Mastodon Mobile Web Screenshot
A mastodon, from Ancient Greek μαστός (''mastós''), meaning "breast", and ὀδούς (''odoús'') "tooth", is a member of the genus ''Mammut'' (German for 'mammoth'), which was endemic to North America and lived from the late Miocene to the early Holocene. Mastodons belong to the order Proboscidea, the same order as elephants and mammoths (which belong to the family Elephantidae). ''Mammut'' is the type genus of the extinct family Mammutidae, which diverged from the ancestors of modern elephants at least 27–25 million years ago, during the Oligocene. Like other members of Mammutidae, the molar (tooth), molar teeth of mastodons have zygodont morphology (where parallel pairs of cusp (anatomy), cusps are merged into sharp ridges), which strongly differ from those of elephantids. In comparison to its likely ancestor ''Zygolophodon'', ''Mammut'' is characterized by particularly long and upward curving upper tusks, reduced or absent tusks on the lower jaw, as well as th ...

Miocene
The Miocene ( ) is the first epoch (geology), 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 followed the Oligocene and preceded 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 distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Harlan
Richard Harlan (September 19, 1796 – September 30, 1843) was an American paleontologist, anatomist, and physician. He was the first American to devote significant time and attention to vertebrate paleontology and was one of the most important contributors to the field in the early nineteenth century. His work was noted for its focus on objective descriptions, taxonomy and nomenclature. He was the first American to routinely apply binomial Linnaean names to vertebrate and invertebrate fossils. Prior to the time of Harlan, it was common practice to publish only a genus name for a fossil animal that was new to science. Biography Harlan was born in Philadelphia on September 19, 1796, to Joshua Harlan, a wealthy Quaker merchant, and his wife Sarah Hinchman Harlan, one of their ten children. He was three years older than his brother Josiah Harlan, who would become the first American to visit Afghanistan. Harlan graduated in medicine from the University of Pennsylvania in 1818 afte ...

Elephant
Elephants are the largest living land animals. Three living species are currently recognised: the African bush elephant ('' Loxodonta africana''), the African forest elephant (''L. cyclotis''), and the Asian elephant ('' Elephas maximus''). They are the only surviving members of the family Elephantidae and the order Proboscidea; extinct relatives include mammoths and mastodons. Distinctive features of elephants include a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive grey skin. The trunk is prehensile, bringing food and water to the mouth and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a constant body temperature as well as in communication. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears and convex or level backs. Elephants are scatter ...

Proboscidea
Proboscidea (; , ) is 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. Three living species of elephant are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. Extinct members of Proboscidea include the deinotheres, mastodons, gomphotheres and stegodonts. The family Elephantidae also contains several extinct groups, including mammoths and '' Palaeoloxodon''. Proboscideans include some of the largest known land mammals, with the elephant '' Palaeoloxodon namadicus'' and mastodon ''"Mammut" borsoni'' suggested to have body masses surpassing , rivalling or exceeding paraceratheres (the otherwise largest known land mammals) in size. The largest extant proboscidean is the African bush elephant, with a world record of size of at the shoulder and . In addition to thei ...

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auguste Pomel
Nicolas Auguste Pomel (20 September 1821 – 2 August 1898) was a French geologist, paleontologist and botanist. He worked as a mines engineer in Algeria and became a specialist in north African vertebrate fossils. He was Senator of Algeria for Oran from 1876 to 1882. Life Nicolas-Auguste Pomel was born in Issoire, Puy-de-Dôme, on 20 September 1821. He studied at the Lycée de Clermont and earned his '' licence ès sciences''. He was conscripted into the army when he was prepared to enter the École des mines. He became a civil engineer after being released. After the coup d'état of 2 December 1851 his Republican beliefs earned him deportation. He became a ''Garde des mines'' in Oran in 1866, and was promoted to the 1st class in 1872. From 1876 to 1882 he was member of the Senate (Oran division). In 1882 he was tasked with geological mapping of Algeria. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Gaylord Simpson
George Gaylord Simpson (June 16, 1902 – October 6, 1984) was an American paleontologist. Simpson was perhaps the most influential paleontologist of the twentieth century, and a major participant in the modern synthesis, contributing '' Tempo and Mode in Evolution'' (1944), ''The Meaning of Evolution'' (1949) and ''The Major Features of Evolution'' (1953). He was an expert on extinct mammals and their intercontinental migrations. Simpson was extraordinarily knowledgeable about Mesozoic fossil mammals and fossil mammals of North and South America. He anticipated such concepts as punctuated equilibrium (in ''Tempo and Mode'') and dispelled the myth that the evolution of the horse was a linear process culminating in the modern '' Equus caballus''. He coined the word '' hypodigm'' in 1940, and published extensively on the taxonomy of fossil and extant mammals. Simpson was influentially, and incorrectly, opposed to Alfred Wegener's theory of continental drift, but accepted the th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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.
