Timeline Of Ceratopsian Research
This timeline of ceratopsian research is a chronological listing of events in the history of paleontology focused on the ceratopsians, a group of herbivorous marginocephalian dinosaurs that evolved parrot-like beaks, bony frills, and, later, spectacular horns. The first scientifically documented ceratopsian fossils were described by Edward Drinker Cope starting in the 1870s; however, the remains were poorly preserved and their true nature was not recognized. Over the next several decades, Cope named several such genera and species. Cope's hated rival, Othniel Charles Marsh, also described ceratopsian remains. In 1887, Marsh mistook a ''Triceratops'' horn for one belonging to a new species of prehistoric ''Bison''. Marsh also named the eponymous genus ''Ceratops'' in 1888. The next year, he named the most famous ceratopsian, ''Triceratops horridus''. It was the discovery of ''Triceratops'' that illuminated the ceratopsian body plan, and he formally named the Ceratopsia in 1890. ...

Titanoceratops
''Titanoceratops'' (meaning "titanic horned face") is a controversial genus of herbivorous ceratopsian dinosaur. It was a giant chasmosaurine ceratopsian that lived in the Late Cretaceous period (Campanian stage, about 75 million years agoFowler, D. W. 2017. Revised geochronology, correlation, and dinosaur stratigraphic ranges of the Santonian-Maastrichtian (Late Cretaceous) formations of the Western Interior of North America. PLoS ONE 12(11): e0188426.) in what is now New Mexico. ''Titanoceratops'' was named for its large size, being one of the largest known horned dinosaurs and the type species was named ''T. ouranos'', after Uranus (Ouranos), the father of the Greek titans. It was named in 2011 by Nicholas R. Longrich for a specimen previously referred to ''Pentaceratops''. Longrich believed that unique features found in the skull reveal it to have been a close relative of ''Triceratops'', classified within the subgroup Triceratopsini. However, other researchers have expresse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eponymous
An eponym is a person, a place, or a thing after whom or which someone or something is, or is believed to be, named. The adjectives which are derived from the word eponym include ''eponymous'' and ''eponymic''. Usage of the word The term ''eponym'' functions in multiple related ways, all based on an explicit relationship between two named things. A person, place, or thing named after a particular person share an eponymous relationship. In this way, Elizabeth I of England is the eponym of the Elizabethan era. When Henry Ford is referred to as "the ''eponymous'' founder of the Ford Motor Company", his surname "Ford" serves as the eponym. The term also refers to the title character of a fictional work (such as Rocky Balboa of the ''Rocky'' film series), as well as to ''self-titled'' works named after their creators (such as the album ''The Doors'' by the band the Doors). Walt Disney created the eponymous Walt Disney Company, with his name similarly extended to theme parks such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roy Chapman Andrews
Roy Chapman Andrews (January 26, 1884 – March 11, 1960) was an American explorer, adventurer and naturalist who became the director of the American Museum of Natural History. He led a series of expeditions through the politically disturbed China of the early 20th century into the Gobi Desert and Mongolia. The expeditions made important discoveries and brought the first-known fossil dinosaur eggs to the museum. Chapman's popular writing about his adventures made him famous. Biography Early life and education Andrews was born on January 26, 1884, in Beloit, Wisconsin. As a child, he explored forests, fields, and waters nearby, developing marksmanship skills. He taught himself taxidermy and used funds from this hobby to pay tuition to Beloit College. After graduating, Andrews applied for work at the American Museum of Natural History in New York City. He so much wanted to work there that after being told that there were no openings at his level, Andrews accepted a job as a jani ...

Chasmosaurus
''Chasmosaurus'' ( ) is a genus of ceratopsid dinosaur from the Upper Cretaceous Period of North America. Its name means 'opening lizard', referring to the large openings ( fenestrae) in its frill (Greek ''chasma'' meaning 'opening' or 'hollow' or 'gulf' and ''sauros'' meaning 'lizard'). With a length of and a weight of , ''Chasmosaurus'' was a ceratopsian of average size. Like all ceratopsians, it was purely herbivorous. It was initially to be called ''Protorosaurus'', but this name had been previously published for another animal. All specimens of ''Chasmosaurus'' were collected from the Dinosaur Park Formation of the Dinosaur Provincial Park of Alberta, Canada. Referred specimens of ''C. russelli'' come from the lower beds of the formation while ''C. belli'' comes from middle and upper beds. Discovery and species In 1898, at ''Berry Creek'', Alberta, Lawrence Morris Lambe of the Geological Survey of Canada made the first discovery of ''Chasmosaurus'' remains; holotype NMC 4 ...

Styracosaurus
''Styracosaurus'' ( ; meaning "spiked lizard" from the Ancient Greek / "spike at the butt-end of a spear-shaft" and / "lizard") is a genus of herbivorous ceratopsian dinosaur from the Cretaceous Period (Campanian stage), about 75.5 to 74.5 million years ago. It had four to six long parietal spikes extending from its neck frill, a smaller jugal horn on each of its cheeks, and a single horn protruding from its nose, which may have been up to long and wide. The function or functions of the horns and frills have been debated for many years. ''Styracosaurus'' was a relatively large dinosaur, reaching lengths of and weighing about . It stood about tall. ''Styracosaurus'' possessed four short legs and a bulky body. Its tail was rather short. The skull had a beak and shearing cheek teeth arranged in continuous dental batteries, suggesting that the animal sliced up plants. Like other ceratopsians, this dinosaur may have been a herd animal, travelling in large groups, as sugges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrosaurus
''Centrosaurus'' ( ; ) is a genus of herbivorous ceratopsian dinosaur from the Late Cretaceous of Canada. Their remains have been found in the Dinosaur Park Formation, dating from 76.5 to 75.5 million years ago. Discovery and naming The first ''Centrosaurus'' remains were discovered and named by paleontologist Lawrence Lambe in strata along the Red Deer River in Alberta, Canada. The name ''Centrosaurus'' means "pointed lizard" (from Greek ', , "point or prickle" and ', , "lizard"), and refers to the series of small hornlets placed along the margin of their frills, not to the nasal horns (which were unknown when the dinosaur was named). The genus is not to be confused with the stegosaur ''Kentrosaurus'', the name of which is derived from the same Greek word. Later, vast bonebeds of ''Centrosaurus'' were found in Dinosaur Provincial Park, also in Alberta. Some of these beds extend for hundreds of meters and contain thousands of individuals of all ages and all levels of complet ...

Monograph
A monograph is a specialist work of writing (in contrast to reference works) or exhibition on a single subject or an aspect of a subject, often by a single author or artist, and usually on a scholarly subject. In library cataloging, ''monograph'' has a broader meaning—that of a nonserial publication complete in one volume (book) or a definite number of volumes. Thus it differs from a serial or periodical publication such as a magazine, academic journal, or newspaper. In this context only, books such as novels are considered monographs.__FORCETOC__ Academia The English term "monograph" is derived from modern Latin "monographia", which has its root in Greek. In the English word, "mono-" means "single" and "-graph" means "something written". Unlike a textbook, which surveys the state of knowledge in a field, the main purpose of a monograph is to present primary research and original scholarship ascertaining reliable credibility to the required recipient. This research is prese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Bell Hatcher
John Bell Hatcher (October 11, 1861 – July 3, 1904) was an American paleontologist and fossil hunter known as the "king of collectors" and best known for discovering ''Torosaurus'' and ''Triceratops'', two genera of dinosaurs described by Othniel Charles Marsh. He was part of a new, professional middle class in American science, having financed his education with his labor while also being more educated than older fossil collectors. As such, he faced unique challenges throughout his long and productive career. Early life Hatcher was born on October 11, 1861 in Cooperstown, Illinois to John B. Hatcher (b. 1835) and Margaret Columbia O'Neal (b. 1842). When Hatcher was young, his father, who was both a farmer and a schoolteacher, moved the family to Cooper, Iowa. There he received his early education from his father and local schools. Education He first took an interest in paleontology and geology while working as a coal miner to save money for school and discovering fossils of ...

20th Century
The 20th (twentieth) century began on January 1, 1901 ( MCMI), and ended on December 31, 2000 ( MM). The 20th century was dominated by significant events that defined the modern era: Spanish flu pandemic, World War I and World War II, nuclear weapons, nuclear power and space exploration, nationalism and decolonization, technological advances, and the Cold War and post-Cold War conflicts. These reshaped the political and social structure of the globe. The 20th century saw a massive transformation of humanity's relationship with the natural world. Global population, sea level rise, and ecological collapses increased while competition for land and dwindling resources accelerated deforestation, water depletion, and the mass extinction of many of the world's species and decline in the population of others. Global heating increased the risk of extreme weather conditions. Additional themes include intergovernmental organizations and cultural homogenization through developments in em ...
