Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Franz Nopcsa Von Felső-Szilvás
Baron Franz Nopcsa von Felső-Szilvás (also Baron Nopcsa von Felső-Szilvás, Baron Nopcsa, Ferenc Nopcsa, báró felsőszilvási Nopcsa Ferenc, Baron Franz Nopcsa, and Franz Baron Nopcsa; May 3, 1877 – April 25, 1933) was a Hungarian Aristocracy (class), aristocrat, adventurer, scholar, geologist, Paleontology, paleontologist and albanologist. He is widely regarded as one of the founders of paleobiology, and first described the theory of insular dwarfism. He was also a specialist on Albanology, Albanian studies and completed the first geological map of northern Albania. The essay, first published on Elsie's website, is the basis for the "Introduction" to Nopcsa's memoirs titled ''Traveler, Scholar, Political Adventurer'' (2014) edited by Robert Elsie. Life Nopcsa was born in 1877 in Déva, Transylvania, Kingdom of Hungary (today Deva, Romania), to the Hungarian nobility, Hungarian Nopcsa Aristocracy (class), aristocratic family of Romanians in Hungary, Romanian origin.

Crown Group
In phylogenetics, the crown group or crown assemblage is a collection of species composed of the living representatives of the collection, the most recent common ancestor of the collection, and all descendants of the most recent common ancestor. It is thus a way of defining a clade, a group consisting of a species and all its extant or extinct descendants. For example, Neornithes (birds) can be defined as a crown group, which includes the most recent common ancestor of all modern birds, and all of its extant or extinct descendants. The concept was developed by Willi Hennig, the formulator of phylogenetic systematics, as a way of classifying living organisms relative to their extinct relatives in his "Die Stammesgeschichte der Insekten", and the "crown" and "stem" group terminology was coined by R. P. S. Jefferies in 1979. Though formulated in the 1970s, the term was not commonly used until its reintroduction in 2000 by Graham Budd and Sören Jensen. Contents of the crown gr ...

Testudinata
Testudinata is the group of all tetrapods with a true turtle shell. It includes both modern turtles (Testudines) and many of their extinct, shelled relatives (stem-turtles). Though it was first coined as the group containing turtles by Jacob Theodor Klein in 1760, it was first defined in the modern sense by Joyce and colleagues in 2004. Testudinata does not include the primitive stem-turtle ''Odontochelys'', which only had the bottom half of a shell. A recent phylogenetic tree of Testudinata included Angolachelonia and Testudines Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked t ... as sister-taxa and subgroups of Testudinata.

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Eberhard Fraas
Eberhard Fraas (26 June 1862 – 6 March 1915) was a German scientist, geologist and paleontologist. He worked as a curator at the Stuttgarter Naturaliensammlung and discovered the dinosaurs of the Tendaguru formation in then German East Africa (now Tanzania). The dinosaur ''Efraasia'' is named after him. Life Eberhard Fraas was born in Stuttgart, the son of Oscar Fraas (1824–1897), a curator and professor at the geological and paleontological department of the Württemberg Royal Natural Cabinet. After attending the Gymnasium, he studied at Leipzig University with Hermann Credner and Ferdinand Zirkel, and later in Munich under Karl Alfred von Zittel, August Rothpletz (1853−1918) and Paul Groth. Here, he received his Ph.D in 1886 with a dissertation about Jurassic starfish. His geological work enabled him to publish the first coherent account about the history of the Alps. In July 1888, he received his Habilitation (second Ph.D.) from Munich University, and in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
