Brontosaurus
''Brontosaurus'' (; meaning "thunder lizard" from Greek , "thunder" and , "lizard") is a genus of gigantic quadruped sauropod dinosaurs. Although the type species, ''B. excelsus'', had long been considered a species of the closely related ''Apatosaurus'' and therefore invalid, researchers proposed in 2015 that ''Brontosaurus'' is a genus separate from ''Apatosaurus'' and that it contains three species: ''B. excelsus'', ''B. yahnahpin'', and ''B. parvus''. ''Brontosaurus'' had a long, thin neck and a small head adapted for a herbivorous lifestyle, a bulky, heavy torso, and a long, whip-like tail. The various species lived during the Late Jurassic epoch, in the Morrison Formation of what is now North America, and were extinct by the end of the Jurassic.Foster, J. (2007).

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. ''Apatosaurus'' had an average length of , and an average mass of . A few specimens indicate a maximum length of 11–30% greater than average and a mass of approximately . The cervical vertebrae of ''Apatosaurus'' are less elongated and more heavily constructed than those of ''Diplodocus'', a diplodocid like ''Apatosaurus'', and the bones of the leg are much stockier despite being longer, imp ...

Othniel Charles Marsh
Othniel Charles Marsh (October 29, 1831 – March 18, 1899) was an American professor of Paleontology in Yale College and President of the National Academy of Sciences. He was one of the preeminent scientists in the field of paleontology. Among his legacies are the discovery or description of dozens of new species and theories on the origins of birds. 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 travelled 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, Cretaceous birds, and Mesozoic and Tertiary mammals that now constitute the backbone of the collections of Yale's Peabo ...

Peabody Museum Of Natural History
The Peabody Museum of Natural History at Yale University is among the oldest, largest, and most prolific university natural history museums in the world. It was founded by the philanthropist George Peabody in 1866 at the behest of his nephew Othniel Charles Marsh, the early paleontologist. Most known to the public for its Great Hall of Dinosaurs, which includes a mounted juvenile ''Brontosaurus'' and the mural '' The Age of Reptiles,'' it also has permanent exhibits dedicated to human and mammal evolution; wildlife dioramas; Egyptian artifacts; and the birds, minerals and Native Americans of Connecticut. Description The Peabody Museum is located at 170 Whitney Avenue in New Haven, Connecticut, United States, and is operated by almost one hundred staff members. While the original building was demolished in 1917, it moved to its current location in 1925, and has since expanded to occupy the Peabody Museum, the attached Kline Geology Laboratory and the Class of 1954 Environmental ...

William Harlow Reed
William Harlow Reed (9 June 1848 – 24 April 1915) was an American fossil collector and pioneer. He served as a curator at the Museum of Geology at the University of Wyoming, Laramie. He collected for a while for Othniel Charles Marsh but left after clashing with rival collectors at the height of the bone wars. Among his major finds was a near complete skeleton of a Brontosaurus (''Apatosaurus'') from Como Bluff. Reed's quarry in Como Bluff is named after him. Life and work Reed was born near Hartford, Connecticut where his father Fedelius was a cooper and millwright of Scottish origins. Reed and his family moved to Ohio in 1853 and then moved to Michigan in 1863. Reed sought to join the Union Army several times and at the end of the Civil War, he joined the Union Pacific Railroad to shovel snow but his skills at shooting were recognized, he was contracted to provide fresh meat for the railway construction workers. Reed married Florence Bovee in Michigan in 1870. He was someti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Como Bluff
Como Bluff is a long ridge extending east–west, located between the towns of Rock River and Medicine Bow, Wyoming. The ridge is an anticline, formed as a result of compressional geological folding. Three geological formations, the Sundance, the Morrison, and the Cloverly Formations, containing fossil remains from the Late Jurassic of the Mesozoic Era are exposed. Nineteenth-century paleontologists discovered many well-preserved specimens of dinosaurs, as well as mammals, turtles, crocodilians, and fish from the Morrison Formation. Because of this, Como Bluff is considered to be one of the major sites for the early discovery of dinosaur remains. Among the species discovered is the only known specimen of ''Coelurus''. Significant discoveries were made in 22 different areas scattered along the entire length of the ridge. It is included on the National Register of Historic Places as well as the National Natural Landmark list. History of discovery The discovery of dinosaurs ...

Sauropod
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include ''Brachiosaurus'', ''Diplodocus'', ''Apatosaurus'' and ''Brontosaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. ''Isanosaurus'' and ''Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the occurrence of the group in the Late Triassic. By the Late Jurassic (150 million yea ...

Dinosaurs
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among ...

Morrison Formation
The Morrison Formation is a distinctive sequence of Late Jurassic, Upper Jurassic sedimentary rock found in the western United States which has been the most fertile source of dinosaur fossils in North America. It is composed of mudstone, sandstone, siltstone, and limestone and is light gray, greenish gray, or red. Most of the fossils occur in the green siltstone beds and lower sandstones, relics of the rivers and floodplains of the Jurassic period. It is centered in Wyoming and Colorado, with outcrops in Montana, North Dakota, South Dakota, Nebraska, Kansas, the panhandles of Oklahoma and Texas, New Mexico, Arizona, Utah, and Idaho. Equivalent rocks under different names are found in Canada. It covers an area of 1.5 million square kilometers (600,000 square miles), although only a tiny fraction is exposed and accessible to geologists and Paleontology, paleontologists. Over 75% is still buried under the prairie to the east, and much of its western paleogeographic extent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of dinosau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantosaurus
''Atlantosaurus'' (meaning "Atlas lizard") is a dubious genus of sauropod dinosaur. It contains a single species, ''Atlantosaurus montanus'', from the upper Morrison Formation of Colorado, United States. ''Atlantosaurus'' was the first sauropod to be described during the infamous 19th century Bone Wars,Wilson, J. A. (2011). "Anatomical terminology for the sacrum of sauropod dinosaurs." ''Contributions from the Museum of Paleontology, University of Michigan'', 32(5): 59-69/ref> during which scientific methodology suffered in favor of pursuit of academic acclaim. History The type species, type specimen, YPM 1835, found by Arthur Lakes in Lakes Quarry Number 1 in the Morrison Formation of Colorado, United States, was named and described by Othniel Charles Marsh, Professor of Paleontology at Yale University (then called ''Yale College''), in July 1877 as ''Titanosaurus montanus''. Marsh soon learned that the name ''Titanosaurus'' had already been used earlier that year by Richard Lyd ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garden Park, Colorado
Garden Park is a paleontological site in Fremont County, Colorado, known for its Jurassic dinosaurs and the role the specimens played in the infamous Bone Wars of the late 19th century. Located north of Cañon City, the name originates from the area providing vegetables to the miners at nearby Cripple Creek in the 19th century. Garden Park proper is a triangular valley surrounded by cliffs on the southeast and southwest and by mountains to the north; however, the name is also refers to the dinosaur sites on top and along the cliffs. The dinosaur sites now form thGarden Park Paleontological Resource Area which is overseen by the Bureau of Land Management. Geology Garden Park was formed by erosion of sedimentary rocks that have been distorted by uplift of the Rocky Mountains. The region is bisected by Four Mile Creek (also called Oil Creek), which has carved a canyon through the Mesozoic and Paleozoic sedimentary rocks. One of these Mesozoic strata is the Morrison Formation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
