Camptosaurus2
''Camptosaurus'' ( ) is a genus of plant-eating, beaked ornithischian dinosaurs of the Late Jurassic period of western North America and possibly also Europe. The name means 'flexible lizard' ( Greek (') meaning 'bent' and (') meaning 'lizard'). Description ''Camptosaurus'' is a relatively heavily built form, with robust hindlimbs and broad feet, still having four toes. Due to the separate status of '' Uteodon'' it has become problematic which material from the Morrison Formation belongs to ''Camptosaurus''. The specimens with certainty belonging to ''Camptosaurus dispar'', from Quarry 13, have been recovered from very deep layers, probably dating to the Callovian- Oxfordian. The largest fragments from later strata indicate adult individuals more than long, and at the hips. The Quarry 13 individuals are smaller though. They have been described as reaching 6 meters (19.7 feet) in length and 785 – 874 kg in weight.Foster, J. (2007). "''Camptosaurus dispar''." ...

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] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sacral Vertebrae
The sacrum (plural: ''sacra'' or ''sacrums''), in human anatomy, is a large, triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1S5) between ages 18 and 30. The sacrum situates at the upper, back part of the pelvic cavity, between the two wings of the pelvis. It forms joints with four other bones. The two projections at the sides of the sacrum are called the alae (wings), and articulate with the ilium at the L-shaped sacroiliac joints. The upper part of the sacrum connects with the last lumbar vertebra (L5), and its lower part with the coccyx (tailbone) via the sacral and coccygeal cornua. The sacrum has three different surfaces which are shaped to accommodate surrounding pelvic structures. Overall it is concave (curved upon itself). The base of the sacrum, the broadest and uppermost part, is tilted forward as the sacral promontory internally. The central part is curved outward toward the posterior, allowing greater room for the pelv ... [...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 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 ...

Euornithopoda
Ornithopoda () is a clade of ornithischian dinosaurs, called ornithopods (), that started out as small, bipedal running grazers and grew in size and numbers until they became one of the most successful groups of herbivores in the Cretaceous world, dominating the North American land. Their major evolutionary advantage was the progressive development of a chewing apparatus that became the most sophisticated ever developed by a non-avian dinosaur, rivaling that of modern mammals such as the domestic cow. They reached their apex of diversity and ecological dominance in the hadrosaurids (colloquially known as 'duck-bills'), before they were wiped out by the Cretaceous–Paleogene extinction event along with all other non-avian dinosaurs. Members are known from all seven continents, though they are generally rare in the Southern Hemisphere. History of research In 1870, Thomas Henry Huxley listed Iguanodontidae (coined by Cope a year earlier) as one of his three families of dinosaurs (a ...

Albany County, Wyoming
Albany County ( ) is a county in the U.S. state of Wyoming. As of the 2020 United States Census, the population was 37,066. Its county seat is Laramie, the site of the University of Wyoming. Its south border lies on the northern Colorado state line. Albany County comprises the Laramie, WY Micropolitan Statistical Area. It is the fifth-most populous county in Wyoming. History Albany County was organized in 1868 of territory annexed from Laramie County in Dakota Territory, which at the time had jurisdiction over part of modern-day Wyoming. It became a county in Wyoming Territory when its government was formally organized on May 19, 1869. Charles D. Bradley, a member of the legislature of the Dakota Territory named the county for Albany, New York, the capital of his native state. In 1875, the Wyoming Territorial legislature authorized portions of Albany County to be annexed to create Crook and Johnson counties, and in 1888 land was taken from Albany County for the creation of ...

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] |
Marsh Camptosaurus
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on climate resilie ...

Dryosaurus
''Dryosaurus'' ( , meaning 'tree lizard', Greek ' () meaning 'tree, oak' and () meaning 'lizard'; the name reflects the forested habitat, not a vague oak-leaf shape of its cheek teeth as is sometimes assumed) is a genus of an ornithopod dinosaur that lived in the Late Jurassic period. It was an iguanodont (formerly classified as a hypsilophodont). Fossils have been found in the western United States and were first discovered in the late 19th century. '' Valdosaurus canaliculatus'' and '' Dysalotosaurus lettowvorbecki'' were both formerly considered to represent species of ''Dryosaurus''. Description Based on known specimens, they had been estimated to have reached up to long and to have weighed up to . However, as no known adult specimens of the genus have been found, the adult size remains unknown. In 2018, the largest specimen (CM 1949) was concluded to be from another species; revising the identity of this specimen put the previous research on size and growth into question. ...

Theiophytalia
''Theiophytalia'' is a genus of herbivorous iguanodontian dinosaur from the lower Cretaceous period (Aptian-Albian stage, about 112 million years ago) of Colorado, USA. It contains a single species, ''T. kerri''. Description Detailed comparisons by Brill and Carpenter (2006) also showed that the skull differed in a number of key features from that of ''Camptosaurus'', namely: a longer, heavier, and more rugose snout; a wider dorsal process on the maxilla; a proportionally smaller antorbital fenestra; and stouter quadrate, with a bulbous articulation for the lower jaw. Compare the skull image with that of ''Camptosaurus''. Therefore, they put it into its own genus and species. Discovery In 1878, a student of Colorado College named James Kerr found a partial Ornithopod skull at Garden of the Gods Park in El Paso County, Colorado. The skull, YPM 1887, was referred by O.C. Marsh (affirmed by Gilmore, 1909), to whom the skull was given in 1886, as that of ''Camptosaurus amplus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
