A Mathematical Techique for Dating Projectile Points Common to the Northwestern Plains

Where they came from, and how they got here, is still a matter of dispute. The first humans to occupy North American may have walked here from Siberia, crossing the Bering land bridge as they hunted for game and gathered plant foods. Perhaps 25, years ago, Siberians migrated into Beringia. They may have stayed there for 10, years during the Last Glacial Maximum, isolated on a 1, mile wide grassland of northwestern Siberia and far western Alaska, plus what is now the seafloor beneath the Bering Strait. On the east, the Cordilleran Ice Sheet covered the mountains along Alaska’s coastline and icebergs calved off the edge into the Pacific Ocean. The two ice sheets extended from the frozen Arctic Ocean to the Pacific Ocean. A complete barrier of ice is presumed to have blocked humans from moving into the interior of Alaska or the rest of North America, and 17, years ago the Cordilleran Ice Sheet stretched westward to the edge of the continental shelf off the coast of British Columbia. Unlike Columbus in , they were not consciously on a journey to discover a new path to the other side of the world.

The only explanation for such symmetry across these vast distances, explains Smithsonian anthropologist Dennis Stanford, is that the method of creating the points was handed down from person to person. Clovis stone points from the Drake Cache of Colorado. Radiocarbon dating of the stone points backs this theory. The Colby and Drake points have markedly different bases, but this difference is much less prominent in the flake scar contours. For the two modern replicas, their flake scar contours are generally more uneven, and also display larger differences between the overlaid contours.

The earliest prehistoric human occupation in North Carolina dates to the Paleo-Indian period, which is thought to have begun around 10, BC.

Blade Core This artifact was used to provide stone blades. Blade cores provided a portable source of stone or obsidian for manufacturing different kinds of tools by flaking off pieces from the core. Blade flakes were “pre-forms” that could be fashioned into knives, hide scrapers, spear tips, drills, and other tools.

End Scraper This artifact was used for scraping fur from animal hides. For European and American Stone Age peoples, end scrapers served as heavy- duty scraping tools that could have been used on animal hides, wood, or bones. Once the hide was removed from an animal, an end scraper could take the hair off the skin’s outer layer and remove the fatty tissue from its underside.

End scrapers were sometimes hafted, or attached to a wooden handle, but could also be handheld. Burin This artifact was used for carving bone, antler, or wood. Burins are among the oldest stone tools, dating back more than 50, years, and are characteristic of Upper Paleolithic cultures in both Europe and the Americas. Burins exhibit a feature called a burin spall—a sharp, angled point formed when a small flake is struck obliquely from the edge of a larger stone flake.

These tools could have been used with or without a wooden handle. Awl This artifact was used for shredding plant fibers.

Straight parabolic fletchings on an arrow. Coat of arms of Poprad in Slovakia. An arrow as a heraldic symbol. Fletchings are found at the back of the arrow and act as airfoils to provide a small amount of force used to stabilize the flight of the arrow. They are designed to keep the arrow pointed in the direction of travel by strongly damping down any tendency to pitch or yaw. Some cultures, for example most in New Guinea , did not use fletching on their arrows.

High-resolution outline data from Late Woodland triangle projectile points is studied. Lithic analysts have questioned two types of triangle, Levanna and Madison, as valid analytic units as they are quantifiably indeterminate when measured using caliper methods such as length and width. The geometric morphometric analysis here takes outline data from a previously studied collection of projectile points and uses elliptical Fourier harmonics analysis combined with principal components and discriminant functions tests to objectively define and separate the two types of projectile point.

The result is a bimodal distribution of types that conforms to the traditional typological classification system for the region, in contrast to recent scholarship that conflates the two types into one. This study describes a high-resolution technique that offsets the inherent drawbacks of subjective, coarse-grained measurement approaches to projectile point characterization and comments on the study of typology as a whole.

Scientists expected to find them there. About kilometers [ miles] northeast of Las Vegas, researchers from the Utah -based firm Logan Simpson discovered 19 separate sites containing a variety of stone points, biface blades, and other artifacts associated with the Paleoarchaic Period, an era ranging from 7, to 12, years ago. Though scant and widely scattered, these pieces may help clarify the hazy history of human activity throughout the Great Basin , when the Ice Age gave way to a warmer and more stable climate.

By identifying the qualities that previously known locations had in common, the archaeologists predicted where other, similar sites might be waiting to be found. After mapping the land with GIS, aerial photos, and other tools, the researchers pinpointed and then ranked the most promising locations in the study area. The sites included scatterings of fluted and stemmed projectile points fashioned in styles — such as Clovis , Lake Mojave and Silver Lake — that are known to date to the Paleoarchaic epoch in the Great Basin , Adams said.

Likewise, at the nearby Dry Lake Valley, the team detected six more sites, along the shoreline of the extinct lake that gave the valley its name. Photo by Zac Scriber, GISP There, researchers found more stone points from the Paleoarchaic, but also many others dating from more recent periods, indicating that these lakeside sites were used many times over the millennia.

A Mayan Jade Hunchback The Big Sandy Point In the study of the typology of projectile points used by prehistoric Americans during the Paleo and Archaic Periods in the Carolinas and Virginia, there seems to be only four types generalized by the point bases. The lanceolate type is straight sided without any notches or stems and is primarily known for the Clovis and Dalton styles of the Paleo Period, circa 10, to 8, BC.

After the Paleo Period ended, with the demise of the large megafauna such as Mammouth, Mastodon and Giant Bison, the point types changed to notched bases and later to stemmed points. The two notched basal types included the corner notched Palmer and Kirk and the side notched styles Hardaway and Big Sandy. These all began during the earliest times in the Archaic Period with a beginning date of at least 8, BC and ending around 6, BC. After that the stemmed type points mostly dominated for the next five or six thousand years.

Fletchings are found at the back of the arrow and act as airfoils to provide a small amount of force used to stabilize the flight of the arrow. They are designed to keep the arrow pointed in the direction of travel by strongly damping down any tendency to pitch or yaw. Some cultures, for example most in New Guinea , did not use fletching on their arrows. Historically, some arrows used for the proofing of armour used copper vanes.

With conventional three-feather fletching, one feather, called the “cock” feather, is at a right angle to the nock, and is normally nocked so that it will not contact the bow when the arrow is shot. Four-feather fletching is usually symmetrical and there is no preferred orientation for the nock; this makes nocking the arrow slightly easier. Natural feathers are usually prepared by splitting and sanding the quill before gluing.

The archaeological site is located in Denali National Park and Preserve Denali and is situated on a loess-mantled granitic bedrock bluff overlooking the glacial-fed Teklanika River. Bedrock landform overlooking the Teklanika River. Coffman Recent excavations at Teklanika West have yielded new data on site chronology and human occupation history. The archaeological site is located in Denali National Park and Preserve Denali and is situated on a loess-mantled granitic bedrock bluff overlooking the glacial-fed Teklanika River Figure 1.

Significant research has taken place at the site by other investigators since the early s cf. These early investigations were largely surface collections of artifacts near the edge of the bluff. West did conduct a series of small excavations at the site Figure 2. West excavating at Teklanika West. NPS Photo Based on these excavations, West interpreted the site to contain two large occupations also referred to in this paper as components.

The first was an undated occupa-tion with numerous artifacts and some large mammal bones, likely moose Alces alces West The second, and older underlying component, was a single undated large occupation, characterized by a microblade-rich assemblage with no associated fauna West , This assemblage along with several other sites in interior Alaska was used by West to define the Denali culture complex dating to approximately 10, years before present B.

Interestingly, there was an older occupation.
