Lamoka projectile points are stone projectile points manufactured by Native Americans what is now the northeastern United States, generally in the time interval of 3500-2500 B.C. They predate the invention of the bow and arrow, and are therefore not true "arrowheads", but rather atlatl dart points. They derive their name from the specimens found at the Lamoka site in Schuyler County, New York.
Lamoka points sizes range in length from less than an inch to 2½ inches with an average of about 1½ inches. They are narrow and thick, with straight or slightly notched stems. The base is thick and this is diagnostic for the Lamoka point. They are two to three times longer than they are wide. They are generally made from local flints, jasper, quartz and quartzite. There are a number of varieties, the most common being the "stemmed" type with straight stems.
They have mostly been dated to around 3500-2500 BC, but the type persists in small numbers up to about 1000 A.D. The archaic points are associated with the Lamoka culture.
Clovis points are the characteristically-fluted projectile points associated with the New World Clovis culture. They are present in dense concentrations across much of North America; in South America, they are largely restricted to the north of that continent. Clovis points date to the Early Paleoindian period roughly 13,500 to 12,800 calendar years ago. Clovis fluted points are named after the city of Clovis, New Mexico, where examples were first found in 1929 by Ridgely Whiteman.A typical Clovis point is a medium to large lanceolate point. Sides are parallel to convex, and exhibit careful pressure flaking along the blade edge. The broadest area is near the midsection or toward the base. The base is distinctly concave with a characteristic flute or channel flake removed from one or, more commonly, both surfaces of the blade. The lower edges of the blade and base are ground to dull edges for hafting. Clovis points also tend to be thicker than the typically thin later-stage Folsom points. with length ranging from 4 to 20 centimetres (1.6 to 7.9 in) and width from 2.5 to 5 centimetres (0.98 to 1.97 in). Whether the points were knife blades or spear points is an open question.Folsom point
Folsom points are a distinct form of knapped stone projectile points associated with the Folsom tradition of North America. The style of tool-making was named after the Folsom Site located in Folsom, New Mexico, where the first sample was found by George McJunkin within the bone structure of a bison in 1908. The Folsom point was identified as a unique style of projectile point in 1926.Projectile point
In archaeological terms, a projectile point is an object that was hafted to weapon that was capable of being thrown or projected, such as a spear, dart, or arrow, or perhaps used as a knife. They are thus different from weapons presumed to have been kept in the hand, such as axes and maces, and the stone mace or axe-heads often attached to them.
Stone tools, including projectile points, can survive for long periods, were often lost or discarded, and are relatively plentiful, especially at archaeological sites, providing useful clues to the human past, including prehistoric trade. A distinctive form of point, identified though lithic analysis of the way it was made, is often a key diagnostic factor in identifying an archaeological industry or culture. Scientific techniques exist to track the specific kinds of rock or minerals that used to make stone tools in various regions back to their original sources.
As well as stone, projectile points were also made of worked bone, antler or ivory; all of these are less common in the Americas. In regions where metallurgy emerged, projectile points were eventually made from copper, bronze, or iron, though the change was by no means immediate. In North America, some late prehistoric points were fashioned from copper that was mined in the Lake Superior region and elsewhere.
