Type Lanceolate Middle-Archaic
The Guilford point has a long, slender, but thick blade with a straight, rounded or concave base.
The Guilford point dates to the Middle Archaic period, 4200 to 3500 BCE. Coe (1964) dates this point to around 4000 BCE based on radiocarbon dates obtained from the Gaston Site in North Carolina.
The base of the Guilford may be flat, rounded, or concave. The shouldered form is considerable later and may date as late as 3000 BCE, based on a radiocarbon date from Cactus Hill, Virginia (McAvoy & McAvoy 1997).
Defined in Literature
Coe (1964) notes that the Guilford point type has been found in great numbers in the South Appalachian area, but has hardly been mentioned in the literature. Coe was the first to publish a brief description of the Guilford type in 1952. Additionally, the Guilford type is discussed by Coe in 1964 based on points recovered from the Doerschuk Site and the Gaston Site in the Piedmont of North Carolina.
