Arsinotherium
''Arsinoitherium'' is an extinct genus of paenungulate mammals belonging to the extinct order Embrithopoda. It is related to elephants, sirenians, hyraxes and the extinct desmostylians. Arsinoitheres were superficially rhinoceros-like herbivores that lived during the Late Eocene and the Early Oligocene of North Africa from 36 to 30 million years ago, in areas of tropical rainforest and at the margin of mangrove swamps. A species described in 2004, ''A. giganteum'', lived in Ethiopia about 27 million years ago. Taxonomy The best-known (and first-described) species is ''A. zitteli''. Another species, ''A. giganteum'', was discovered in the Ethiopian highlands of Chilga in 2003. The fossil teeth, far larger than those of ''A. zitteli'', date to around 28–27 million years ago. While the Fayum Oasis is the only site where complete skeletons of ''Arsinoitherium'' fossils were recovered, arsinoitheriids have been found in southeastern Europe, including ''Crivadiatherium'' ...

Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). 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'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. 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 isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...

Chilga
Chilga (Amharic: ጭልጋ ''č̣ilgā'') also Chelga, Ch'ilga is a woreda in Amhara Region, Ethiopia. It is named after its chief town Chilga (also known as Ayikel), an important stopping point on the historic Gondar-Sudan trade route. Part of the Maekelawi Gondar Zone, Chilga is bordered on the south by Takusa, on the west by Metemma, on the north by Tach Armachiho, on the northeast by Lay Armachiho, and on the east by Dembiya. Other towns in Chilga include Seraba and Wohni. Overview Elevations in this woreda range between 1000 and 1500 meters above sea level. Rivers include the Atbarah. A survey of the land in this woreda shows that 21.7% is arable or cultivable, 1.9% pasture, 22.3% forest or shrubland, and the remaining 54.1% is considered degraded or other. This survey covered more of the woreda than the sample enumeration performed by the Central Statistical Agency (CSA) in 2001. One notable landmark in this woreda is the archeological site at Chilga Kernet, which was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bovid
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, and caprines. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and pelage colouration. Excepting some domesticated forms, all male bovids have two or more horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to 32 teeth. Most bovids are diurnal. Social activity and feeding usually peak during dawn and dusk. Bovids typically rest before dawn, during midday, an ...

Karl Alfred Ritter Von Zittel
Karl Alfred Ritter von Zittel (25 September 1839 – 5 January 1904) was a German palaeontologist best known for his ''Handbuch der Palaeontologie'' (1876–1880). Biography Karl Alfred von Zittel was born in Bahlingen in the Grand Duchy of Baden. His father, Karl was a leading liberal cleric in Baden. He was educated at the University of Heidelberg, the University of Paris and the University of Vienna. For a short period he served on the Geological Survey of Austria, and as assistant in the mineralogical museum at Vienna. In 1863, he became teacher of geology and mineralogy in the polytechnic at Karlsruhe, and three years later he succeeded Albert Oppel as professor of palaeontology in the University of Munich, with the charge of the state collection of fossils. In 1880, he was appointed to the geological professorship, and eventually to the directorship of the natural history museum of Munich. His earlier work comprised a monograph on the ''Cretaceous bivalve mollusca of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Faiyum Oasis
The Faiyum Oasis ( ar, واحة الفيوم ''Waḥet El Fayyum'') is a depression or basin in the desert immediately to the west of the Nile, or just 62 miles south of Cairo in Egypt. The extent of the basin area is estimated at between 1,270 km2 (490 mi2) and 1,700 km2 (656 mi2). The basin floor comprises fields watered by a channel of the Nile, the Bahr Yussef, as it drains into a desert hollow to the west of the Nile Valley. The Bahr Yussef veers west through a narrow neck of land north of Ihnasya, between the archaeological sites of El Lahun and Gurob near Hawara; it then branches out, providing rich agricultural land in the Faiyum basin, draining into the large saltwater Lake Moeris (Birket Qarun). In prehistory it was a freshwater lake, but is today a saltwater lake. It is a source for tilapia and other fish for the local area. Differing from typical oases, whose fertility depends on water obtained from springs, the cultivated land in the Faiyum is ...

Arsinoe I
Arsinoe I ( el, Αρσινόη Α’, 305 BC – after c. 248 BC), Footnote 10 was queen of Egypt by marriage to Ptolemy II Philadelphus. Life Arsinoe was the second daughter and youngest child born to King Lysimachus and Nicaea of Macedon. Her older siblings were Agathocles and Eurydice. Her ancestors were powerful - her paternal grandfather was Agathocles of Pella, a nobleman contemporary to King Philip II of Macedon. Her maternal grandfather was the Regent Antipater. Arsinoe shared a name with her grandmother, though it is unknown whether it was the mother of Lysimachus or of Nicaea as both women remain unnamed in ancient sources. Little is known of her life prior to her marriage. Queen Between 289/88 and 281 BC, Arsinoe married her distant maternal cousin, Ptolemy II Philadelphus, pharaoh of the Ptolemaic Kingdom. The marriage was part of Ptolemy's alliance with her father against Seleucus I Nicator. Through her marriage, she became queen of the Ptolemaic kingdom. Toge ...

Pharaoh
Pharaoh (, ; Egyptian: ''pr ꜥꜣ''; cop, , Pǝrro; Biblical Hebrew: ''Parʿō'') is the vernacular term often used by modern authors for the kings of ancient Egypt who ruled as monarchs from the First Dynasty (c. 3150 BC) until the annexation of Egypt by the Roman Empire in 30 BC. However, regardless of gender, "king" was the term used most frequently by the ancient Egyptians for their monarchs through the middle of the Eighteenth Dynasty during the New Kingdom. The term "pharaoh" was not used contemporaneously for a ruler until a possible reference to Merneptah, c. 1210 BC during the Nineteenth Dynasty, nor consistently used until the decline and instability that began with the Twenty-Fifth Dynasty. In the early dynasties, ancient Egyptian kings had as many as three titles: the Horus, the Sedge and Bee ( ''nswt-bjtj''), and the Two Ladies or Nebty ( ''nbtj'') name. The Golden Horus and the nomen and prenomen titles were added later. In Egyptian society, religio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus (biology)
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...
