Charles W. Gilmore
Charles Whitney Gilmore (March 11, 1874 – September 27, 1945) was an American paleontologist who gained renown in the early 20th century for his work on vertebrate fossils during his career at the United States National Museum (now the National Museum of Natural History). Gilmore named many dinosaurs in North America and Mongolia, including the Cretaceous sauropod '' Alamosaurus'', '' Alectrosaurus'', '' Archaeornithomimus'', '' Bactrosaurus'', '' Brachyceratops'', '' Chirostenotes'', '' Mongolosaurus'', '' Parrosaurus'', ''Pinacosaurus'', '' Styracosaurus ovatus'' (now '' Rubeosaurus'') and ''Thescelosaurus''. Career Gilmore was working as a paleontologist for the Carnegie Museum of Natural History in 1901 when he found the skeleton of a young sauropod, which was classified the following year as an ''Apatosaurus''. In 1903 Gilmore was hired by the United States National Museum (now the National Museum of Natural History), part of the Smithsonian Institution. His first a ...

Diplodocus
''Diplodocus'' (, , or ) is an extinct genus of diplodocid sauropod dinosaurs known from the Late Jurassic of North America. The first fossils of ''Diplodocus'' were discovered in 1877 by S. W. Williston. The generic name, coined by Othniel Charles Marsh in 1878, is a Neo-Latin term derived from Greek διπλός (''diplos'') "double" and δοκός (''dokos'') "beam", in reference to the double-beamed chevron bones located in the underside of the tail, which were then considered unique. The genus of dinosaurs lived in what is now mid-western North America, at the end of the Jurassic period. It is one of the more common dinosaur fossils found in the middle to upper Morrison Formation, with most specimens being found in rocks between about 151.88 and 149.1 million years ago , during the latest Kimmeridgian Age, although it may have made it into the Tithonian., with at least one specimen (AMNH FR 223) being potentially from among the youngest deposits of the formation.

Pinacosaurus
''Pinacosaurus'' (meaning "Plank lizard") is a genus of ankylosaurid thyreophoran dinosaur that lived in Asia during the Late Cretaceous (Campanian, roughly 75 to 71 million years ago), mainly in Mongolia and China. The first remains of the genus were found in 1923, and the type species ''Pinacosaurus grangeri'' was named in 1933. ''Pinacosaurus mephistocephalus'' named in 1999, is a second possibly valid species differing from the type species in details of the skull armour. At least 24 ''Pinacosaurus'' skeletons have been found, possibly more than of any other ankylosaur. These predominantly consist of juveniles. Adult fossils have not been found in groups. ''Pinacosaurus'' was a medium-sized ankylosaurine, about long and weighed up to . Its body was flat and low-slung but not as heavily built as in some other members of the Ankylosaurinae. The head was protected by bone tiles, hence its name. Each nostril was formed as a large depression pierced by between three and five smal ...

Triceratops
''Triceratops'' ( ; ) is a genus of Chasmosaurinae, chasmosaurine Ceratopsia, ceratopsian dinosaur that lived during the late Maastrichtian age of the Late Cretaceous Period (geology), period, about 68 to 66 million years ago on the island continent of Laramidia, now forming western North America. It was one of the last-known non-avian dinosaurs and lived until the Cretaceous-Paleogene extinction event, Cretaceous–Paleogene extinction event 66 million years ago. The name ''Triceratops'', which means 'three-horned face', is derived from the Ancient Greek, Greek words () meaning 'three', () meaning 'horn', and () meaning 'face'. Bearing a large bony neck frill, frill, three horns on the skull, and a large, four-legged body, exhibiting convergent evolution with bovines and rhinoceroses, ''Triceratops'' is one of the most recognizable of all dinosaurs and the best-known ceratopsian. It was also one of the largest, measuring around long and weighing up to . It shared the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edmontosaurus
''Edmontosaurus'' ( ) (meaning "lizard from Edmonton"), with the second species often colloquially and historically known as ''Anatosaurus'' or ''Anatotitan'' (meaning "duck lizard" and "giant duck"), is a genus of hadrosaurid (duck-billed) dinosaur. It contains two known species: ''Edmontosaurus regalis'' and ''Edmontosaurus annectens''. Fossils of ''E. regalis'' have been found in rocks of western North America that date from the late Campanian Stage (stratigraphy), age of the Cretaceous Period (geology), period 73 million years ago, while those of ''E. annectens'' were found in the same geographic region from rocks dated to the end of the Maastrichtian age, 66 million years ago. ''Edmontosaurus'' was one of the last non-bird, avian dinosaurs ever to exist, and lived alongside dinosaurs like ''Triceratops'', ''Tyrannosaurus'', ''Ankylosaurus'', and ''Pachycephalosaurus'' shortly before the Cretaceous–Paleogene extinction event. ''Edmontosaurus'' included two of the lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bone Wars
The Bone Wars, also known as the Great Dinosaur Rush, was a period of intense and ruthlessly competitive fossil hunting and discovery during the Gilded Age of American history, marked by a heated rivalry between Edward Drinker Cope (of the Academy of Natural Sciences of Philadelphia) and Othniel Charles Marsh (of the Peabody Museum of Natural History at Yale). Each of the two paleontologists used underhanded methods to try to outdo the other in the field, resorting to bribery, theft, and the destruction of bones. Each scientist also sought to ruin his rival's reputation and cut off his funding, using attacks in scientific publications. Their search for fossils led them west to rich bone beds in Colorado, Nebraska, and Wyoming. From 1877 to 1892, both paleontologists used their wealth and influence to finance their own expeditions and to procure services and dinosaur bones from fossil hunters. By the end of the Bone Wars, both men had exhausted their funds in the pursuit of pale ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Othniel Charles Marsh
Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American professor of paleontology. A prolific fossil collector, Marsh was one of the preeminent paleontologists of the nineteenth century. Among his legacies are the discovery or description of dozens of new species—including the stegosaurus and triceratops—and theories on the origins of birds. He spent his academic career at Yale College and was president of the National Academy of Sciences. Born into a modest family, Marsh was able to afford higher education thanks to the generosity of his wealthy uncle George Peabody. After graduating from Yale College in 1860 he traveled the world, studying anatomy, mineralogy and geology. He obtained a teaching position at Yale upon his return. From the 1870s to 1890s, he competed with rival paleontologist Edward Drinker Cope in a period of frenzied Western American expeditions known as the Bone Wars. Marsh's greatest legacy is the collection of Mesozoic reptiles, Creta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Apatosaurus
''Apatosaurus'' (; meaning "deceptive lizard") is a genus of herbivorous sauropod dinosaur that lived in North America during the Late Jurassic period. Othniel Charles Marsh described and named the first-known species, ''A. ajax'', in 1877, and a second species, ''A. louisae'', was discovered and named by William H. Holland in 1916. ''Apatosaurus'' lived about 152 to 151 million years ago (mya), during the late Kimmeridgian to early Tithonian age, and are now known from fossils in the Morrison Formation of modern-day Colorado, Oklahoma, New Mexico, Wyoming, and Utah in the United States.
