Paratetralophodon
Paratetralophodon is an extinct genus of proboscidean from late Neogene deposits in India and China. Although traditionally classified in the family Gomphotheriidae, recent studies find it to be more closely related to modern elephants. ''Paratetralophodon hasnotensis'', found in the Siwalik Hills of northern India North India is a loosely defined region consisting of the northern part of India. The dominant geographical features of North India are the Indo-Gangetic Plain and the Himalayas, which demarcate the region from the Tibetan Plateau and Central ..., is the only unequivocal species in the genus, but the Far Eastern form ''"Tetralophodon" exoletus'' is tentatively considered referable to this genus based on similarities with ''P. hasnotensis'', while specimens from Lantian, China, appear to represent an unnamed species of ''Paratetralophodon''.Shi-Qi Wang; Haruo Saegusa; Jaroon Duangkrayom; Wen He; Shan-Qin Chen (2017).

Proboscidea
The Proboscidea (; , ) are a taxonomic order of afrotherian mammals containing one living family (Elephantidae) and several extinct families. First described by J. Illiger in 1811, it encompasses the elephants and their close relatives. From the mid-Miocene onwards, most proboscideans were very large. The largest land mammal of all time may have been a proboscidean; ''Palaeoloxodon namadicus'' was up to at the shoulder and may have weighed up to , almost double the weight of some sauropods like ''Diplodocus carnegii''. The largest extant proboscidean is the African bush elephant, with a record of size of at the shoulder and . In addition to their enormous size, later proboscideans are distinguished by tusks and long, muscular trunks, which were less developed or absent in early proboscideans. Three species of elephant are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. Elephantidae is the only surviving family of the or ...

Elephantoidea
Elephantoidea is a taxonomic group that contains the elephants as well as their closest extinct relatives. The following cladogram shows the relationships among elephantoids, based on hyoid The hyoid bone (lingual bone or tongue-bone) () is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage. At rest, it lies between the base of the mandible and the third cervical vertebra. ... characteristics: References Taxa named by John Edward Gray {{afrotheria-stub ...

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.

Neogene
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868). During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans (''Homo habilis'') appeared in Africa near the end of the period. Some continental movements took place, the most significant event being the connection of North and South America at the Isthmus of Panama, late in the Pliocene. This cut off the warm ocean currents from the Pacific to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeheskel Shoshani
Jeheskel "Hezy" Shoshani (January 23, 1943 – May 21, 2008) was an evolutionary biologist who studied elephants and their relatives for over 35 years. Life and work Early life and career Shoshani was born in what is now Tel Aviv, Israel, but he held dual citizenship in the United States. His interest in elephants began in his youth after he read a Hebrew copy of Willis Lindquist's ''Burma Boy'', which told the story of the relationship between a boy and an elephant. He began his career as a zookeeper at the Tel Aviv Zoo and became the head zookeeper in 1966. He went on to research elephants in Sri Lanka and Kenya before moving to Detroit, Michigan in 1968 and becoming an undergraduate professor at Wayne State University around 1973. Shoshani founded the Elephant Interest Group (later known as the Elephant Research Foundation) in June 1977, and was the sole editor of its official journal, ''Elephant'' (formerly ''Elephant Newsletter''), for most of its run. He also establish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern India
North India is a loosely defined region consisting of the northern part of India. The dominant geographical features of North India are the Indo-Gangetic Plain and the Himalayas, which demarcate the region from the Tibetan Plateau and Central Asia. The term North India has varying definitions. The Ministry of Home Affairs in its Northern Zonal Council Administrative division included the states of Haryana, Himachal Pradesh, Punjab and Rajasthan and Union Territories of Chandigarh, Delhi, Jammu and Kashmir and Ladakh. The Ministry of Culture in its ''North Culture Zone'' includes the state of Uttarakhand but excludes Delhi whereas the Geological Survey of India includes Uttar Pradesh and Delhi but excludes Rajasthan and Chandigarh. Other states sometimes included are Bihar, Gujarat, Jharkhand, Madhya Pradesh and West Bengal. North India has been the historical centre of the Mughal Empire, the Delhi Sultanate and the British Indian Empire. It has a diverse culture, and includ ...

Prehistoric Placental Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene Proboscideans
The Miocene ( ) is the first 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 is preceded by the Oligocene and is followed by 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 a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
