Astolfo G. Araujo 2. Lithic bifacial points are very common in the southern and southeastern regions of the Brazilian territory. Dated from Early to Late Holocene, these artifacts have not been studied in terms of their propulsion system. Given the characteristics of the bow and arrow compared to the atlatl and dart, there are important differences in the size and weight of arrowheads and dart points. Applying the techniques proposed by Shott , Bradbury , Fenenga , Hughes , and Hildebrandt and King to specimens recovered from eight sites dating from the early to the late Holocene, this work aims to present preliminary results to better understand the potential presence of darts and arrows in southeastern and southern Brazil. There was a variation in the results according to the application of different techniques. At least one set of points, dated from the Early Holocene, presented quite a high proportion of specimens classified as arrows, indicating the presence of points that could be used as arrowheads.
Clovis Projectile Point
Two fluted points from this collection, pictured above, are on display in Pennsylvania Icons at The State Museum. Fluted projectile points are lanceolate in shape, averaging 4-to-8 centimeters long with a flute or groove extending from the base to nearly the entire length of the point. Fluted points are the hallmark artifact of the Paleoindian period and, arguably, the most difficult stone artifact ever to be made in North America. Dating to between 13, to 12, years ago, the points are unique to this time period and are only found in North America.
The Paleoindian period dates to the Pleistocene or Ice Age. Covering roughly 35 acres, the area remains one of the largest Paleoindian sites in the commonwealth.

At the Gault archaeological site in central Texas, archaeologists have unearthed a projectile point technology never previously seen in North America, which they date to be 16,, years old. The findings , published in the journal Science Advances , suggest humans occupied the North American continent prior to Clovis — considered the first culture to use projectile points to hunt on the continent, and dated to around 11, years ago.
Image credit: N. For decades, scientists believed the Western Hemisphere was settled by humans roughly 13, years ago, a theory based largely upon the widespread distribution of Clovis artifacts dated to that time. Now, Texas State University researcher Thomas Williams and colleagues, working at the Gault site northwest of Austin, has dated a significant assemblage of stone artifacts to 16,, years of age, pushing back the timeline of the first human inhabitants of North America far before Clovis.
Williams said. Excavations below the Clovis deposits revealed well-stratified sediments containing artifacts — called Gault Assemblage — distinctly different from Clovis.

For the past 2. Rock has been our friend! Projectile points and stone tools are great ways to see how cultures have changed over time and to pinpoint who was at a particular archaeological site at a given time. Odds are that where there were people, there were projectile points, more commonly known as arrowheads. As cultures evolve, so too does the material, shape, style and use of their stone tools, making them a great way for archaeologists to track cultural shifts and evolutions.
Our fair state has played a pivotal role in the tracking, dating and discovery of projectile points. New Mexico is the namesake for two of the most famous types of projectile point cultures found on this continent. The Clovis and the Folsom cultures dominated stone tool making in North America for about 4, years, give or take a couple of centuries.

Projectile weapons i. Projectiles therefore provided a significant advantage over thrusting spears. Composite projectile technologies are considered indicative of complex behavior and pivotal to the successful spread of Homo sapiens. In combination with the existing archaeological, fossil and genetic evidence, these data isolate eastern Africa as a source of modern cultures and biology.
Using a collection of projectile points from well-dated contexts in Montana and Wyoming, we have developed a mathematical technique for.
This page is your gateway to two types of point typology indexes:. The assumption in using this index is that you know the type and want to view information about the type. The Shape Index is my newest index. It is designed to help you identify a projectile point type that you may not know the name of. The shape or morphology index is organized by 10 major hafting area shape groups. An explanation and example for using the shape index is provided at the top of that index.

Ripley P. Bullen collected information about Florida Projectile Points from avocational and professional archaeologists for decades. First presenting his typology in the s, this work was meant as a starting point to understand stone tool types that could be refined and built upon through the years See Bullen History.
This illustrated version is something both groups have shown an interest in for years and why we have photographed each of the over projectile points that have come to be referred to as the Bullen Projectile Point Type Collection. We hope this highly-sought-after resource will be of use. It is not meant to be a treatise on the state of stone tool typology but rather a simple reference tool for comparative research and researchers.
Projectile point, around 5 cm long and 2 cm wide at widest point. around it to tell archeologists when it might date to or who left it there.
Post a Comment. The period between and years ago is the most poorly understood time in the prehistory of the Middle Atlantic region. The reason it is difficult to recognize, is that the usual diagnostic artifacts, such as projectile points are not very distinctive and are easily confused with point types from other periods. We are dependent on radiocarbon dates to confidently identify this period in the archaeological record and C samples are not always available. The Middle Archaic period dates between and years ago and begins during the warm and dry Boreal climatic episode.
A pine and birch forest was gradually changing to a pine-oak forest during this time. The beginning of this period is characterized by bifurcate based projectile point types such as MacCorkle, St. Albans and LeCroy types. These are distinguished from other points by a bifurcated base – a deep notch in the base of the point. They are very distinctive and although there is a great deal of variation in the shape of the blade and the nature of the bifurcation, there are no other projectile points like these in the eastern United States and in Pennsylvania they date between and years ago.
We know this because charcoal associated with bifurcate points has been radiocarbon dated at several sites and except for a few outliers, the dates fall within this time range. This pattern established from tested sites, allows us to assign them to the Middle Archaic, even when they are found on the ground surface and not associated with carbon 14 dates.
Oh no, there’s been an error
Arrowheads are among the most easily recognized type of artifact found in the world. Untold generations of children poking around in parks or farm fields or creek beds have discovered these rocks that have clearly been shaped by humans into pointed working tools. Our fascination with them as children is probably why there are so many myths about them, and almost certainly why those children sometimes grow up and study them.
Here are some common misconceptions about arrowheads, and some things that archaeologists have learned about these ubiquitous objects. Arrowheads, objects fixed to the end of a shaft and shot with a bow, are only a fairly small subset of what archaeologists call projectile points. A projectile point is a broad category of triangularly pointed tools made of stone, shell, metal, or glass and used throughout prehistory and the world over to hunt game and practice warfare.
Dating of the site relied on only two recovered projectile points, the only diagnostic tools found, and a radiocarbon sample collected from a feature.
Clovis points have been found across North America and northern South America. Typical examples are medium to large lanceolate points, with convex sides broadest near the midsection or toward the base. The base of the point is concave, and the characteristic long, shallow grooves, or flutes , appear on one or more commonly both sides of the point. The flutes likely made it easier to fasten the points to wooden spears, atlatl dart shafts and handles.
Edgar B. Howard, an archaeologist working with the University of Pennsylvania Museum of Archaeology and Anthropology, identified the Clovis point in , during investigations of a gravel pit along a stream near the town of Clovis, New Mexico. He found them in close association with the bones of Pleistocene animals, such as mammoths, bison and camels, the first evidence that Paleoindians lived alongside the Ice Age megafauna.
Projectile Point Typology and Dating
Evidence from the Cooper’s Ferry archaeological site in Western Idaho shows that people lived in the Columbia River Basin around 16, years ago. That’s well before a corridor between ice sheets opened up, clearing an inland route south from the Bering land bridge. That suggests that people migrated south along the Pacific coast.
Stone tools from the site suggest a possible connection between these first Americans and Northeast Asian hunter-gatherers from the same period. A piece of charcoal unearthed in the lowest layer of sediment that contains artifacts is between 15, and 15, years old, according to radiocarbon dating. More charcoal, from the remains of an ancient hearth pit, dated to between 14, and 15, years old.

Each high-quality color photograph is accompanied by an up-to-date summary of the age of each point type. Coupled with the concise directions for describing projectile point forms, the guide provides an effective means of quickly identifying the type and age of points likely to be encountered throughout the state. The comprehensive visual record of points from Iowa contexts is unavailable in any other context.
Beautifully designed and illustrated with sixty-one type specimens from Iowa archaeological sites, this two-part guide offers quick reference for field identification of the age, cultural affiliation, and materials of artifacts that are collected by the thousands each year. In addition, the guide offers ethical guidelines that balance the enjoyment of artifact hunting with contributions to our collective knowledge.
This guide should be carried by all collectors and field archaeologists and should be on hand for all Iowa museums that have Native American artifact collections or patrons who bring them in for identification. Available now for the first time, the Guide to Projectile Points of Iowa prepared by veteran Iowa archaeologist Joe Tiffany considers nearly fifty stone arrow and spear point types found in Iowa and adjacent states. The many Native Americans who have inhabited Iowa shaped points primarily of various cherts and chalcedonies found locally or traded regionally.
The single point types illustrated in this two-part guide, the first to provide color photographs to scale for all types found in Iowa, show the wide range of variability as forms evolved from the Paleoindian period, 11,—10, BC, to the Late Prehistoric period, AD — The two beautifully illustrated parts depict a total of sixty-one full-size stone point types in color by archaeological period.

Projectile-point typology, cross dating, and strati graphic position were the primary bases for this hypothesized chronology and are critiqued here in some detail.
Most of the historic artifacts date to the 19th century and most likely represent refuse-disposal or manuring associated with nearby farms. Most of the stone artifacts represent waste material or debitage discarded during the manufacture of stone tools. Such artifacts are very common at prehistoric sites where stone tools were manufactured and re-sharpened. The manufacture of a single tool might result in the production of hundreds of small flakes of stone. Nearly stone tool fragments were also found.
Over half of these are projectile point fragments or unfinished tools that were probably meant to be made into projectile points or knives. Thirty-two of the tools found represent scrapers and similar fragments of reworked flakes. These general-purpose tools were likely used for a variety of tool-manufacturing and food-processing tasks. Some other interesting artifacts include a partially finished spear-thrower atlatl weight, a paint stone of red Location of lithic materials in relation to Canterbury, Connecticut pigment, and two stone drills.
The oldest projectile point type found dates to between 8, and 7, years ago.
