1890. This paper was noticed by geologist Professor von Quenstedt from the University of Tübingen. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Proganochelys Quenstedti
''Proganochelys'' is an extinct, primitive stem-turtle that has been hypothesized to be the sister taxon to all other turtles creating a monophyletic group, the ''Casichelydia''. ''Proganochelys'' was named by Georg Baur in 1887 as the oldest turtle in existence at the time. The name ''Proganochelys'' comes from the Greek word ''ganos'' meaning 'brightness', combined with prefix ''pro'', 'before', and Greek base ''chelys'' meaning 'turtle'. ''Proganochelys'' is believed to have been around 1 meter in size and herbivorous in nature. ''Proganochelys'' was known as the most primitive stem-turtle for over a century, until the novel discovery of ''Odontochelys'' in 2008. ''Odontochelys'' and ''Proganochelys'' share unique primitive features that are not found in ''Casichelydia'', such as teeth on the pterygoid and vomer and a plate-like coracoid. ''Proganochelys'' is the oldest stem-turtle species with a complete shell discovered to date, known from fossils found in Germany, Switzerla ...

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geologist
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists. Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate ch ...
