Argonauta Oweri
''Argonauta oweri'' is an extinct species of argonautid octopus. It is known from the early Pliocene of New Zealand.Saul, L.R. & C.J. Stadum (2005). Fossil argonauts (Mollusca: Cephalopoda: Octopodida) from Late Miocene siltstones of the Los Angeles Basin, California. ''Journal of Paleontology'' 79(3): 520–531. Martill, D.M. & M.J. Barker (2006). A paper nautilus (Octopoda, ''Argonauta'') from the Miocene Pakhna Formation of Cyprus. ''Palaeontology'' 49(5): 1035–1041. The type specimen, a fossilised eggcase, measures 118 mm in diameter. Its aperture is 95 mm high and 40 mm across at its widest point (though it is slightly crushed). It was collected by John R. Ower of Superior Oil Company (after whom it is named) in a " limy concretionary boulder" in Hautapu River, due west of Flat Spur and southeast of Utiku, New Zealand. The fossil was not found ''in situ'' and therefore its parent formation Formation may refer to: Linguistics * Back-formation, the pro ...

Hautapu River
Hautapu is a township in the Waipa District and Waikato region of New Zealand's North Island, located just north of Cambridge across State Highway 1. The area was identified as the Hautapu Parish on a militia farm map published in 1864 during the Waikato War, named after the Hautapu Rapids which previously occupied the site of the current Karapiro Power Station. The Hautapu Cemetery was established in June 1866. A Fonterra dairy factory is a key feature of the township. The factory was proposed in August 1884 and began processing milk on 20 December 1884 as the Cambridge Produce and Dairy Factory. In 1886, the factory was sold to new owners and was expanded to produce butter, cheese and bacon after running into problems with milk supplies. In 1901, it was sold to a new dairy co-operative which replaced the factory with a new brick factory in 1908. The factory began specialising in cheese in 1915, and came under the ownership of the new national dairy co-operative in 1919. Jas ...

Fossil Taxa Described In 1945
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, Seashell, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in #Resin, 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 stratum, 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 quantitativ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Formation (stratigraphy)
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness (geology), thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat Spur (New Zealand)
Mount Odin () is the most prominent peak, though not the highest, in the Asgard Range, of Victoria Land, Antarctica. It rises over just south of Lake Vanda. It was named by the Victoria University of Wellington Antarctic Expedition (VUWAE) (1958–59) for the Norse god Odin. Location Mount Odin lies to the south of Lake Vanda in the Wright Valley. The Odin Valley is to its east, and Obelisk Mountain to its south. Junction Knob is to the southwest. A study of soil microbiology from sites in the Odin valley down to the Onyx River in the Wright Valley, published in 1972, showed that despite the cold and dry conditions, there was active in-situ microbial life in all the soils examined. Features Features in the region around the mountain include Odin Valley, Tiw Valley, Mime Glacier, Siegfried Peak, Siegmund Peak, Heimdall Glacier, Mount Beowulf, Beowulf Glacier,, Mount Valhalla, Valhalla Glacier, Obelisk Mountain, Hind Turret, Junction Knob, Odin Glacier, Alberich Glacier, S ...

Concretion
A concretion is a hard, compact mass of matter formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. Concretions are often ovoid or spherical in shape, although irregular shapes also occur. The word 'concretion' is derived from the Latin "(act of) compacting, condensing, congealing, uniting", itself from ''con'' meaning 'together' and ''crescere'' meaning "to grow". Concretions form within layers of sedimentary strata that have already been deposited. They usually form early in the burial history of the sediment, before the rest of the sediment is hardened into rock. This concretionary cement often makes the concretion harder and more resistant to weathering than the host stratum. There is an important distinction to draw between concretions and nodules. Concretions are formed from mineral precipitation around some kind of nucleus while a nodule is a replacement body. Descriptions dating from the 18th ce ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lime (material)
Lime is a calcium-containing inorganic material composed primarily of oxides and hydroxide, usually calcium oxide and/or calcium hydroxide. It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities as building and engineering materials (including limestone products, cement, concrete, and mortar), as chemical feedstocks, and for sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for wastewater treatment with ferrous sulfate. The rocks and minerals from which these materials are derived, typ ...

Superior Oil Company
Superior Oil Company was an American oil company founded in 1921 in Coalinga, California, by William Myron Keck, Superior Oil began as a drilling contracting firm and grew into the exploration and production of oil and natural gas. In 1930 the company was the first to successfully use directional drilling in California. Moving to Houston, Texas. By 1931 the company had wells in Texas, Oklahoma, Nebraska, Louisiana and Venezuela. In 1938, the company constructed the first offshore oil platform off the coast of Louisiana in the Gulf of Mexico. In the 1970s, Superior Oil was involved in the oil shale industry developing the Superior multimineral process. In September 1984 the company, then based in Houston, became a wholly owned subsidiary of Mobil. The company was sold to Mobil Corporation in 1984, merging to it. History Background Company founder William Myron Keck, also founder of the W. M. Keck Foundation, started his career as a "roustabout" in the oil business in Pennsylvania, ...
