Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal '' Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Middle Ordovician
The Ordovician ( ) is a geologic period and system, the second of six periods of the Paleozoic Era. The Ordovician spans 41.6 million years from the end of the Cambrian Period million years ago (Mya) to the start of the Silurian Period Mya. The Ordovician, named after the Welsh tribe of the Ordovices, was defined by Charles Lapworth in 1879 to resolve a dispute between followers of Adam Sedgwick and Roderick Murchison, who were placing the same rock beds in North Wales in the Cambrian and Silurian systems, respectively. Lapworth recognized that the fossil fauna in the disputed strata were different from those of either the Cambrian or the Silurian systems, and placed them in a system of their own. The Ordovician received international approval in 1960 (forty years after Lapworth's death), when it was adopted as an official period of the Paleozoic Era by the International Geological Congress. Life continued to flourish during the Ordovician as it did in the earlier Cambrian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newton Horace Winchell
Newton Horace Winchell (17 December 1839 – 2 May 1914) was an American geologist chiefly notable for his six-volume work ''The Geology of Minnesota: Final Report of the Geological and Natural History Survey of Minnesota'', which was prepared by Winchell and his assistants. A bibliography of his publications by Warren Upham in the ''Bulletin of the Geological Society of America'' (volume 26, pp. 27–46) contains almost 300 titles. Biography Born in New York State, the younger brother of geologist Alexander Winchell, Newton Horace Winchell attended public school in Connecticut and then taught school in Connecticut and Michigan. While teaching in Michigan he graduated from the University of Michigan and received a Master of Arts degree in 1867. He then did geological studies in Michigan, Ohio, and New Mexico. Winchell settled in Minnesota in 1872 when he was appointed to direct the Geological and Natural History Survey of Minnesota. At the same time, he taught courses in ...

Jaroslav Perner
Jaroslav Perner (March 28, 1869 in Týnec nad Labem – June 9, 1947 in Prague) was a Czech paleontologist. In 1927 Perner became professor of paleontology at the Charles University in Prague. He continued in work started by Joachim Barrande (the ''Systéme silurien du center de la Bohéme''). He was also custodian of the Czech National Museum The National Museum (NM) (Czech: ''Národní muzeum'') is a Czech museum institution intended to systematically establish, prepare, and publicly exhibit natural scientific and historical collections.

Joachim Barrande
Joachim Barrande (11 August 1799 – 5 October 1883) was a French geologist and palaeontologist. Career Barrande was born at Saugues, Haute Loire, and educated in the École Polytechnique and École Nationale des Ponts et Chaussées at Paris. Although he had received the training of an engineer, his first appointment was that of tutor to the duc de Bordeaux (afterwards known as the comte de Chambord), grandson of Charles X, and when the king abdicated in 1830, Barrande accompanied the royal exiles to England and Scotland, and afterwards to Prague. Settling in that city in 1831, he became occupied in engineering works, and his attention was then attracted to the fossils from the Lower Palaeozoic rocks of Bohemia. The publication in 1839 of ''Murchison's Silurian System'' incited Barrande to carry on systematic researches on the equivalent strata in Bohemia. For ten years (1840–1850) he made a detailed study of these rocks, engaging workmen specially to collect fossils, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
