Pelorovis Oldowayensis
''Pelorovis'' ("prodigious/monstrous sheep") is an extinct genus of African bovines which existed during the Pleistocene epoch. Originally believed to be a giant member of Caprinae, related to modern sheep, it is now known to be a relative of cattle and buffalos. The best known and type species is ''Pelorovis oldowayensis'', from the Early Pleistocene of Olduvai Gorge, Tanzania, though two others, ''P. turkanensis'' and ''P. howelli'', are currently recognised. A fourth, ''P. praeafricanus'', may exist, or it may represent the same species as ''P. oldowayensis''. "''Pelorovis''" ''antiquus'', from the Late Pleistocene-Holocene, and "P." ''kaisensis'', have since been moved into ''Syncerus'', the same genus as living African buffalo. In many respects, ''Pelorovis'' resembles the modern cattle genus, ''Bos'', and has been compared morphologically to aurochsen (''Bos primigenius''). It has been suggested that they represent the same genus, in which case ''Pelorovis'' would be a ju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism 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 and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

Syntype
In biological nomenclature, a syntype is any one of two or more biological types that is listed in a description of a taxon where no holotype was designated. Precise definitions of this and related terms for types have been established as part of the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants. In zoology In zoological nomenclature, a syntype is defined as "Each specimen of a type series (q.v.) from which neither a holotype nor a lectotype has been designated rts. 72.1.2, 73.2, 74 The syntypes collectively constitute the name-bearing type." (Glossary of the zoological Code). Historically, it was common to describe a new species or subspecies from several syntypes without designating a holotype, but this practice is generally frowned upon by modern taxonomists, and most are gradually being replaced by lectotypes. Those that still exist are still considered name-bearing types. A lectotype may be designated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camille Arambourg
Camille Arambourg (February 3, 1885 – November 19, 1969) was a French vertebrate paleontologist. He conducted extensive field work in North Africa. In the 1950s, he argued against the prevailing model of Neanderthals as brutish and simian. During World War 1, he was in Military service. After that he was a professor of Geology at the Institut Agricole d'Alger, and after that a professor of Paleontology at Muséum National d'Histoire Naturelle in Paris Paris () is the Capital city, capital and List of communes in France with over 20,000 inhabitants, largest city of France.

Horn (anatomy)
A horn is a permanent pointed projection on the head of various animals that consists of a covering of keratin and other proteins surrounding a core of live bone. Horns are distinct from antlers, which are not permanent. In mammals, true horns are found mainly among the ruminant artiodactyls, in the families Antilocapridae ( pronghorn) and Bovidae ( cattle, goats, antelope etc.). Cattle horns arise from subcutaneous connective tissue (under the scalp) and later fuse to the underlying frontal bone. One pair of horns is usual; however, two or more pairs occur in a few wild species and in some domesticated breeds of sheep. Polycerate (multi-horned) sheep breeds include the Hebridean, Icelandic, Jacob, Manx Loaghtan, and the Navajo-Churro. Horns usually have a curved or spiral shape, often with ridges or fluting. In many species, only males have horns. Horns start to grow soon after birth and continue to grow throughout the life of the animal (except in pronghorns, whi ...

Parietal Bone
The parietal bones ( ) are two bones in the skull which, when joined at a fibrous joint known as a cranial suture, form the sides and roof of the neurocranium. In humans, each bone is roughly quadrilateral in form, and has two surfaces, four borders, and four angles. It is named from the Latin ''paries'' (''-ietis''), wall. Surfaces External The external surface [Fig. 1] is convex, smooth, and marked near the center by an eminence, the parietal eminence (''tuber parietale''), which indicates the point where ossification commenced. Crossing the middle of the bone in an arched direction are two curved lines, the superior and inferior temporal lines; the former gives attachment to the temporal fascia, and the latter indicates the upper limit of the muscular origin of the temporal muscle. Above these lines the bone is covered by a tough layer of fibrous tissue – the epicranial aponeurosis; below them it forms part of the temporal fossa, and affords attachment to the temporal mu ...

Frontal Bone
In the human skull, the frontal bone or sincipital bone is an unpaired bone which consists of two portions.'' Gray's Anatomy'' (1918) These are the vertically oriented squamous part, and the horizontally oriented orbital part, making up the bony part of the forehead, part of the bony orbital cavity holding the eye, and part of the bony part of the nose respectively. The name comes from the Latin word ''frons'' (meaning "forehead"). Structure The frontal bone is made up of two main parts. These are the squamous part, and the orbital part. The squamous part marks the vertical, flat, and also the biggest part, and the main region of the forehead. The orbital part is the horizontal and second biggest region of the frontal bone. It enters into the formation of the roofs of the orbital and nasal cavities. Sometimes a third part is included as the nasal part of the frontal bone, and sometimes this is included with the squamous part. The nasal part is between the brow ridges, ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

A Latin Dictionary
''A Latin Dictionary'' (or ''Harpers' Latin Dictionary'', often referred to as Lewis and Short or L&S) is a popular English-language lexicographical work of the Latin language, published by Harper and Brothers of New York in 1879 and printed simultaneously in the United Kingdom by Oxford University Press. History The work is usually referred to as ''Lewis and Short'' after the names of its editors, Charlton T. Lewis and Charles Short. It was derived from the 1850 English translation by Ethan Allen Andrews of an earlier Latin–German dictionary, , by the German philologist Wilhelm Freund, in turn based on I. J. G. Scheller’s Latin–German dictionary of 1783. The Andrews translation was partially revised by Freund himself, then by Henry Drisler, and was finally edited by Short and Lewis. The division of labour between the two editors was remarkably unequal. Short, a very thorough but slow worker, produced material for the letters A through C, but B and C were lost by ...

Latin Language
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest. Latin Root (linguistics), roots appear frequently in the technical vocabulary used by fields such as theology, List of Latin and Greek words commonly used in systematic names, the sciences, List of medical roots, suffixes and prefixes, medicine, and List of Latin legal terms ...

A Greek–English Lexicon
''A Greek–English Lexicon'', often referred to as ''Liddell & Scott'' () or ''Liddell–Scott–Jones'' (''LSJ''), is a standard lexicographical work of the Ancient Greek language originally edited by Henry George Liddell, Robert Scott, Henry Stuart Jones, and Roderick McKenzie and published in 1843 by the Oxford University Press. It was most recently revised for its ninth edition of 1940. Abridged versions and a supplement exist. It was initially the basis for the 2021 '' Cambridge Greek Lexicon'', although subsequently that became a complete rewrite from scratch. Liddell and Scott's lexicon (1843–1940) The lexicon was begun in the 19th century, and is now in its ninth (revised) edition, published in 1940. It was based on the earlier by the German lexicographer Franz Passow (first published in 1819, fourth edition 1831), which in turn was based on Johann Gottlob Schneider's . The ''Lexicon'' has served as the basis for all later lexicographical work on the ancient G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
