Pulltrouser Swamp
Pulltrouser Swamp is a wetland area located in northern Belize, between the New River (Belize) and Hondo River (Belize). This area contains numerous archaeological sites belonging to the Maya civilization, the most studied features of which are the raised field structures. Three of these sites, called Raised-Field Site I, Raised-Field Site 2, and Raised-Field site 3, were excavated by archaeologists B.L. Turner and Peter D. Harrison.Turner, B.L. and Peter D. Harrison, 1983. ''Pulltrouser Swamp: ancient Maya habitat, agriculture, and settlement in northern Belize''. Austin: University of Texas Press. Settlements Located north of Orange Walk in Belize is a Y-shaped settlement that makes up a series of complex elongated depressions. In Pulltrouser there were three different immediate settlements that surrounded the swamp equalling 8.5 km. In these settlements the key to organization was the utilization of hillsides and slopes for the raised fields. The people of Pulltrouser ...

Tree Laye
In botany, a tree is a perennial plant with an elongated Plant stem, stem, or trunk (botany), trunk, usually supporting Branch, branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only Bark (botany), woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller Arecaceae, palms, Cyatheales, tree ferns, Musa (genus), bananas, and bamboos. Trees are not a Monophyletic group, monophyletic taxonomic group but consist of a wide variety of plant species that Convergent evolution, have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colha, Belize
Colha, Belize is a Maya archaeological site located in northern portion of the country, about 52 km. north of Belize City, near the town of Orange Walk. The site is one of the earliest in the Maya region and remains important to the archaeological record of the Maya culture well into the Postclassic Period. According to Palma Buttles, “Archaeological evidence from Colha allows for the interpretation occupation from the Early Preceramic (3400-1900B.C.) to Middle Postclassic (A.D. 1150-1300) with population peaks occurring in the Late Preclassic (400B.C.- A.D. 100) and again in the Late Classic ( A.D. 600-850)”.Buttles, Palma J. 2002. Material and Meaning: A Contextual Examination of Select Portable Material Culture from Colha, Belize. Dissertation for University of Texas at Austin. These peaks in population are directly related to the presence of stone tool workshops at the site. Colha's proximity to an important source of high quality chert that is found in the Cenozoic ...

Mesoamerican Chronology
Mesoamerican chronology divides the history of pre-Columbian, prehispanic Mesoamerica into several periods: the Paleo-Indian (first human habitation until 3500 BCE); the Archaic (before 2600 BCE), the Preclassic or Formative (2500 BCE – 250 CE), the Classic (250–900 CE), and the Postclassic (); as well as the post European contact Colonial Period (1521–1821), and Postcolonial, or the period after independence from Spain (1821–present). The periodisation of Mesoamerica by researchers is based on archaeological, ethnohistorical, and modern cultural anthropology research dating to the early twentieth century. Archaeologists, ethnohistorians, historians, and cultural anthropologists continue to work to develop cultural histories of the region. Overview Paleo-Indian period 18000–8000 BCE The Paleo-Indian (less frequently, ''Lithic stage, Lithic'') period or era is that which spans from the first signs of human presence in the region, which ...

Stone Tool
Stone tools have been used throughout human history but are most closely associated with prehistoric cultures and in particular those of the Stone Age. Stone tools may be made of either ground stone or knapped stone, the latter fashioned by a craftsman called a flintknapper. Stone has been used to make a wide variety of tools throughout history, including arrowheads, spearheads, hand axes, and querns. Knapped stone tools are nearly ubiquitous in pre-metal-using societies because they are easily manufactured, the tool stone raw material is usually plentiful, and they are easy to transport and sharpen. The study of stone tools is a cornerstone of prehistoric archaeology because they are essentially indestructible and therefore a ubiquitous component of the archaeological record. Ethnoarchaeology is used to further the understanding and cultural implications of stone tool use and manufacture. Knapped stone tools are made from cryptocrystalline materials such as chert, f ...

Becan
Becan ( Spanish: Becán) is an archaeological site of the Maya civilization in pre-Columbian Mesoamerica. Becan is located near the center of the Yucatán Peninsula, in the present-day Mexican state of Campeche, about 150 km (93.2 mi) north of Tikal. The Maya sites of Balamku, Calakmul, Chicanna and Xpuhil are nearby. The name ''Becan'' was bestowed on the site by archaeologists who rediscovered the site, meaning "ravine or canyon formed by water" in Yukatek Maya, after the site's most prominent and unusual feature, its surrounding ditch. History Archaeological evidence shows that Becan was occupied in the middle Preclassic Maya period, about 550 BCE, and grew to a major population and ceremonial center a few hundred years later in the late Preclassic. The population and scale of construction declined in the early classic (c 250 CE), although it was still a significant site, and trade goods from Teotihuacan have been found. A ditch and ramparts were constructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disturbance (archaeology)
A disturbance is any change to an archaeological site due to events which occurred after the site was laid down. Disturbances may be caused by natural events or human activity, and may result in loss of archaeological value. In some cases, it can be difficult to distinguish between features caused by human activity in the period of interest, and features caused by later human activity or natural processes. Causes Natural causes The soil science, soil scientist Francis D. Hole identified nine natural processes resulting in soil disturbance, including the movements of animals and plants (known as bioturbation, and including burrowing, root growth and tree uprooting, treefalls); freezing and thawing; movement under gravity (including earthflow and rockslides); swelling and shrinking of clays; the actions of wind and water; the growth and dissolution of salt crystals; and movement caused by earthquakes. Different sites are subject to different degrees, combinations, and interactio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceramic
A ceramic is any of the various hard, brittle, heat-resistant, and corrosion-resistant materials made by shaping and then firing an inorganic, nonmetallic material, such as clay, at a high temperature. Common examples are earthenware, porcelain, and brick. The earliest ceramics made by humans were fired clay bricks used for building house walls and other structures. Other pottery objects such as pots, vessels, vases and figurines were made from clay, either by itself or mixed with other materials like silica, hardened by sintering in fire. Later, ceramics were glazed and fired to create smooth, colored surfaces, decreasing porosity through the use of glassy, amorphous ceramic coatings on top of the crystalline ceramic substrates. Ceramics now include domestic, industrial, and building products, as well as a wide range of materials developed for use in advanced ceramic engineering, such as semiconductors. The word '' ceramic'' comes from the Ancient Greek word (), meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollen
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male Conifer cone, cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it Germination, germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and Forensic science, forensics. Pollen in plants is used for transferring Ploidy#Haploid and monoploid, haploid male genetic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytolith
Phytoliths (from Greek language, Greek, "plant stone") are rigid, microscopic mineral deposits found in some plant tissues, often persisting after the decay of the plant. Although some use "phytolith" to refer to all mineral secretions by plants, it more commonly refers to Silicon dioxide, siliceous plant remains. Phytoliths come in varying shapes and sizes. The plants which exhibit them take up dissolved silica from the groundwater, whereupon it is deposited within different intracellular and extracellular structures of the plant.Piperno, Dolores R. (2006). Phytoliths: A Comprehensive Guide for Archaeologists and Paleoecologists. AltaMira Press . The silica is absorbed in the form of orthosilicic acid, monosilicic acid (Si(OH)4), and is carried by the plant's Circulatory system, vascular system to the cell walls, cell lumen, and intercellular spaces. Depending on the plant Taxon, taxa and soil condition, absorbed silica can range from 0.1% to 10% of the plant's total dry weight ...

Aerial Photography
Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other flight, airborne platforms. When taking motion pictures, it is also known as aerial videography. Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs or "drones"), balloon (aircraft), balloons, blimps and dirigibles, rockets, pigeon photography, pigeons, kite aerial photography, kites, or using action cameras while skydiving or wingsuiting. Handheld cameras may be manually operated by the photographer, while mounted cameras are usually remote operation, remotely operated or triggered automatically. Aerial photography typically refers specifically to bird's-eye view images that focus on landscapes and Earth surface, surface objects, and should not be confused with air-to-air photography, where one or more aircraft are used as chase planes that "chase" and photograph other aircraft in flight. Elevated photography can also produce b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sabal
''Sabal'' is a genus of New World palms (or fan-palms). Currently, there are 17 recognized species of ''Sabal'', including one hybrid species. Distribution The species are native to the subtropical and tropical regions of the Americas, from the Gulf Coast/South Atlantic states in the Southeastern United States, south through the Caribbean, Mexico, and Central America to Colombia and Venezuela. Description Members of this genus are typically identified by the leaves which originate from a bare, unarmed petiole in a fan-like structure. All members of this genus have a costa (or midrib) that extends into the leaf blade. This midrib can vary in length; and it is due to this variation that leaf blades of certain species of ''Sabal'' are strongly curved or strongly costapalmate (as in ''Sabal palmetto'' and ''Sabal etonia'') or weakly curved (almost flattened), weakly costapalmate (as in ''Sabal minor''). Like many other palms, the fruit of ''Sabal'' are drupe, that typically c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
