Location North America
In geography, location or place are used to denote a region (point, line, or area) on Earth's surface or elsewhere. The term ''location'' generally implies a higher degree of certainty than ''place'', the latter often indicating an entity with an ambiguous boundary, relying more on human or social attributes of place identity and sense of place than on geometry. Types Locality A suburb, locality, human settlement, settlement, or populated place is likely to have a well-defined name but a boundary that is not well defined varies by context. London, for instance, has a legal boundary, but this is unlikely to completely match with general usage. An area within a town, such as Covent Garden in London, also almost always has some ambiguity as to its extent. In geography, location is considered to be more precise than "place". Relative location A relative location, or situation, is described as a displacement from another site. An example is "3 miles northwest of Seattle". Absolute lo ...

American Camel
''Camelops''Being occasionally called ''Western Camel'' or ''Yesterday's Camel''. is an extinct genus of camels that lived in North and Central America, ranging from Alaska to Guatemala, from the middle Pliocene to the end of the Pleistocene. It is more closely related to the Old World dromedary and bactrian and wild bactrian camels than the New World guanaco, vicuña, alpaca and llama; making it a true camel of the Camelini tribe. Its name is derived from the Ancient Greek (, "camel") and (, "face"), i.e. "camel-face". Taxonomy and evolution The genus ''Camelops'' first appeared during the middle Pliocene (about 4.0–3.2 million years ago (Mya) in southern North America and became extinct at the end of the Pleistocene (around 11,000 years ago). Despite the fact that camels are popularly associated with the deserts of Asia and Africa, the family Camelidae, which comprises camels and llamas, originated in North America during the middle Eocene period, at least 44 Mya.

Cuvieronius
''Cuvieronius'' is an extinct New World genus of gomphothere, named after the French naturalist Georges Cuvier. Alive, specimens typically stood about tall at the shoulder, weighed about and would have superficially resembled a modern elephant with spiral-shaped tusks. Taxonomy The species now known as ''Cuvieronius hyodon'' was among the first fossil animals from the New World to be studied. The first remains of this species were recovered from Ecuador by Alexander von Humboldt, at a location the local population referred to as the "Field of Giants".Mayor, A. (2005). Fossil legends of the first Americans. Princeton University Press. Humboldt recognized that, rather than being bones of giant humans as had been thought by the local population and previous Spanish colonists, they were similar to the giant elephants (''Mastodon'') being described from Ohio. Humboldt sent teeth that he had collected from Mexico, Ecuador, and Chile to French anatomist Georges Cuvier, who classifie ...

Life Restoration Cervalces Scotti
Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from that which does not, and is defined by the capacity for growth, reaction to stimuli, metabolism, energy transformation, and reproduction. Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria. Biology is the science that studies life. The gene is the unit of heredity, whereas the cell is the structural and functional unit of life. There are two kinds of cells, prokaryotic and eukaryotic, both of which consist of cytoplasm enclosed within a membrane and contain many biomolecules such as proteins and nucleic acids. Cells reproduce through a process of cell division, in which the parent cell divides into two or more daughter cells and passes its genes onto a new generation, sometimes producing genetic variation. Organisms, or the individual entities of life, are generally thought to be open systems that maint ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern United States
The Eastern United States, commonly referred to as the American East, Eastern America, or simply the East, is the region of the United States to the east of the Mississippi River. In some cases the term may refer to a smaller area or the East Coast plus Illinois, Wisconsin, Indiana, Mississippi, and their border states. In 2011, the 26 states east of the Mississippi (in addition to Washington, D.C. but not including the small portions of Louisiana and Minnesota east of the river) had an estimated population of 179,948,346 or 58.28% of the total U.S. population of 331,745,358 (excluding Puerto Rico). New England New England is a region of the United States located in the northeastern corner of the country, bounded by the Atlantic Ocean, Canada and the state of New York, consisting of the modern states of Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut. In one of the earliest English settlements in the New World, English Pilgrims from Europe first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stag-moose
''Cervalces scotti'', the elk moose or stag-moose, is an extinct species of large deer that lived in North America during the Late Pleistocene epoch. It had palmate antlers that were more complex than those of a moose and a muzzle more closely resembling that of a typical deer. It is the only known North American member of the genus ''Cervalces''. Description It was as large as the moose, with an elk-like head, long legs, and palmate antlers that were more complex and heavily branching than the moose. ''Cervalces scotti'' reached in length and a weight of . The stag-moose resided in North America during an era with other megafauna such as the woolly mammoth, ground sloth, long horn bison, and saber toothed cat."Cervalces Scotti." Maxilla & Mandible. N.p., n.d. Web. 23 Oct. 2014. . The species became extinct approximately 11,500 years ago, toward the end of the most recent ice age, as part of a mass extinction of large North American mammals.

Castoroides Knight 1
''Castoroides'' (Latin: "beaver" (castor), "like" (oides)), or giant beaver, is an extinct genus of enormous, bear-sized beavers that lived in North America during the Pleistocene. Two species are currently recognized, ''C. dilophidus'' in the Southeastern US and ''C. ohioensis'' in the rest of its range. ''C. leiseyorum'' was previously described from the Irvingtonian of Florida, but is now regarded as an invalid name. All specimens previously described as ''C. leiseyorum'' are considered to belong to ''C. dilophidus''. Description Species of ''Castoroides'' were much larger than modern beavers. Their average length was approximately , and they could grow as large as . The weight of the giant beaver could vary from to . This makes it the largest known rodent in North America during the Pleistocene and the largest known beaver. Recent analyses suggest that they weighed less, closer to , but this is disputable. The hind feet of the giant beaver were much larger than in modern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Capromeryx Minor
''Capromeryx'' (dwarf pronghorn) was a genus of dwarf pronghorns (Antilocapridae) that originated in North America during the Pliocene about 5 million years ago (the exact range of their presence on the landscape is still not known, but the most recent fossils found are dated to 11,000 years ago). The closest living relative and only surviving member of the family is the North American pronghorn (''Antilocapra americana''). Description ''Capromeryx'' were the smallest members of the pronghorn family Antilocapridae. They are recognized by having two upright horns that are conical in shape (wider at the base and tapering toward the top). The United States distribution of this genus includes: Arizona, California, Florida, New Mexico, Texas, and Washington. Fossils have also been found in the Mexican states of: Chihuahua, Sonara, and Baja California. Many ''Capromeryx'' fossils have been found in tar pits, and juveniles are especially common. One such location is the Rancho La Brea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southwestern United States
The Southwestern United States, also known as the American Southwest or simply the Southwest, is a geographic and cultural region of the United States that generally includes Arizona, New Mexico, and adjacent portions of California, Colorado, Nevada, Oklahoma, Texas, and Utah. The largest cities by metropolitan area are Phoenix, Las Vegas, El Paso, Albuquerque, and Tucson. Prior to 1848, in the historical region of Santa Fe de Nuevo México as well as parts of Alta California and Coahuila y Tejas, settlement was almost non-existent outside of Nuevo México's Pueblos and Spanish or Mexican municipalities. Much of the area had been a part of New Spain and Mexico until the United States acquired the area through the Treaty of Guadalupe Hidalgo in 1848 and the smaller Gadsden Purchase in 1854. While the region's boundaries are not officially defined, there have been attempts to do so. One such definition is from the Mojave Desert in California in the west (117° west longitude) t ...
