Acer Beckianum
''Acer beckianum'' is an extinct maple species in the family Sapindaceae described from a single fossil wood section. The species is solely known from the Middle Miocene sediments exposed in central Washington in the United States. It is one of three Washington state ''Acer'' species described in 1961 from petrified wood. Distribution and paleoenvironment The type specimen was part of a collection compiled by Jay O'Leary, who was then a student of Harvard College, in 1954 from the west bank of the Columbia River near Vantage, Washington. The petrified woods of the area are preserved in an interbed area between the older Grande Ronde Basalt and the younger Wanapum basalts, with the interbed overlain by the Ginkgo Flow, the oldest segment of the Frenchman Springs Member of the Wanapum basalts. K–Ar dating performed on the Grande Ronde Basalts gives an age of 15.6 million years old, and dating of the Frenchman Springs Member gives a date of 15.3 million years old. This places the ...

Maple
''Acer'' () is a genus of trees and shrubs commonly known as maples. The genus is placed in the family Sapindaceae.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, June 2008 nd more or less continuously updated since http://www.mobot.org/MOBOT/research/APweb/. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, ''Acer laurinum'', extends to the Southern Hemisphere.Gibbs, D. & Chen, Y. (2009The Red List of Maples Botanic Gardens Conservation International (BGCI) The type species of the genus is the sycamore maple, '' Acer pseudoplatanus'', the most common maple species in Europe.van Gelderen, C. J. & van Gelderen, D. M. (1999). ''Maples for Gardens: A Color Encyclopedia'' Maples usually have easily recognizable palmate leaves ('' Acer negundo'' is an exception) and distinctive winged fruits.

Type Specimen
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

Acer Negundo
''Acer negundo'', the box elder, boxelder maple, Manitoba maple or ash-leaved maple, is a species of maple native to North America. It is a fast-growing, short-lived tree with opposite, compound leaves. It is sometimes considered a weedy or invasive species, and has been introduced to and naturalized throughout much of the world, including in South America, Australia, New Zealand, South Africa, much of Europe, and parts of Asia. Description ''Acer negundo'' is a fast-growing and fairly short-lived tree that grows up to tall, with a trunk diameter of , rarely up to diameter. It often has several trunks and can form impenetrable thickets.van Gelderen, C.J. & van Gelderen, D.M. (1999). ''Maples for Gardens: A Color Encyclopedia''. The typical lifespan of box elder is 60 - 75 years. Under exceptionally favorable conditions, it may live to 100 years. The shoots are green, often with a whitish to pink or violet waxy coating when young. Branches are smooth, somewhat brittle, and t ...

Patronym
A patronymic, or patronym, is a component of a personal name based on the given name of one's father, grandfather (avonymic), or an earlier male ancestor. Patronymics are still in use, including mandatory use, in many countries worldwide, although their use has largely been replaced by or transformed into patronymic surnames. Examples of such transformations include common English surnames such as Johnson (son of John). Origins of terms The usual noun and adjective in English is ''patronymic'', but as a noun this exists in free variation alongside ''patronym''. The first part of the word ''patronym'' comes from Greek πατήρ ''patēr'' "father" (GEN πατρός ''patros'' whence the combining form πατρο- ''patro''-); the second part comes from Greek ὄνυμα ''onyma'', a variant form of ὄνομα ''onoma'' "name". In the form ''patronymic'', this stands with the addition of the suffix -ικός (''-ikos''), which was originally used to form adjectives with the ...

It is a subfield of historical linguistics, and draws upon comparative semantics, Morphology_(linguistics), morphology, semiotics, and phonetics. For languages with a long recorded history, written history, etymologists make use of texts, and texts about the language, to gather knowledge about how words were used during earlier periods, how they developed in Semantics, meaning and Phonological change, form, or when and how they Loanword, entered the language.

Elso Sterrenberg Barghoorn
Elso Sterrenberg Barghoorn (June 30, 1915 – January 22, 1984) was an American paleobotanist, called by his student Andrew Knoll, the present Fisher Professor of Natural History at Harvard, "the father of Pre-Cambrian palaeontology." Barghoorn is best known for discovering in South African rocks fossil evidence of life that is at least 3.4 billion years old. These fossils show that life was present on Earth comparatively soon after the Late Heavy Bombardment (about 3.8 billion years ago). Barghoorn was born in New York City. After graduating from Miami University with a BSc and an MSc in biology, Barghoorn obtained his Ph.D. in paleobotany from the Harvard University, faculty of biological sciences, in 1941. After teaching for five years at Amherst College, he joined the Harvard faculty, becoming Fisher Professor of Natural History and curator of the university's plant fossils collections. He was elected a Fellow of the American Academy of Arts and Sciences in 1950. In 1972 Ba ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
