El Abra
El Abra is the name given to an extensive archeological site, located in the valley of the same name. El Abra is situated in the east of the municipality Zipaquirá extending to the westernmost part of Tocancipá in the department of Cundinamarca, Colombia. The several hundred metres long series of rock shelters is in the north of the Bogotá savanna on the Altiplano Cundiboyacense, Eastern Ranges of the Colombian Andes at an altitude of . The rock shelter and cave system is one of the first evidences of human settlement in the Americas, dated at 12,400 ± 160 years BP. The site was used by the hunter-gatherers of the Late Pleistocene epoch. Etymology The name El Abra is taken from a large hacienda of that name at the foot of the western portion of the rock formation. The eastern side of the outcropping sandstones is accessible. Climbing activities at these ''Rocas de Sevilla'' are organised. Stratigraphy The first research in the place was conducted in 1967, and the str ...

Petroglyph
A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs, estimated to be 20,000 years old are classified as protected monuments and have been added to the tentative list of UNESCO's World Heritage Sites. Petroglyphs are found worldwide, and are often associated with prehistoric peoples. The word comes from the Greek prefix , from meaning " stone", and meaning "carve", and was originally coined in French as . In scholarly texts, a ''petroglyph'' is a rock engraving, whereas a '' petrograph'' (or ''pictograph'') is a rock painting. In common usage, the words are sometimes used interchangeably. Both types of image belong to the wider and more general category of rock art or parietal art. Petroforms, or patterns and shapes made by man ...

Human Settlement
In geography, statistics and archaeology, a settlement, locality or populated place is a community of people living in a particular location, place. The complexity of a settlement can range from a minuscule number of Dwelling, dwellings grouped together to the largest of cities with surrounding Urban area, urbanized areas. Settlements include Homestead_(building), homesteads, hamlet (place), hamlets, villages, towns and city, cities. A settlement may have known historical properties such as the date or era in which it was first settled or first settled by particular people. A number of factors like war, erosion, and the fall of great empires can result in the formation of abandoned settlements which provides relics for archaeological studies. The Human settling, process of settlement involves human migration. In the field of geospatial predictive modeling, settlements are "a city, town, village or other agglomeration of buildings where people live and work". A settlement co ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, 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 Atmosphere of Earth, 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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern charcoal briquettes used for outdoor cooking may contain many other additives, e.g. coal. The early history of wood charcoal production spans ancient times, rooted in the abundance of wood in various regions. The process typically involves stacking wood billets to form a conical pile, allowing air to enter through openings at the bottom, and igniting the pile gradually. Charcoal burners, skilled professionals tasked with managing the delicate operation, often lived in isolation to tend their wood piles . Throughout histo ...

Bone
A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility. Bones come in a variety of shapes and sizes and have complex internal and external structures. They are lightweight yet strong and hard and serve multiple functions. Bone tissue (osseous tissue), which is also called bone in the uncountable sense of that word, is hard tissue, a type of specialised connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells. Osteoblasts and osteocytes are involved in the formation and mineralisation of bone; osteoclasts are involved in the resorption of bone tissue. Modified (flattened) osteoblasts become the lining cells that form a protective layer on the bone surface. The mine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithic Technology
In archaeology, lithic technology includes a broad array of techniques used to produce usable tools from various types of stone. The earliest stone tools to date have been found at the site of Lomekwi 3 (LOM3) in Kenya and they have been dated to around 3.3 million years ago. The archaeological record of lithic technology is divided into three major time periods: the Paleolithic (Old Stone Age), Mesolithic (Middle Stone Age), and Neolithic (New Stone Age). Not all cultures in all parts of the world exhibit the same pattern of lithic technological development, and stone tool technology continues to be used to this day, but these three time periods represent the span of the archaeological record when lithic technology was paramount. By analysing modern stone tool usage within an ethnoarchaeological context, insight into the breadth of factors influencing lithic technologies in general may be studied. See: Stone tool. For example, for the Gamo of Southern Ethiopia, political, envir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hacienda
A ''hacienda'' ( or ; or ) is an estate (or '' finca''), similar to a Roman '' latifundium'', in Spain and the former Spanish Empire. With origins in Andalusia, ''haciendas'' were variously plantations (perhaps including animals or orchards), mines or factories, with many ''haciendas'' combining these activities. The word is derived from Spanish ''hacer'' (to make, from Latin ''facere'') and ''haciendo'' (making), referring to productive business enterprises. The term ''hacienda'' is imprecise, but usually refers to landed estates of significant size, while smaller holdings were termed ''estancias'' or ''ranchos''. All colonial ''haciendas'' were owned almost exclusively by Spaniards and criollos, or rarely by mixed-race individuals. In Argentina, the term ''estancia'' is used for large estates that in Mexico would be termed ''haciendas''. In recent decades, the term has been used in the United States for an architectural style associated with the traditional estate manor ...

Late Pleistocene
The Late Pleistocene is an unofficial Age (geology), age in the international geologic timescale in chronostratigraphy, also known as the Upper Pleistocene from a Stratigraphy, stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between 129,000 and c. 11,700 years ago. The late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (commonly known as the Middle Pleistocene). The beginning of the Late Pleistocene is the transition between the end of the Penultimate Glacial Period and the beginning of the Last Interglacial around 130,000 years ago (corresponding with the beginning of Marine Isotope Stage 5). The Late Pleistocene ends with the termination of the Younger Dryas, some 10th millennium BC, 11,700 years ago when the Holocene Epoch began. The term Upper Pleistocene is currently in use as a p ...
