Camarasaurus Lentus
''Camarasaurus lentus'' is an extinct species of sauropod dinosaur that lived during the Jurassic period in what is now the western United States. It is one of the four valid species of the well-known genus ''Camarasaurus''. ''C. lentus'' fossils have been found in Wyoming, Colorado, and Utah. It is the species of ''Camarasaurus'' found in Dinosaur National Monument and the middle layers of the Morrison Formation. ''Camarasaurus lentus'' is among the best-known sauropod species, with many specimens known. A juvenile specimen of ''C. lentus'', CM 11338, is the most complete sauropod fossil ever discovered. Description Like other sauropods, ''Camarasaurus lentus'' was a large, long-necked quadruped. It closely resembled other species of ''Camarasaurus'' in its anatomy, and in particular was very similar to ''C. supremus''. It was of moderate size for the genus, being similar in size to ''C. grandis'', 20% smaller than ''C. supremus'', and slightly larger than ''C. lewisi''. Gregory ...

Carnegie Museum Of Natural History
The Carnegie Museum of Natural History (abbreviated as CMNH) is a natural history museum in the Oakland neighborhood of Pittsburgh, Pennsylvania. It was founded by Pittsburgh-based industrialist Andrew Carnegie in 1896. Housing some 22 million specimens, the museum features one of the finest paleontological collections in the world. Description and history The museum consists of organized into 20 galleries as well as research, library, and office space. It holds some 22 million specimens, of which about 10,000 are on view at any given time and about 1 million are cataloged in online databases. In 2008 it hosted 386,300 admissions and 63,000 school group visits. Museum education staff also actively engage in outreach by traveling to schools all around western Pennsylvania. The museum gained prominence in 1899 when its scientists unearthed the fossils of ''Diplodocus carnegii''. Notable dinosaur specimens include one of the world's very few fossils of a juvenile ''Apatosauru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Othniel 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 Peabod ...

Diplodocoidea
Diplodocoidea is a superfamily of sauropod dinosaurs, which included some of the longest animals of all time, including slender giants like ''Supersaurus'', ''Diplodocus'', ''Apatosaurus'', and ''Amphicoelias''. Most had very long necks and long, whip-like tails; however, one family (the dicraeosaurids) are the only known sauropods to have re-evolved a short neck, presumably an adaptation for feeding low to the ground. This adaptation was taken to the extreme in the highly specialized sauropod ''Brachytrachelopan''. A study of snout shape and dental microwear in diplodocoids showed that the square snouts, large proportion of pits, and fine subparallel scratches in ''Apatosaurus'', ''Diplodocus'', ''Nigersaurus'', and ''Rebbachisaurus'' suggest ground-height nonselective browsing; the narrow snouts of ''Dicraeosaurus'', ''Suuwassea'', and ''Tornieria'' and the coarse scratches and gouges on the teeth of ''Dicraeosaurus'' suggest mid-height selective browsing in those taxa.John A.

Neosauropoda
Neosauropoda is a clade within Dinosauria, coined in 1986 by Argentine paleontologist José Bonaparte and currently described as ''Saltasaurus loricatus'', ''Diplodocus longus'', and all animals directly descended from their most recent common ancestor. The group is composed of two subgroups: Diplodocoidea and Macronaria. Arising in the early Jurassic and persisting until the Cretaceous-Paleogene extinction event, Neosauropoda contains the majority of sauropod genera, including genera such as ''Apatosaurus'', ''Brachiosaurus'', and ''Diplodocus''. It also includes giants such as '' Argentinosaurus'', '' Patagotitan'' and '' Sauroposeidon'', and its members remain the largest land animals ever to have lived. When Bonaparte first coined the term Neosauropoda in 1986, he described the clade as comprising “end-Jurassic” sauropods. While Neosauropoda does appear to have originated at the end of the Jurassic period, it also includes members throughout the Cretaceous. Neosaurop ...

Turiasauria
Turiasauria is an unranked clade of basal sauropod dinosaurs known from Middle Jurassic to Early Cretaceous deposits in Europe, North America, and Africa. Description Turiasauria was originally erected by Royo-Torres et al. (2006) to include ''Turiasaurus'', ''Galveosaurus'' and ''Losillasaurus'', all of which hail from the Villar del Arzobispo Formation (Tithonian-Berriasian) of Spain. Turiasuria was defined by the authors as "all Eusauropoda closer to ''Turiasaurus riodevensis'' than to ''Saltasaurus loricatus''". Cladistic analysis (Royo-Torres ''et al.'', 2006; 1927) of 309 characters and 33 taxa suggests that the turiasaurians lie outside the Neosauropoda and form a monophyletic group. The clade is diagnosed by the presence of vertical neural spines, posterior centroparapohyseal laminae on the dorsal vertebrae, the absence of pre- and postspinal laminae on the dorsal vertebrae, the absence of a scapular acromial crest, the presence of a prominent humeral deltopectoral crest, ...

Mamenchisauridae
Mamenchisauridae is a family of sauropod dinosaurs belonging to Eusauropoda known from the Jurassic and Early Cretaceous of Asia and Africa. Some members of the group reached gigantic sizes, amongst the largest of all sauropods. Classification The family Mamenchisauridae was first erected by Chinese paleontologists Yang Zhongjian ("C.C. Young") and Zhao Xijin in 1972, in a paper describing '' Mamenchisaurus hochuanensis''.Young, C.C. and Zhao, X. (1972). "''Mamenchisaurus hochuanensis sp. nov.''". ''Institute of Vertebrate Palaeontology and Palaeoanthropology Monographs'' Series A 8: 1-30. The most complete cladogram of Mamenchisauridae is presented by Moore ''et al.'', 2020, which includes several named species. Notably, some iterations of their analysis recover ''Euhelopus'' and kin, usually considered somphospondylians, as relatives of mamenchisaurids, mirroring earlier conceptions about the family.

Shunosaurus
''Shunosaurus'', meaning "shu lizard", is a genus of sauropod dinosaur from Late Jurassic ( Oxfordian) beds in Sichuan Province in China, approximately 159±2 million years ago. The name derives from "Shu", an ancient name for the Sichuan province. Discovery and species The first fossil of ''Shunosaurus'' was discovered in 1977 by a group of students, practising paleontological excavation at a road bank. The type species, ''Shunosaurus lii'', was described and named by Dong Zhiming, Zhou Shiwu and Zhang Yihong in 1983. The generic name derives from "Shu", an ancient name for Sichuan. The specific name honours hydrologist Li Bing, the governor of Sichuan in the third century BC. The holotype, IVPP V.9065, was collected from the Lower Xiashaximiao Formation near Dashanpu, Zigong. It consists of a partial skeleton. Later about twenty more major specimens were discovered, including several complete or near-complete skeletons, skulls and juveniles, making ''Shunosaurus'' on ...

Quarry Visitor Center
Quarry Visitor Center, in Dinosaur National Monument in Utah was built as part of the National Park Service's Mission 66 program of modern architectural design in the US national parks. This visitor center exemplifies the philosophy of locating visitor facilities immediately at the resource being interpreted. The visitor center was closed from 2006 to 2011 due to structural damage from unstable soils. The rotunda structure was demolished and replaced with a new structure of different design, while the quarry section was being stabilized and repaired. Design The visitor center was built in part to attract visitors to the little-visited monument, which had been threatened with flooding by the Echo Park Dam, as a means of guarding against renewed reservoir proposals. The visitor center's concept was first expressed in 1916 when George Otis Smith, the director of the U.S. Geological Survey, suggested that the specimens be displayed in the northern canyon wall.

Wyoming Dinosaur Center
The Wyoming Dinosaur Center is located in Thermopolis, Wyoming and is one of the few dinosaur museums in the world to have excavation sites within driving distance. The museum displays the Thermopolis Specimen of ''Archaeopteryx'', which is the only real specimen of this genus on display outside of Europe. Fifteen minutes from the museum are their many dig sites. Located on the Warm Springs Ranch, more than 10,000 bones have been discovered and excavated, most of which are either on display or stored just down the hill at the museum. One of the most notable fossil assemblies on the property is from the "Something Interesting" or SI excavation site. This site presents the rare occurrence of both dinosaur trace fossils and body fossils including footprints of many Sauropods and ''Allosaurus'' as well as skeletal remains from '' Camarasaurus, Diplodocus,'' and ''Apatosaurus'' - three of the sauropods most common in the area during the Late Jurassic. Most of the bones belong to a juven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Jacob Holland
Rev William Jacob Holland FRSE LLD (August 16, 1848 – December 13, 1932) was the eighth Chancellor of the University of Pittsburgh (1891–1901) and Director of the Carnegie Museums of Pittsburgh. He was an accomplished zoologist and paleontologist, as well as an ordained Presbyterian minister. Life Holland was born August 16, 1848 in Jamaica, West Indies, the son of Rev Francis R Holland and his wife, Eliza Augusta Wolle. He spent his early years in Salem, North Carolina, later attending Nazareth Hall, a Moravian boys' school in Pennsylvania, followed by Amherst College, (A.B., 1869), and Princeton Theological Seminary (1874). At Amherst Holland's roommate was a student from Japan, causing Holland to become interested in Japanese and to learn that language well before it was a common pursuit in the United States. In 1874 he moved to Pittsburgh, Pennsylvania to become pastor of the Bellefield Presbyterian Church in the city's Oakland neighborhood. At this time Holland was also ...

Charles W
The F/V ''Charles W'', also known as Annie J Larsen, is a historic fishing schooner anchored in Petersburg, Alaska. At the time of its retirement in 2000, it was the oldest fishing vessel in the fishing fleet of Southeast Alaska, and the only known wooden fishing vessel in the entire state still in active service. Launched in 1907, she was first used in the halibut fisheries of Puget Sound and the Bering Sea as the ''Annie J Larsen''. In 1925 she was purchased by the Alaska Glacier Seafood Company, refitted for shrimp trawling, and renamed ''Charles W'' in honor of owner Karl Sifferman's father. The company was one of the pioneers of the local shrimp fishery, a business it began to phase out due to increasing competition in the 1970s. The ''Charles W'' was the last of the company's fleet of ships, which numbered twelve at its height. The boat was acquired in 2002 by the nonprofit Friends of the ''Charles W''. The boat was listed on the National Register of Historic Places in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
