Giraffatitan
''Giraffatitan'' (name meaning "titanic giraffe") is a genus of sauropod dinosaur that lived during the late Jurassic Period (geology), Period (Kimmeridgian–Tithonian stages) in what is now Lindi Region, Tanzania. It was originally named as an African species of ''Brachiosaurus'' (''B. brancai''), but this has since been moved to its own genus. ''Giraffatitan'' was for many decades known as the largest dinosaur but recent discoveries of several larger dinosaurs prove otherwise; giant titanosaurians appear to have surpassed ''Giraffatitan'' in terms of sheer mass. Also, the sauropod dinosaur ''Sauroposeidon'' is estimated to be taller and possibly heavier than ''Giraffatitan''. Most size estimates for ''Giraffatitan'' are based on the specimen HMN SII, a subadult individual, but there is evidence supporting that these animals could grow larger; specimen HMN XV2, represented by a fibula 13% larger than the corresponding material on HMN SII, might have attained in length and ...

Brachiosaurus
''Brachiosaurus'' () is a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about 154to 150million years ago. It was first described by American paleontologist Elmer S. Riggs in 1903 from fossils found in the Colorado River valley in western Colorado, United States. Riggs named the dinosaur ''Brachiosaurus altithorax''; the generic name is Greek for "arm lizard", in reference to its proportionately long arms, and the specific name means "deep chest". ''Brachiosaurus'' is estimated to have been between 18 and 22 meters (59 and 72ft) long; body mass estimates of the subadult holotype specimen range from 28.3 to 46.9 metric tons (31.2 and 51.7 short tons). It had a disproportionately long neck, small skull, and large overall size, all of which are typical for sauropods. Atypically, ''Brachiosaurus'' had longer forelimbs than hindlimbs, which resulted in a steeply inclined trunk, and a proportionally shorter tail. ''Brachiosaurus'' is the name ...

Sauroposeidon
''Sauroposeidon'' ( ; meaning "lizard earthquake god", after the Greek god Poseidon) is a genus of sauropod dinosaur known from several incomplete specimens including a bone bed and fossilized trackways that have been found in the U.S. states of Oklahoma, Wyoming, and Texas. The fossils were found in rocks dating from near the end of the Early Cretaceous (Aptian–early Albian), from about 113 to 110 million years ago, a time when sauropod diversity in North America had greatly diminished. It was the last known North American sauropod prior to an absence of the group on the continent of roughly 40 million years that ended with the appearance of ''Alamosaurus'' during the Maastrichtian. While the holotype remains were initially discovered in 1994, due to their unexpected age and unusual size they were initially misclassified as pieces of petrified wood. A more detailed analysis in 1999 revealed their true nature which resulted in a minor media frenzy, and formal publication of th ...

Natural History Museum, Berlin
The Natural History Museum (german: Museum für Naturkunde) is a natural history museum located in Berlin, Germany. It exhibits a vast range of specimens from various segments of natural history and in such domain it is one of three major museums in Germany alongside ''Naturmuseum Senckenberg'' in Frankfurt and ''Museum Koenig'' in Bonn. The museum houses more than 30 million zoological, paleontological, and mineralogical specimens, including more than ten thousand type specimens. It is famous for two exhibits: the largest mounted dinosaur in the world (a ''Giraffatitan'' skeleton), and a well-preserved specimen of the earliest known bird, '' Archaeopteryx''. The museum's mineral collections date back to the Prussian Academy of Sciences of 1700. Important historic zoological specimens include those recovered by the German deep-sea Valdiva expedition (1898–99), the German Southpolar Expedition (1901–03), and the German Sunda Expedition (1929–31).

Lindi Region
Lindi Region (''Mkoa wa Lindi'' in Swahili) is one of Tanzania's 31 administrative regions. The region covers an area of . The region is comparable in size to the combined land area of the nation state of Sri Lanka. The regional capital is the municipality of Lindi. The Lindi Region borders on Pwani Region, Morogoro Region, Ruvuma Region, and Mtwara Region. The name Lindi is an old Swahili word meaning "hiding pits", a place where Swahili people will hide to defend themselves from hostile invasions. The region is home to two UNESCO World Heritage Sites, namely; Kilwa Kisiwani and Selous Game Reserve. According to the 2012 national census, the region had a population of 864,652, which was lower than the pre-census projection of 960,236.

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among ...

Wilhelm Von Branca
Carl Wilhelm Franz von Branca Until 1895: Wilhelm Branco; 1895-1907: Wilhelm von Branco (9 September 1844 – 12 March 1928) was a German geologist and paleontologist. Biography Von Branca was born in Potsdam. After having been an officer, and then a farmer, Branca studied geology in Halle and Heidelberg, receiving his doctorate in 1876. He did postdoctoral work in Straßburg, Berlin, Munich, and in Rome with Karl Alfred von Zittel. In 1881 he received his habilitation from the Friedrich-Wilhelms-University Berlin (today's Humboldt-Universität zu Berlin), where he then worked as a lecturer. After a short stint as a lecturer in Aachen, von Branca became State Geologist at the Prussian Geological State Service in Berlin. From 1887 to 1890 he served as professor for geology and paleontology in Königsberg, until 1895 in Tübingen, then for four years (until 1899) in Hohenheim, until finally settling down in Berlin, where he was professor of geology until 1917, doubling as the ...

Sauropod
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include ''Brachiosaurus'', ''Diplodocus'', ''Apatosaurus'' and ''Brontosaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. ''Isanosaurus'' and ''Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the occurrence of the group in the Late Triassic. By the Late Jurassic (150 million yea ...

Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of dinosau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Werner Janensch
Werner Ernst Martin Janensch (11 November 1878 – 20 October 1969) was a German paleontologist and geologist. Biography Janensch was born at Herzberg (Elster). In addition to Friedrich von Huene, Janensch was probably Germany's most important dinosaur specialist from the early and middle twentieth century. His most famous and significant contributions stemmed from the expedition undertaken to the Tendaguru Beds in what is now Tanzania. As leader of an expedition (together with Edwin Hennig) set up by the Museum für Naturkunde in Berlin, where he worked as a curator, Janensch helped uncover an enormous quantity of fossils of late Jurassic period dinosaurs, including several complete ''Brachiosaurus'' skeletons, then the largest animal ever known. During his long subsequent career (he worked in Berlin from 1914 to 1961), Janensch named several new dinosaur taxa including ''Dicraeosaurus'' (1914) and ''Elaphrosaurus'' (1920). Janensch's ''Brachiosaurus'' were later determ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Duke Of Mecklenburg
This list of dukes and grand dukes of Mecklenburg dates from the origins of the German princely state of Mecklenburg's royal house in the High Middle Ages to the monarchy's abolition at the end of World War I. Strictly speaking, Mecklenburg's princely dynasty was descended linearly from the princes (or kings) of a Slavic tribe, the Obotrites, and had its original residence in a castle (Mecklenburg) in Dorf Mecklenburg (Mikelenburg) close to Wismar."Fürsten und Gutsherren..." As part of a feudal union under German law from 1160—at first under the Saxons—Mecklenburg was granted imperial immediacy in 1348 and its princely rulers styled Dukes of Mecklenburg. Despite several partitions, Mecklenburg remained an integral state until the end of the monarchy. The First Partition of Mecklenburg came in 1234, causing the principality to lose land. Thus arose the partial principalities (lordships) of Werle, Parchim-Richenberg, Rostock and Mecklenburg. In modern times it was divided int ...
