Kauri (other)
''Agathis'', commonly known as kauri or dammara, is a genus of evergreen coniferous trees, native to Australasia and Southeast Asia. It is one of three extant genera in the family Araucariaceae, alongside ''Wollemia'' and ''Araucaria'' (being more closely related to the former).de Laubenfels, David J. 1988. Coniferales. P. 337–453 in Flora Malesiana, Series I, Volume 10. Dordrecht: Kluwer Academic. Its leaves are much broader than most conifers. Kauri gum is commercially harvested from New Zealand kauri. Description Mature kauri trees have characteristically large trunks, with little or no branching below the crown. In contrast, young trees are normally conical in shape, forming a more rounded or irregularly shaped crown as they achieve maturity.Whitmore, T.C. 1977. ''A first look at Agathis''. Tropical Forestry Papers No. 11. University of Oxford Commonwealth Forestry Institute. The bark is smooth and light grey to grey-brown, usually peeling into irregular flakes that ...

Karri
''Eucalyptus diversicolor'', commonly known as karri, is a species of flowering plant in the family Myrtaceae and is Endemism, endemic to the Southwest Australia, south-west of Western Australia. It is a tall tree with smooth light grey to cream-coloured, often mottled bark, lance-shaped adult leaves and barrel-shaped fruit. Found in higher rainfall areas, karri is commercially important for its timber. Description ''Eucalyptus diversicolor'' is the tallest tree that grows in Western Australia. It is a tall forest tree that typically grows to a height of but can reach as high as , making it the tallest tree in Western Australia and one of the tallest in the world. As of February 2019, the tallest known living karri is just over tall. A tree south of Pemberton, known as 'The Tyrant' is tall and in girth and contains approximately of wood in its trunk and is thought to be the largest karri by wood volume. A ''Eucalyptus diversicolor'' of height and of girth in Coimbra, Por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commonwealth Forestry Institute
The Department of Plant Sciences, at the University of Oxford, England, was a former Oxford department that researched plant and fungal biology. It was part of the university's Mathematical, Physical and Life Sciences Division. From 1 August 2022 its functionality merged with the Department of Zoology to become the Department of Biology at the University of Oxford. Herbaria The department housed the Oxford University Herbaria that consists of two herbaria: * Fielding-Druce Herbarium. * Daubeny Herbarium. In total the collections contain 800,000 specimens and benefits from close links with the university's Oxford Botanic Garden. The herbaria are now housed under the title of Department of Biology. History Forestry was an important part of the university under the name of the '' Imperial Forestry Institute'', from 1924; later the Commonwealth Forestry Institute from 1939. The Oxford Forestry Institute was incorporated into the Department of Plant Sciences in 2002, and resea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligocene
The Oligocene ( ) is a geologic epoch (geology), epoch of the Paleogene Geologic time scale, Period that extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from Ancient Greek (''olígos'') 'few' and (''kainós'') 'new', and refers to the sparsity of Neontology, extant forms of Mollusca, molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major chang ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aptian
The Aptian is an age (geology), age in the geologic timescale or a stage (stratigraphy), stage in the stratigraphic column. It is a subdivision of the Early Cretaceous, Early or Lower Cretaceous epoch (geology), Epoch or series (stratigraphy), Series and encompasses the time from 121.4 ± 1.0 annum, Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western Europe, Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 annum, Ma and lasted approximately 1 to 1.3 million years, being marked by enhanced silicate weathering, as well as ocean acidification. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma. Stratigraphic definitions The Aptian was named after the small city o ...

Lefipán Formation
The Lefipán Formation is a Maastrichtian to Danian, straddling the Cretaceous-Paleogene boundary, geologic Formation (geology), formation of the Cañadón Asfalto Basin in Chubut Province, Patagonia, Argentina. The up to thick stratigraphic unit comprises mudstones, sandstones, siltstones and conglomerate (geology), conglomerates, sourced from the North Patagonian Massif and deposited in a river delta, deltaic to shallow marine depositional environment, environment with a strong tide, tidal influence. The basin that in those times was connected to the widening Atlantic Ocean#South Atlantic, South Atlantic Ocean with a seaway connection to the Magallanes Basin, Austral Basin and possibly with the Pacific Ocean. The formation has provided unique fossil flora assemblages dating to the Cretaceous and Paleogene ages, and are characteristic of the early Cenozoic after the extinction of the dinosaurs. The occurrence of the same taxa in the Maastrichtian and Danian successions suggests t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Barkcloth
Barkcloth or bark cloth is a versatile material that was once common in Asia, Africa, and the Pacific. Barkcloth comes primarily from trees of the family Moraceae, including '' Broussonetia papyrifera'', '' Artocarpus altilis'', '' Artocarpus tamaran'', and '' Ficus natalensis''. It is made by beating sodden strips of the fibrous inner bark of these trees into sheets, which are then finished into a variety of items. Many texts that mention "paper clothing" are actually referring to barkcloth. Some modern cotton-based fabrics are also named "barkcloth" for their resemblance to these traditional fabrics. Traditional Austronesia Before the development of woven textiles, barkcloth made from trees belonging to the mulberry family ( Moraceae) were an important aspect of the pre-Austronesian and Austronesian material culture during the Neolithic period. Stone barkcloth beaters, in particular, are considered part of the "Austronesian toolkit." They have been found in abundance i ...

Patu
A patu is a club or pounder used by the Māori. The word in the Māori language means to strike, hit, beat, kill or subdue. Weapons These types of short-handled clubs were mainly used as a striking weapon. The blow administered with this weapon was a horizontal thrust straight from the shoulder at the enemy's temple. If the foe could be grasped by the hair then the patu would be driven up under the ribs or jaw. Patu were made from hardwood, whale bone, or stone. The most prestigious material for the patu was pounamu (greenstone). Māori decorated the patu by carving into the wood, bone or stone. Types of patu include: * '' patu pounamu'' or '' mere'': made from pounamu (greenstone). * ''patu onewa'': made of stone. These resemble the mere in outline but thicker, because the stone used was more easily broken than the resilient pounamu. * ''patu paraoa'': made of whale bone * ''patu tawaka'' and ''patuki'': made from wood. Other styles of short-handled wooden clubs include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Māori People
Māori () are the Indigenous peoples of Oceania, indigenous Polynesians, Polynesian people of mainland New Zealand. Māori originated with settlers from East Polynesia, who arrived in New Zealand in several waves of Māori migration canoes, canoe voyages between roughly 1320 and 1350. Over several centuries in isolation, these settlers developed Māori culture, a distinct culture, whose language, mythology, crafts, and performing arts evolved independently from those of other eastern Polynesian cultures. Some early Māori moved to the Chatham Islands, where their descendants became New Zealand's other indigenous Polynesian ethnic group, the Moriori. Early contact between Māori and Europeans, starting in the 18th century, ranged from beneficial trade to lethal violence; Māori actively adopted many technologies from the newcomers. With the signing of the Treaty of Waitangi, Treaty of Waitangi/Te Tiriti o Waitangi in 1840, the two cultures coexisted for a generation. Rising ten ...

Go Equipment
Go equipment refers to the board, stones (playing pieces), and bowls for the stones required to play the game of Go (game), Go. The quality and materials used in making Go equipment varies considerably, and the cost varies accordingly from economical to extremely expensive. History The oldest known surviving Go equipment is a board carved from rock that dates from the Han dynasty in China. Other examples of ancient equipment can be found in museums in Japan and Korea. Equipment Board The Go board, called the ''goban'' in Japanese language, Japanese, is the playing surface on which to place the stones. The standard board is marked with a 19×19 grid. Smaller boards include a 13×13 grid and a 9×9 grid used for shorter games that are often used to teach beginners. Some 19×19 boards have a 13×13 grid on the reverse side. 17×17 was used in historical times. Chinese boards are generally square; Japanese and Korean boards are slightly longer than wide, so that they for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
