Betasuchus
''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 ...

Maastricht Formation
The Maastricht Formation (Dutch: ''Formatie van Maastricht''; abbreviation: MMa), named after the city of Maastricht in the Netherlands, is a geological formation in the Netherlands and Belgium whose strata date back to the Late Cretaceous, within 500,000 years of the Cretaceous–Paleogene boundary, now dated at . The formation is part of the Chalk Group and is between thick. It crops out in southern parts of Dutch and Belgian Limburg and adjacent areas in Germany. It can be found in the subsurface of northern Belgium and southeastern Netherlands, especially in the Campine Basin and Roer Valley Graben. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, Europe)."

Megalosaurus
''Megalosaurus'' (meaning "great lizard", from Greek , ', meaning 'big', 'tall' or 'great' and , ', meaning 'lizard') is an extinct genus of large carnivorous theropod dinosaurs of the Middle Jurassic period (Bathonian stage, 166 million years ago) of Southern England. Although fossils from other areas have been assigned to the genus, the only certain remains of ''Megalosaurus'' come from Oxfordshire and date to the late Middle Jurassic. ''Megalosaurus'' was, in 1824, the first genus of non-avian dinosaur to be validly named. The type species is ''Megalosaurus bucklandii'', named in 1827. In 1842, ''Megalosaurus'' was one of three genera on which Richard Owen based his Dinosauria. On Owen's directions a model was made as one of the Crystal Palace Dinosaurs, which greatly increased the public interest for prehistoric reptiles. Over fifty other species would eventually be classified under the genus; at first, this was because so few types of dinosaur had been identified, but the p ...

Jacob Gijsbertus Samuël Van Breda
Jacob Gijsbertus Samuël van Breda (24 October 1788, in Delft – 2 September 1867, in Haarlem) was a Dutch biologist and geologist. Jacob was the son of Jacob van Breda, a Dutch physician, physicist and politician, and Anna Elsenera van Campen. His mother died when he was two years old. He studied medicine and physics at the University of Leyden, where he obtained his degree in medicine and philosophy in 1811, afterwards he travelled to Paris. In 1816 he became professor of botany, chemistry and pharmacy at the University of Franeker. In this period he benefitted from the newly peaceful conditions in Europe by visiting places of scientific interest to him, e.g. in Germany. At Franeker he became close personal friends with one of the curators, the Dutch lawyer, administrator and politician Squire Adriaan Gillis Camper, himself the son of professor of anatomy Petrus Camper. On 9 May 1821 he married in Klein Lankum with Camper's third child and second daughter Frederika Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Pietersberg
Mount Saint Peter ( French: ''Montagne Saint-Pierre''; Dutch: ''Sint-Pietersberg''), also referred to as Caestert Plateau, is the northern part of a plateau running north to south between the valleys of the river Geer to the west, and the Meuse to the east. The plateau runs from Maastricht in the Netherlands, through Riemst in Belgian Limburg almost to the city of Liège in Belgium, thus defining the topography of this border area between Flanders, Wallonia and the Netherlands. The name of the hill, as well as the nearby village and church of Sint Pieter and the fortress of Sint Pieter, refers to Saint Peter, one of the Twelve Apostles. Principal characteristics The plateau, of which Mount Saint Peter is part, is bounded on the east by the Meuse river (Dutch: ''Maas'') and on the west by the Geer (''Jeker''). Since the 1930s, the Albert Canal divides the hill in two sections. Near the small Liège Province village of Lanaye (Dutch: ''Ternaaien''), the canal cuts through the ri ...

British Museum Of Natural History
The Natural History Museum in London is a museum that exhibits a vast range of specimens from various segments of natural history. It is one of three major museums on Exhibition Road in South Kensington, the others being the Science Museum and the Victoria and Albert Museum. The Natural History Museum's main frontage, however, is on Cromwell Road. The museum is home to life and earth science specimens comprising some 80 million items within five main collections: botany, entomology, mineralogy, palaeontology and zoology. The museum is a centre of research specialising in taxonomy, identification and conservation. Given the age of the institution, many of the collections have great historical as well as scientific value, such as specimens collected by Charles Darwin. The museum is particularly famous for its exhibition of dinosaur skeletons and ornate architecture—sometimes dubbed a ''cathedral of nature''—both exemplified by the large ''Diplodocus'' cast that domin ...

Mosasaur
Mosasaurs (from Latin ''Mosa'' meaning the 'Meuse', and Greek ' meaning 'lizard') comprise a group of extinct, large marine reptiles from the Late Cretaceous. Their first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in 1764. They belong to the order Squamata, which includes lizards and snakes. Mosasaurs probably evolved from an extinct group of aquatic lizards known as aigialosaurs in the Earliest Late Cretaceous with 42 described genera. During the last 20 million years of the Cretaceous period (Turonian–Maastrichtian ages), with the extinction of the ichthyosaurs and pliosaurs, mosasaurs became the dominant marine predators. They themselves became extinct as a result of the K-Pg event at the end of the Cretaceous period, about 66 million years ago. Description Mosasaurs breathed air, were powerful swimmers, and were well-adapted to living in the warm, shallow inland seas prevalent during the Late Cretaceous period. Mosasaurs were so ...

Wastebin Taxon
Wastebasket taxon (also called a wastebin taxon, dustbin taxon or catch-all taxon) is a term used by some taxonomists to refer to a taxon that has the sole purpose of classifying organisms that do not fit anywhere else. They are typically defined by either their designated members' often superficial similarity to each other, or their ''lack'' of one or more distinct character states or by their ''not'' belonging to one or more other taxa. Wastebasket taxa are by definition either paraphyletic or polyphyletic, and are therefore not considered valid taxa under strict cladistic rules of taxonomy. The name of a wastebasket taxon may in some cases be retained as the designation of an evolutionary grade, however. The term was coined in a 1985 essay by Steven Jay Gould. Examples There are many examples of paraphyletic groups, but true "wastebasket" taxa are those that are known not to, and perhaps not intended to, represent natural groups, but are nevertheless used as convenient group ...

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Ornithomimosauria
Ornithomimosauria ("bird-mimic lizards") are theropod dinosaurs which bore a superficial resemblance to the modern-day ostrich. They were fast, omnivorous or herbivorous dinosaurs from the Cretaceous Period (geology), Period of Laurasia (now Asia, Europe and North America), as well as Africa and possibly Australia. The group first appeared in the Early Cretaceous and persisted until the Late Cretaceous. Primitive members of the group include ''Nqwebasaurus'', ''Pelecanimimus'', ''Shenzhousaurus'', ''Hexing'' and ''Deinocheirus'', the arms of which reached 2.4 m (8 feet) in length. More advanced species, members of the family Ornithomimidae, include ''Gallimimus'', ''Struthiomimus'', and ''Ornithomimus''. Some paleontologists, like Paul Sereno, consider the enigmatic Alvarezsauridae, alvarezsaurids to be close relatives of the ornithomimosaurs and place them together in the superfamily Ornithomimoidea (see classification below).

Dale Russell
Dale Alan Russell (27 December 1937 – 21 December 2019) was an American-Canadian geologist and palaeontologist. Throughout his career Russell worked as the Curator of Fossil Vertebrates at the Canadian Museum of Nature, Research Professor at the Department of Marine Earth and Atmospheric Sciences (MEAS) at North Carolina State University, and Senior Paleontologist at the North Carolina Museum of Natural Sciences. Dinosaurs he has described include '' Daspletosaurus'' and ''Dromiceiomimus'', and he was amongst the first paleontologists to consider an extraterrestrial cause (supernova, comet, asteroid) for the Cretaceous–Paleogene extinction event. Russell also helped lead the China-Canada Dinosaur Project from 1986 to 1991. In 1982, Russell created the "dinosauroid" thought experiment, which speculated an evolutionary path for ''Troodon'' if it had not gone extinct in the Cretaceous–Paleogene extinction event The Cretaceous–Paleogene (K–Pg) extinction event (als ...
