Acer Whitebirdense
''Acer whitebirdense'' is an extinct maple species in the family Sapindaceae described from a number of fossil leaves and samaras. The species is known from Miocene sediments exposed in Idaho, Oregon and Washington in the United States. It is one of several extinct species belonging to the living section '' Rubra''. History and classification ''Acer whitebirdense'' is known from a number of isolated leaves and fruits found in central Idaho, northeastern Oregon, and central and eastern Washington state. The holotype specimen was collected from exposures of the Latah Formation at White Bird, Idaho, and both leaves and fruits have been recovered from White Bird. Fruits are also identified from the Latah formation outcrops near Grand Coulee, Washington, the Brickyard and Spokane, Portland & Seattle Railway roadcut in Spokane, Washington. In Oregon, fruits and leaves were identified by Wolfe and Toshimasa Tanai from a site near "Baker", and isolated fruits were noted from the S ...

Bahariya Formation
The Bahariya Formation (also transcribed as Baharija Formation) is a fossiliferous geologic formation dating back to the early Cenomanian, which outcrops within the Bahariya depression in Egypt, and is known from oil exploration drilling across much of the Western Desert where it forms an important oil reservoir.Weishampel, David B; et al (2004). "Dinosaur distribution (Late Cretaceous, Africa)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 604. . Extent The Bahariya Formation forms the base of the depression, the lower part of the enclosing escarpment and all of the small hills within. The type section for the formation is found at Gebel El-Dist, a hill at the northern end of the Bahariya depression. Stratigraphy and sedimentology Four depositional sequences have been recognised in the Bahariya Formation in the Bahariya depression, separated by three sub-aerial unconformities. Th ...

Fulgurotherium
''Fulgurotherium'' (meaning "Lightning beast") is the name given to a genus of ornithischian dinosaur from the Late Cretaceous (Cenomanian) Griman Creek Formation. It lived in what is now Australia. Etymology The genus name is derived from Latin ''fulgur'', "lightning", and Greek ''therion'', "beast", a reference to the Lightning Ridge site in New South Wales. The specific name means "southern" in Latin. Its name is an unusual example of a name in which -''therium'' was used for an animal which is not an extinct mammal. History and classification The holotype of ''Fulgurotherium australe'' was first mention by British paleontologist Arthur Smith Woodward in 1909 along with several more fossils in the collection of the British Museum that had been collected from the Cenomanian Griman Creek Formation strata in Lightning Ridge in New South Wales, Australia.Agnolin, F.

Rhaetian
The Rhaetian is the latest age of the Triassic Period (in geochronology) or the uppermost stage of the Triassic System (in chronostratigraphy). It was preceded by the Norian and succeeded by the Hettangian (the lowermost stage or earliest age of the Jurassic). The base of the Rhaetian lacks a formal GSSP, though candidate sections include Steinbergkogel in Austria (since 2007) and Pignola-Abriola in Italy (since 2016). The end of the Rhaetian (and the base of the overlying Hettangian Stage) is more well-defined. According to the current ICS (International Commission on Stratigraphy) system, the Rhaetian ended ± 0.2 Ma (million years ago). In 2010, the base of the Rhaetian (i.e. the Norian-Rhaetian boundary) was voted to be defined based on the first appearance of '' Misikella posthernsteini'', a marine conodont. However, there is still much debate over the age of this boundary, as well as the evolution of ''M. posthernsteini''. The most comprehensive source of precise age ...

Dolichosuchus
''Dolichosuchus'' (meaning "long crocodile") is the name given to a genus of dinosaur from the Triassic. It was originally classified in the disused family Hallopodidae, but has since been reclassified as a coelophysoid. A single fossil (consisting of a single lower leg bone, or tibia) was found in Germany. Since only one bone was discovered, the genus is considered a '' nomen dubium''. Some scientists have noted that the tibia closely resembles those of '' Liliensternus'' and ''Dilophosaurus''.Rauhut and Hungerbuhler (2000). "A review of European Triassic theropods." ''Gaia'', 15: 75-88. The type species is ''D. cristatus'', described by Huene in 1932. The bone was recovered from the Lower Lower may refer to: *Lower (surname) *Lower Township, New Jersey *Lower Receiver (firearms) *Lower Wick Gloucestershire, England See also *Nizhny Nizhny (russian: Ни́жний; masculine), Nizhnyaya (; feminine), or Nizhneye (russian: Ни́ ... or Middle Stubensandstein formation.Hue ...

Teinurosaurus
''Teinurosaurus'' (meaning "extended tail lizard") is a genus of carnivorous theropod dinosaur. ''Teinurosaurus'' lived during the Late Jurassic in what is now France. The type species is ''Teinurosaurus sauvagei''. It's been estimated to be 11.4 m (37.4 ft) in length and 3.6 tonnes (~4 short tons) in weight. Discovery and taxonomy The holotype was discovered in 1897. Also in 1897, French paleontologist Henri-Émile Sauvage referred a tail vertebra from the Tithonian Mont-Lambert Formation of France, catalogued in the collection of the Musée Géologique du Boulonnais at Boulogne-sur-Mer in France, to '' Iguanodon prestwichii'' (now ''Cumnoria prestwichii''), a herbivorous iguanodont. In 1928 Baron Franz Nopcsa recognised the fossil to be the vertebra of a theropod not an ornithopod. He decided to name it as the genus ''Teinurosaurus''. The name is derived from Greek ''teinein'', "to stretch", and ''oura'', "tail", referring to the elongated form. However, by a mistake of the ...

Kimmeridgian
In the geologic timescale, the Kimmeridgian is an age in the Late Jurassic Epoch and a stage in the Upper Jurassic Series. It spans the time between 157.3 ± 1.0 Ma and 152.1 ± 0.9 Ma (million years ago). The Kimmeridgian follows the Oxfordian and precedes the Tithonian. Stratigraphic definition The Kimmeridgian Stage takes its name from the village of Kimmeridge on the Dorset coast, England. The name was introduced into the literature by French geologist Alcide d'Orbigny in 1842. The Kimmeridge Clay Formation takes its name from the same type location (although this formation extends from the Kimmeridgian stage of the Upper Jurassic into the Lower Cretaceous). It is the source for about 95% of the petroleum in the North Sea. Historically, the term Kimmeridgian has been used in two different ways. The base of the interval is the same but the top was defined by British stratigraphers as the base of the Portlandian (''sensu anglico'') whereas in France the top was defined as t ...

Betasuchus By Jonagold2000-d9vf4gw
''Betasuchus'' is a genus of theropod dinosaur which lived during the Late Cretaceous Period. ''Betasuchus'' is, besides ''Orthomerus'', the only dinosaur genus named from remains found in the Netherlands and the only non-avian theropod found in the Maastrichtian Beds. Discovery Its fossil, holotype BMNH 42997 (now NHM R 42997), a part of a right femur, 312 mm long, was found in the Netherlands near Maastricht, and originally described as a new species of ''Megalosaurus'' in 1883 by Harry Seeley: ''M. bredai'', honouring the late Dutch biologist and geologist Jacob Gijsbertus Samuël van Breda, a director of the Teylers Museum, who had collected the fossil at some time between 1820 and 1860 from the chalkstone quarry at the St Pietersberg. Van Breda did not excavate the remains himself but bought them from quarry workers who in this period dug stone from tunnels at several levels in the mountain; it is therefore impossible to determine the exact temporal horizon, apart from ...

Abelisaur
Abelisauroidea is typically regarded as a Cretaceous group, though the earliest abelisauridae remains are known from the Middle Jurassic of Argentina (classified as the species Eoabelisaurus mefi) and possibly Madagascar (fragmentary remains of an unnamed species) possible abelisauridae remains (an isolated left tibia, right femur, and right tibia) were also discovered in Late Jurassic Tendaguru Beds in Tanzania. Abelisauroids flourished in the Southern hemisphere during the Cretaceous period, but their origins can be traced back to at least the Middle Jurassic, when they had a more global distribution (the earliest known abelisauroid remains come from Australian and South American deposits dated to about 170 million years ago). By the Cretaceous period, abelisauroids had apparently become extinct in Asia and North America, possibly due to competition from tyrannosauroids. However, advanced abelisauroids of the family Abelisauridae persisted in the southern continents until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maastrichtian Beds
The Maastrichtian () is, in the ICS geologic timescale, the latest age (uppermost stage) of the Late Cretaceous Epoch or Upper Cretaceous Series, the Cretaceous Period or System, and of the Mesozoic Era or Erathem. It spanned the interval from . The Maastrichtian was preceded by the Campanian and succeeded by the Danian (part of the Paleogene and Paleocene). The Cretaceous–Paleogene extinction event (formerly known as the Cretaceous–Tertiary extinction event) occurred at the end of this age. In this mass extinction, many commonly recognized groups such as non-avian dinosaurs, plesiosaurs and mosasaurs, as well as many other lesser-known groups, died out. The cause of the extinction is most commonly linked to an asteroid about wide colliding with Earth, ending the Cretaceous. Stratigraphic definitions Definition The Maastrichtian was introduced into scientific literature by Belgian geologist André Hubert Dumont in 1849, after studying rock strata of the Chalk Group clo ...
