Equus Sivalensis
''Equus sivalensis'' is an extinct species of large equid native to the northern Indian subcontinent. Remains date from the beginning of the Pleistocene, c. 2.58 million years ago until around 600,000 years ago, during the Middle Pleistocene. It is considered a "stenonine horse", meaning that it is more closely related to zebras and asses than true horses. Based on isotopes and teeth morphology, it is thought to have been a grazer. The later species '' Equus namadicus'' from the same region has sometimes been suggested to be a synonym due to their similar teeth morphology. References * B.J.

Hugh Falconer
Hugh Falconer MD FRS (29 February 1808 – 31 January 1865) was a Scottish geologist, botanist, palaeontologist, and paleoanthropologist. He studied the flora, fauna, and geology of India, Assam, Burma, and most of the Mediterranean islands and was the first to suggest the modern evolutionary theory of punctuated equilibrium. He studied the Siwalik fossil beds, and may also have been the first person to discover a fossil ape. Early life Falconer was the youngest son of David Falconer of Forres , Elginshire. In 1826 Hugh Falconer graduated at the University of Aberdeen, where he studied natural history. Afterward, he studied medicine in the University of Edinburgh, taking the degree of MD in 1829.Arnold, David (2006) ''The Tropics and the Traveling Gaze: India, Landscape, and Science, 1800–1856'' University of Washington Press, Seattlepp. 156–157 During this period he zealously attended the botanical classes of Prof. R. Graham (1786–1845), and those on geology by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proby Cautley
Sir Proby Thomas Cautley, KCB (3 January 1802 – 25 January 1871), was an English engineer and palaeontologist who is best known for having conceived and supervised the construction of the Ganges canal during East India Company rule in India. The canal stretches some 350 miles between its headworks at Haridwar and, after bifurcation near Aligarh, its confluences with the Ganges river mainstem in Kanpur and the Yamuna river in Etawah.Stone (2002) p.18 At the time of completion, it had the greatest discharge of any irrigation canal in the world. Proby Cautley was educated at Charterhouse School (1813–18), followed by the East India Company's Military Seminary at Addiscombe (1818–19). After less than a year, he was commissioned as a second lieutenant and dispatched to India, joining the Bengal Presidency artillery in Calcutta. In 1825, he assisted Captain Robert Smith, the engineer in charge of constructing the Eastern Yamuna canal, also called the Doab canal. He was in ...

Equus (genus)
''Equus'' () is a genus of mammals in the perissodactyl family (biology), family Equidae, which includes wild horse, horses, Asinus, asses, and zebras. Within the Equidae, ''Equus'' is the only recognized Extant taxon, extant genus, comprising seven living species. Like Equidae more broadly, ''Equus'' has numerous extinct species known only from fossils. The genus originated in North America and dispersed into the Old World and South America during the Early and Middle Pleistocene. Equinae, Equines are odd-toed ungulates with slender legs, long heads, relatively long necks, manes (erect in most subspecies), and long tails. All species are herbivorous, and mostly grazers, with simpler digestive systems than Ruminantia, ruminants but able to subsist on lower-quality vegetation. While the domestic horse and donkey (along with their feral horse, feral descendants) exist worldwide, wild equine populations are limited to Africa and Asia. Wild equine social systems are in two forms; a H ... [...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 ...

Middle Pleistocene
The Chibanian, more widely known as the Middle Pleistocene (its previous informal name), is an Age (geology), age in the international geologic timescale or a Stage (stratigraphy), stage in chronostratigraphy, being a division of the Pleistocene Epoch within the ongoing Quaternary Period. The Chibanian name was officially ratified in January 2020. It is currently estimated to span the time between 0.7741 annum, Ma (774,100 years ago) and 0.129 Ma (129,000 years ago), also expressed as 774.1–129 ka. It includes the transition in palaeoanthropology from the Lower Paleolithic, Lower to the Middle Paleolithic over 300 ka. The Chibanian is preceded by the Calabrian (stage), Calabrian and succeeded by the Late Pleistocene. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. Its end roughly coincides with the termination of the Penultimate Glacial Period and the onset of the Last Interglacial period (correspondin ...

Grazing (behaviour)
Grazing is a method of eating, feeding in which a herbivore feeds on low-growing plants such as grasses or other multicellular organisms, such as algae. Many species of animals can be said to be grazers, from large animals such as Hippopotamus, hippopotamuses to small aquatic Snail, snails. Grazing Ethology, behaviour is a type of List of feeding behaviours, feeding strategy within the ecology of a species. Specific grazing strategies include Graminivore, graminivory (eating grasses); coprophagy (producing part-digested pellets which are reingested); pseudoruminant (having a multi-chambered stomach but not chewing the cud); and grazing on plants other than grass, such as on marine algae. Grazing's ecological effects can include redistributing nutrients, keeping grasslands open or favouring a particular species over another. Ecology Many small selective herbivores follow larger grazers which skim off the highest, tough growth of grasses, exposing tender shoots. For terrestrial a ...

Equus Namadicus
''Equus namadicus'' is a prehistoric equid, known from remains dating to the Middle and Late Pleistocene from across the Indian subcontinent The Indian subcontinent is a physiographic region of Asia below the Himalayas which projects into the Indian Ocean between the Bay of Bengal to the east and the Arabian Sea to the west. It is now divided between Bangladesh, India, and Pakista ..., with its last dated records being approximately 29–14,000 years ago. It is considered a "stenonine horse", related to species like the European '' Equus stenonis'', meaning that it is probably more closely related to zebras and asses than true horses. It is relatively large in size. It is very similar to the earlier '' Equus sivalensis,'' also from the Indian subcontinent, from which it only differs in size and in subtle aspects of dental anatomy, and it has sometimes been suggested to be a synonym of it.
