Preceramic Period In Belize
The Preceramic Period of Belizean and Mesoamerican history began with the arrival of the first Palaeoindians during 20000 BC11000 BC, and ended with the Mayan development of ceramics during 2000 BC900 BC. Geography During the pre-Columbian era, Belize formed part of Mesoamerica. Traditionally, the first-order subdivisions of the latter follow cultural or political boundaries of Preclassic, Classic, or Postclassic civilisations, eg Mayans and Aztecs. The Mayan region of Mesoamerica is one such. It, in turn, is further subdivided physiographically into at least three regions, ie the Lowlands, the Highlands, and the Pacific. Belize lay within the first of these regions, usually termed the Mayan Lowlands. Climate During the Younger Dryas stage, as the Pleistocene progressed to the Holocene epoch, Belize's climate became increasingly warmer and wetter, its expansive savannah fields increasingly covered by dense tropical broadleaf forests, and its low-lying coast submerged by a ...

Preclassic Period In Belize
The Preclassic or Formative Period of Belizean, Mayan, and Mesoamerican history began with the Mayan development of ceramics during 2000 BC900 BC, and ended with the advent of Mayan monumental inscriptions in 250 AD. Geography During the pre-Columbian era, Belize formed part of Mesoamerica. Traditionally, the first-order subdivisions of the latter follow cultural or political boundaries of Preclassic, Classic, or Postclassic civilisations, eg Mayans and Aztecs. The ''Mayan region'' of Mesoamerica is one such. It, in turn, is further subdivided physiographically into at least three regions, ie the ''Mayan Lowlands'', ''Highlands'', and ''Pacific''. The first of these second-order subdivisions, which fully encompassed Belize, is still further subdivided into northern, central, and southern portions, called the ''Northern'', ''Central'', and ''Southern Lowlands''. Belizean territory north of Indian Creek ie Nim Li Punit is often included within the Central Lowlands, fully enc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Spondias Mombin
''Spondias mombin'', also known as yellow mombin or hog plum is a species of tree and flowering plant in the family Anacardiaceae. It is native to the tropical Americas, including the West Indies. The tree was introduced by the Portuguese in South Asia in the beginning of the 17th century. It has been naturalized in parts of Africa, India, Nepal, Bangladesh, Sri Lanka, The Bahamas, Indonesia, and other Caribbean islands. It is rarely cultivated except in parts of the Brazilian Northeast. The mature fruit has a leathery skin and a thin layer of pulp. The seed has an oil content of 31.5%. Description ''Spondias mombin'' is a small deciduous tree up to high and in girth, and is moderately buttressed. Its bark is thick, corky, and deeply fissured. When slashed, it is pale pink, darkening rapidly. Branches are low and branchlets are glabrous. The leaves are pinnate, with 5-8 leaflets opposite pairs with a terminal leaflet, , oblong or oblong lanceolate, broadly acuminate ...

Common Agouti
The agouti (, ) or common agouti is any of several rodent species of the genus ''Dasyprocta''. They are native to Middle America (Americas), Middle America, northern and central South America, and the southern Lesser Antilles. Some species have also been Introduced species, introduced elsewhere in the West Indies. They are related to guinea pigs and look quite similar, but they are larger and have longer legs. The species vary considerably in colour, being brown, reddish, dull orange, greyish, or blackish, but typically with lighter underparts. Their bodies are covered with coarse hair, which is raised when alarmed. They weigh and are in length, with short, hairless tails. The related pacas were placed by some authorities in a genus called ''Agouti'', though ''Cuniculus'' has priority and is the correct term. In West Africa (especially Ivory Coast), the name "agouti" designates the greater cane rat which, while an agricultural pest, is often sought as a bushmeat delicacy. T ...

Peccary
A peccary (also javelina or skunk pig) is a medium-sized, pig-like hoofed mammal of the family Tayassuidae (New World pigs). They are found throughout Central and South America, Trinidad in the Caribbean, and in the southwestern area of North America. They usually measure between in length, and a full-grown adult usually weighs about . They represent the closest relatives of the family Suidae, which contains pigs and relatives. Together Tayassuidae and Suidae are grouped in the Suina within the Artiodactyla (even toed ungulates). Peccaries are social creatures that live in herds. They eat roots, grubs, and a variety of foods. They can identify each other by their strong odors. A group of peccaries that travel and live together is called a "squadron". A squadron of peccaries averages between six and nine members. Peccaries first appeared in North America during the Miocene, and migrated into South America during the Pliocene-Pleistocene as part of the Great American Interchange ...

Rock Shelter
A rock shelter (also rockhouse, crepuscular cave, bluff shelter, or abri) is a shallow cave-like opening at the base of a bluff or cliff. In contrast to solutional caves (karst), which are often many miles long, rock shelters are almost always modest in size and extent. Formation Rock shelters form because a rock stratum such as sandstone that is resistant to erosion and weathering has formed a cliff or bluff, but a softer stratum, more subject to erosion and weathering, lies just below the resistant stratum, and thus undercuts the cliff. In arid areas, wind erosion (Aeolian erosion) can be an important factor in rockhouse formation. In most humid areas, the most important factor in rockhouse formation is frost spalling, where the softer, more porous rock underneath is pushed off, tiny pieces at a time, by frost expansion from water frozen in the pores. Erosion from moving water is seldom a significant factor. Many rock shelters are found under waterfalls. File:Rock shelt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calc ...

Hand Axe
A hand axe (or handaxe or Acheulean hand axe) is a prehistoric stone tool with two faces that is the longest-used tool in human history, yet there is no academic consensus on what they were used for. It is made from stone, usually flint or chert that has been "reduced" and shaped from a larger piece by knapping, or hitting against another stone. They are characteristic of the lower Acheulean and middle Palaeolithic (Mousterian) periods, roughly 1.6 million years ago to about 100,000 years ago, and used by ''Homo erectus'' and other early humans, but rarely by ''Homo sapiens''. Their technical name (biface) comes from the fact that the archetypical model is a generally bifacial (with two wide sides or faces) and almond-shaped (amygdaloidal) lithic flake. Hand axes tend to be symmetrical along their longitudinal axis and formed by pressure or percussion. The most common hand axes have a pointed end and rounded base, which gives them their characteristic almond shape, and both f ...

Cueva Fell
Cueva Fell is a natural cave and archaeological site in southern Patagonia. Cueva Fell is in proximity to the Pali Aike Crater, another significant archaeological site. Cueva Fell combined with the nearby Pali Aike site have been submitted to UNESCO as a possible World Heritage Site. Site discovery Fell's Cave was discovered by Junius Bird. It came to his attention because arrow points and flakes were found on the surface. The cave was originally called the Río Chico shelter, but was later renamed by Bird to Fell's Cave in honor of the Fell family who owned the Estancia Brazo Norte, the North Arm Station, where the cave is located. Excavation of the site began in 1936. Site formation Fell's Cave is located in the Río Chico canyon, Chile, near the Straits of Magellan and the Argentine border. This area is known as the ''Southern Patagonian Basalt Plateaus''.Markgraf, in Bird, 1988, p.196 Situated on the southeast side of what was once a river bank, it is more accurately ...
