Mastodons
A mastodon ( 'breast' + 'tooth') is any proboscidean belonging to the extinct genus ''Mammut'' (family Mammutidae). Mastodons inhabited North and Central America during the late Miocene or late Pliocene up to their extinction at the end of the Pleistocene 10,000 to 11,000 years ago. They lived in herds and were predominantly forest-dwelling animals. They generally had a browsing diet, distinct from that of the contemporary Columbian mammoth, which tended towards grazing. ''M. americanum'', the American mastodon, and ''M. pacificus'', the Pacific mastodon, are the youngest and best-known species of the genus. Mastodons disappeared from North America as part of a mass extinction of most of the Pleistocene megafauna, widely believed to have been caused by a combination of climate changes at the end of the Pleistocene and overexploitation by Paleo-Indians. History A Dutch tenant farmer found the first recorded remnant of ''Mammut'', a tooth some in weight, in the village of ...

Mammutidae
Mammutidae is an extinct family of proboscideans that appeared during the Oligocene epoch and survived until the start of the Holocene. The family was first described in 1922, classifying fossil specimens of the type genus ''Mammut'' (mastodons), and has since been placed in various arrangements of the order. The name "mastodon" derives from Greek, "nipple" and "tooth", as with the genus, referring to a characteristic that distinguishes them from allied families. The genus ''Zygolophodon'' has also been assigned to this family. Mammutids ranged very widely, with fossils found in North America, Africa, and throughout Eurasia. Discoveries Since the 18th century several fossils have been found in different regions of Venezuela; the first one of these fossils was reviewed by Alexander von Humboldt. In August 2008, miners in Romania unearthed the skeleton of a 2.5-million-year-old mastodon, believed to be one of the best preserved in Europe.

Claverack, New York
Claverack is a town in Columbia County, New York, United States. The population was 6,021 at the 2010 census. The town name is a corruption for the Dutch word “Klaverakker” for "Clover Fields" or "Clover Reach". In 1705, the first discovery of a mastodon tooth occurred here. The town is centrally located in Columbia County, east of the city of Hudson. History Claverack was originally approximately in area and was known as the Lower Manor of Rensselaer. The town was formed in 1778 from the older District of Claverack. In 1782, the town lost some of its land to the new town of Hillsdale. The town was reduced again in 1785 to form the city of Hudson. In 1779 Washington Seminary was founded in the town by the local Dutch Reformed pastor. Prominent former students at the school include U.S. President Martin Van Buren. In the nineteenth century the school was renamed Claverack College, and it closed in 1902. The many 18th century homes in the area include the 1786 William Hen ...

Browsing (herbivory)
Browsing is a type of herbivory in which a herbivore (or, more narrowly defined, a folivore) feeds on leaves, soft shoots, or fruits of high-growing, generally woody plants such as shrubs. This is contrasted with Grazing (behaviour), grazing, usually associated with animals feeding on grass or other lower vegetations. Alternatively, grazers are animals eating mainly grass, and browsers are animals eating mainly non-grasses, which include both woody and herbaceous Dicotyledon, dicots. In either case, an example of this dichotomy are goats (which are primarily browsers) and Domestic sheep, sheep (which are primarily grazers). Browse The plant material eaten is known as ''browse'' and is in nature taken directly from the plant, though owners of livestock such as goats and deer may cut twigs or branches for feeding to their stock. In temperate regions, owners take browse before leaf fall, then dry and store it as a winter feed supplement. In time of drought, herdsmen may cut branche ...

Slavery In The United States
The legal institution of human chattel slavery, comprising the enslavement primarily of Africans and African Americans, was prevalent in the United States of America from its founding in 1776 until 1865, predominantly in the South. Slavery was established throughout European colonization in the Americas. From 1526, during early colonial days, it was practiced in what became Britain's colonies, including the Thirteen Colonies that formed the United States. Under the law, an enslaved person was treated as property that could be bought, sold, or given away. Slavery lasted in about half of U.S. states until abolition. In the decades after the end of Reconstruction, many of slavery's economic and social functions were continued through segregation, sharecropping, and convict leasing. By the time of the American Revolution (1775–1783), the status of enslaved people had been institutionalized as a racial caste associated with African ancestry. During and immediately ...

Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-ga ...

Big Bone Lick State Park
Big Bone Lick State Park is located at Big Bone in Boone County, Kentucky. The name of the park comes from the Pleistocene megafauna fossils found there. Mammoths are believed to have been drawn to this location by a salt lick deposited around the sulfur springs. Other animals including forms of bison, caribou, deer, elk, horse, mastodon, moose, musk ox, peccary, ground sloths, wolves, black bears, stag moose, saber-toothed cats, and possibly tapir also grazed the vegetation and salty earth around the springs that the animals relied on for their diet. One mastodon bone was unearthed here with a noticeable cut mark on it, implying that the Clovis people lived in the area thousands of years ago. The area near the springs was very soft and marshy causing many animals to become stuck with no way to escape. It bills itself as "the birthplace of American paleontology", a term which dates from the 1807 expedition by William Clark undertaken at the direction of President Thomas J ...

C W Peale - The Exhumation Of The Mastadon
C, or c, is the third letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''cee'' (pronounced ), plural ''cees''. History "C" comes from the same letter as "G". The Semites named it gimel. The sign is possibly adapted from an Egyptian hieroglyph for a staff sling, which may have been the meaning of the name ''gimel''. Another possibility is that it depicted a camel, the Semitic name for which was ''gamal''. Barry B. Powell, a specialist in the history of writing, states "It is hard to imagine how gimel = "camel" can be derived from the picture of a camel (it may show his hump, or his head and neck!)". In the Etruscan language, plosive consonants had no contrastive voicing, so the Greek ' Γ' (Gamma) was adopted into the Etruscan alphabet to represent . Already in the Western Greek alphabet, Gamma first took a '' form in Early Etruscan, then '' in Classical Etru ...

Overexploitation
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is also used and defined some ...
