David Dunkle
David Hosbrook Dunkle (September 9, 1911 – January 3, 1984) was an American paleontologist. Dunkle was curator of vertebrate paleontology for the Cleveland Museum of Natural History and later associate curator for the Smithsonian Museum of Natural History. Dunkle's research and published works focused mainly on fish fossils. The genus ''Dunkleosteus'' is named in his honor. Biography Dunkle was born in Winnipeg, Manitoba, and grew up in Indiana, United States. He attended the University of Kansas and Harvard University. At Harvard, he studied under Alfred Romer and earned a PhD in 1939. Afterwards, he worked at the Cleveland Museum of Natural History (CMNH) as a curator of vertebrate paleontology. There, he studied and published papers about arthrodires from the Cleveland area. In the 1940s, he led two trips to the west to bolster the museum's collection of fossils. A notable object he collected for the museum was CMNH 7541, a dinosaur skull upon which the controversia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winnipeg
Winnipeg () is the capital and largest city of the province of Manitoba in Canada. It is centred on the confluence of the Red and Assiniboine rivers, near the longitudinal centre of North America. , Winnipeg had a city population of 749,607 and a metropolitan population of 834,678, making it the sixth-largest city, and eighth-largest metropolitan area in Canada. The city is named after the nearby Lake Winnipeg; the name comes from the Western Cree words for "muddy water" - “winipīhk”. The region was a trading centre for Indigenous peoples long before the arrival of Europeans; it is the traditional territory of the Anishinabe (Ojibway), Ininew (Cree), Oji-Cree, Dene, and Dakota, and is the birthplace of the Métis Nation. French traders built the first fort on the site in 1738. A settlement was later founded by the Selkirk settlers of the Red River Colony in 1812, the nucleus of which was incorporated as the City of Winnipeg in 1873. Being far inland, the local cl ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Dunkleosteus Juvenile Fossil - Cleveland Museum Of Natural History (34421618320)
''Dunkleosteus'' is an extinct genus of large armored, jawed fishes that existed during the Late Devonian period, about 382–358 million years ago. It consists of ten species, some of which are among the largest placoderms to have ever lived: ''D. terrelli'', ''D. belgicus'', ''D. denisoni'', ''D. marsaisi'', ''D. magnificus'', ''D. missouriensis'', ''D. newberryi'', ''D. amblyodoratus'', and ''D. raveri''. The largest and most well known species is ''D. terrelli'', which grew up to long and in weight. ''Dunkleosteus'' could quickly open and close its jaw, like modern-day suction feeders, and had a bite force of at the tip and at the blade edge. Numerous fossils of the various species have been found in North America, Poland, Belgium, and Morocco. Etymology ''Dunkleosteus'' was named in 1956 to honour David Dunkle (1911–1982), former curator of vertebrate paleontology at the Cleveland Museum of Natural History. The genus name ''Dunkleosteus'' combines David Dunkle's sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Interstate 71
Interstate 71 (I-71) is a north–south Interstate Highway in the Great Lakes/Midwestern and Southeastern region of the United States. Its southern terminus is at an interchange with I-64 and I-65 (the Kennedy Interchange) in Louisville, Kentucky, and its northern terminus at an interchange with I-90 in Cleveland, Ohio. I-71 runs concurrently with I-75 from a point about south of Cincinnati, Ohio, into Downtown Cincinnati. While most odd numbered Interstates are north–south, I-71 however is designated more of a northeast–southwest highway, with some east–west sections, and is mainly a regional route, serving Kentucky and Ohio. It links I-80 and I-90 to I-70, and ultimately (via I-65) links to I-40. Major metropolitan areas served by I-71 include Louisville, Cincinnati, Columbus, and Cleveland. Approximately three quarters of the route lie east of I-75, leaving I-71 out of place in the Interstate grid. Route description , - , KY , , - , OH , , - , Total , Kent ...

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] |
Gorgosaurus
''Gorgosaurus'' ( ; ) is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period (Campanian), between about 76.6 and 75.1 million years ago. Fossil remains have been found in the Canadian province of Alberta and the U.S. state of Montana. Paleontologists recognize only the type species, ''G. libratus'', although other species have been erroneously referred to the genus. Like most known tyrannosaurids, ''Gorgosaurus'' was a large bipedal predator, measuring in length and in body mass. Dozens of large, sharp teeth lined its jaws, while its two-fingered forelimbs were comparatively small. ''Gorgosaurus'' was most closely related to ''Albertosaurus'', and more distantly related to the larger ''Tyrannosaurus''. ''Gorgosaurus'' and ''Albertosaurus'' are extremely similar, distinguished mainly by subtle differences in the teeth and skull bones. Some experts consider ''G. libratus'' to be a species of ''Albertosaurus''; thi ... [...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] |
Nanotyrannus
''Tyrannosaurus'' is a genus of large theropod dinosaur. The species ''Tyrannosaurus rex'' (''rex'' meaning "king" in Latin), often called ''T. rex'' or colloquially ''T-Rex'', is one of the best represented theropods. ''Tyrannosaurus'' lived throughout what is now western North America, on what was then an island continent known as Laramidia. ''Tyrannosaurus'' had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the Upper Cretaceous period, 68 to 66 million years ago. It was the last known member of the tyrannosaurids and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event. Like other tyrannosaurids, ''Tyrannosaurus'' was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, the forelimbs of ''Tyrannosaurus'' were short but unusually powerful for their size, and they had two clawe ...
