Lithic Period
In the sequence of cultural stages first proposed for the archaeology of the Americas by Gordon Willey and Philip Phillips in 1958, the Lithic stage was the earliest period of human occupation in the Americas, as post-glacial hunter gatherers spread through the Americas. The stage derived its name from the first appearance of Lithic flaked stone tools. The term Paleo-Indian is an alternative, generally indicating much the same period. This stage was conceived as embracing two major categories of stone technology: (1) unspecialized and largely unformulated core and flake industries, with percussion the dominant and perhaps only technique employed, and (2) industries exhibiting more advanced "blade" techniques of stoneworking, with specialized fluted or unfluted lanceolate points the most characteristic artifact types. Throughout South America, there are stone tool traditions of the lithic stage, such as the "fluted fishtail", that reflect localized adaptations to the divers ...

Archaeology Of The Americas
The archaeology of the Americas is the study of the archaeology of the Western Hemisphere, including North America (Mesoamerica), Central America, South America and the Caribbean. This includes the study of pre-historic/Pre-Columbian and historic indigenous American peoples, as well as historical archaeology of more recent eras, including the Trans-Atlantic slave trade and European colonization. Chronology The Pre-Columbian era is the term generally used to encompass all time period subdivisions in the history of the Americas spanning the time from the original settlement of the Americas in the Upper Paleolithic until the European colonization of the Americas during the early modern period. While technically referring to the era before the voyages of Christopher Columbus from AD 1492 to 1504, in practice the term usually includes the history of American indigenous cultures until the 18th or 19th century. In more recent decades, archaeological scholarship has extended to inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back ...

Knives
A knife ( : knives; from Old Norse 'knife, dirk') is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone (such as flint and obsidian), over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin. Knives can serve various purposes. Hunters use a hunting knife, soldiers use the combat knife, scouts, campers, and hikers carry a pocket knife; there are kitchen knives for preparing foods (the chef's knife, the paring knife, bread knife, cleaver), table knives (butter knives and steak knives), weapons (daggers or switchblades), knives for throwing or juggling, an ...

Laurentide Ice Sheet
The Laurentide Ice Sheet was a massive sheet of ice that covered millions of square miles, including most of Canada and a large portion of the Northern United States, multiple times during the Quaternary glacial epochs, from 2.58 million years ago to the present. The last advance covered most of northern North America between c. 95,000 and c. 20,000 years before the present day and, among other geomorphological effects, gouged out the five Great Lakes and the hosts of smaller lakes of the Canadian Shield. These lakes extend from the eastern Northwest Territories, through most of northern Canada, and the upper Midwestern United States (Minnesota, Wisconsin, and Michigan) to the Finger Lakes, through Lake Champlain and Lake George areas of New York, across the northern Appalachians into and through all of New England and Nova Scotia. At times, the ice sheet's southern margin included the present-day sites of coastal towns of the Northeastern United States, and cities such as Bos ...

LSU Campus Mounds
The LSU Campus Mounds or LSU Indian Mounds are two Native American mounds, likely of the Archaic Period, on the campus of Louisiana State University in Baton Rouge, Louisiana. The mounds are commonly thought to be more than 5,000 years old, and one estimate places them at 11,300 years old. They predate the Great Pyramids of Egypt, and are believed to be the oldest surviving man-made structure in the Americas, or possibly the whole world. History The mounds were built thousands of years ago on a spot overlooking the floodplain of the Mississippi River in what is now Baton Rouge, Louisiana, and the site of Louisiana State University. The northern mound consists of hard clay dirt; the southern mound is more porous. The scholarly consensus is that they were used for "ceremonial and marking point purposes," rather than for burial. They are part of a larger, statewide system of mounds. They were first dated in 1982. In 2009, LSU professor Brooks Ellwood took core samples that revea ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Paisley Caves
The Paisley Caves or the Paisley Five Mile Point Caves complex is a system of eight caves in an arid, desolate region of south-central Oregon, United States north of the present-day city of Paisley, Oregon. The caves are located in the Summer Lake basin at elevation and face west, carved into a ridge of Miocene and Pliocene era basalts mixed with soft volcanic tuffs and breccias by Pleistocene-era waves from Summer Lake. One of the caves may contain archaeological evidence of the oldest definitively-dated human presence in North America. The site was first studied by Luther Cressman in the 1930s. Scientific excavations and analysis in the Paisley Caves since 2002 have uncovered substantial new discoveries, including subfossil human coprolites with the oldest DNA evidence of human habitation in North America, various artifacts, and animal remains. The DNA was radiocarbon dated to 14,300 BP or roughly 12,000 BCE. The caves were added to the National Register of Historic Places in ...

Coprolite
A coprolite (also known as a coprolith) is fossilized feces. Coprolites are classified as trace fossils as opposed to body fossils, as they give evidence for the animal's behaviour (in this case, diet) rather than morphology. The name is derived from the Greek words κόπρος (''kopros'', meaning "dung") and λίθος (''lithos'', meaning "stone"). They were first described by William Buckland in 1829. Before this, they were known as "fossil fir cones" and "bezoar stones". They serve a valuable purpose in paleontology because they provide direct evidence of the predation and diet of extinct organisms. Coprolites may range in size from a few millimetres to over 60 centimetres. Coprolites, distinct from ''paleofeces'', are fossilized animal dung. Like other fossils, coprolites have had much of their original composition replaced by mineral deposits such as silicates and calcium carbonates. Paleofeces, on the other hand, retain much of their original organic composition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
