Mosasaurus
''Mosasaurus'' (; "lizard of the Meuse (river), Meuse River") is the type genus (defining example) of the mosasaurs, an extinct group of aquatic Squamata, squamate reptiles. It lived from about 82 to 66 million years ago during the Campanian and Maastrichtian Stage (stratigraphy), stages of the Late Cretaceous. The genus was one of the first Mesozoic marine reptiles known to science—the first fossils of ''Mosasaurus'' were found as skulls in a chalk quarry near the Dutch city of Maastricht in the late 18th century, and were initially thought to be crocodiles or whales. One skull discovered around 1780 was famously nicknamed the "great animal of Maastricht". In 1808, naturalist Georges Cuvier concluded that it belonged to a giant marine lizard with similarities to monitor lizards but otherwise unlike any known living animal. This concept was revolutionary at the time and helped support the then-developing ideas of extinction. Cuvier did not designate a scientific name for the an ...

Mosasaur
Mosasaurs (from Latin ''Mosa'' meaning the 'Meuse', and Ancient Greek, Greek ' meaning 'lizard') are an extinct group of large aquatic reptiles within the family Mosasauridae that lived during 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. During the last 20 million years of the Cretaceous period (Turonian–Maastrichtian ages), with the extinction of the ichthyosaurs and Pliosauridae, pliosaurs, mosasaurids became the dominant marine predators. They themselves became extinct as a result of the Cretaceous–Paleogene extinction event, 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 sea (geology), inland seas prevalent during the Late Cretaceous period. Mosasaurs were so well adapted to thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maastrichtian
The Maastrichtian ( ) is, in the International Commission on Stratigraphy (ICS) geologic timescale, the latest age (geology), age (uppermost stage (stratigraphy), stage) of the Late Cretaceous epoch (geology), Epoch or Upper Cretaceous series (stratigraphy), Series, the Cretaceous geologic period, Period or system (stratigraphy), System, and of the Mesozoic geologic era, 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). It is named after the city of Maastricht, the capital and largest city of the Limburg (Netherlands), Limburg province in the Netherlands. The Cretaceous–Paleogene extinction event (formerly known as the Cretaceous–Tertiary period, Tertiary extinction event) occurred at the end of this age. In this extinction event, mass extinction, many commonly recognized groups such as non-avian dinosaurs, plesiosaurs and mosasaurs, as well as many other lesser-kn ...

Maastricht Natural History Museum
Maastricht Natural History Museum (Dutch language, Dutch: ''Natuurhistorisch Museum Maastricht'') is a museum of natural history in Maastricht, Netherlands. The museum is located in a former monastery called ''Grauwzustersklooster'' (English: ''Monastery of the Grey Sisters'') in the historic district Jekerkwartier in the centre of Maastricht. The collection is dedicated to the geology, paleontology, Botany, flora and Zoology, fauna of South Limburg. Highlights from the collection are Cretaceous fossils from Mount Saint Peter, Sint-Pietersberg, most notably the skull of a Mosasaur (nicknamed "Bèr") and specimens of Hoffmann's giant turtle, ''Allopleuron, Allopleuron hofmanni'' and Suyckerbuyk's turtle, ''Glyptochelone suyckerbuyki''. A significant mosasaurus skull was taken by the French during the Siege of Maastricht (1794), Siege of Maastricht, and has been housed at the National Museum of Natural History, France, French National Museum of Natural History since 1794.

Richard Harlan
Richard Harlan (September 19, 1796 – September 30, 1843) was an American paleontologist, anatomist, and physician. He was the first American to devote significant time and attention to vertebrate paleontology and was one of the most important contributors to the field in the early nineteenth century. His work was noted for its focus on objective descriptions, taxonomy and nomenclature. He was the first American to routinely apply binomial Linnaean names to vertebrate and invertebrate fossils. Prior to the time of Harlan, it was common practice to publish only a genus name for a fossil animal that was new to science. Biography Harlan was born in Philadelphia on September 19, 1796, to Joshua Harlan, a wealthy Quaker merchant, and his wife Sarah Hinchman Harlan, one of their ten children. He was three years older than his brother Josiah Harlan, who would become the first American to visit Afghanistan. Harlan graduated in medicine from the University of Pennsylvania in 1818 afte ...

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontology, paleontologist, comparative anatomy, comparative anatomist, herpetology, herpetologist, and ichthyology, ichthyologist. Born to a wealthy Quaker family, he distinguished himself as a child prodigy interested in science, publishing his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the Western United States, American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey, U.S. Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. Cope's financial fortunes soured after failed mining ventures i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meuse (river)
The Meuse or Maas is a major European river, rising in France and flowing through Belgium and the Netherlands before draining into the North Sea from the Rhine–Meuse–Scheldt delta. It has a total length of . History From 1301, the upper Meuse roughly marked the western border of the Holy Roman Empire with the France in the Middle Ages, Kingdom of France, after Count Henry III, Count of Bar, Henry III of Bar had to receive the western part of the County of Bar (''Barrois mouvant'') as a French fief from the hands of King Philip IV of France, Philip IV. In 1408, a Burgundian army led by John the Fearless went to the aid of John III, Duke of Bavaria, John III against the citizens of Liège, who were in open revolt. After the Battle of Othée, battle, which saw the men from Liège defeated, John ordered the drowning in the Meuse of burghers and noblemen in Liège whose loyalties he suspected. The border remained relatively stable until the annexation of the Three Bishoprics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Georges Cuvier
Jean Léopold Nicolas Frédéric, baron Cuvier (23 August 1769 – 13 May 1832), known as Georges Cuvier (; ), was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastr ...

Snake
Snakes are elongated limbless reptiles of the suborder Serpentes (). Cladistically squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales much like other members of the group. Many species of snakes have skulls with several more joints than their lizard ancestors and relatives, enabling them to swallow prey much larger than their heads ( cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most only have one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have independently evolved elongate bodies without limbs or with greatly reduced limbs at least twenty-five times via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, althoug ...

Prey
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunistic or omnivorous and only practice predation occasionally. Most obligate carnivores are specialized for hunting. They may ha ...
