To date, 81 stemmed and barbed preceramic (Archaic) points (8000–900 B.C.) have been identified in Belize. Fifty-four are Lowe points; 21 are Sawmill points. Four more are provisionally classified as Allspice and two as Ya’axche’ points. These stemmed bifaces are frequently beveled on alternate-opposite edges and demonstrate variable degrees of resharpening and reworking, which affects blade shape and tool size. Numerous functions have been attributed to these artifacts; specifically, they have been called spear points, dart points, harpoons, and knives. Metric data from these bifaces, limited macrowear and microwear analyses, and design features, such as barbs and alternate-opposite edge beveling, have been used to interpret likely tool functions. Results suggest that Lowe points were affixed to throwing/thrusting spears and also served as knives, whereas the Sawmill points were used as spear-thrower dart points and as knives. New dating information suggests that alternate-opposite edge beveling and consequently beveled bifaces may be much older than 2500–1900 B.C., which is the date currently assigned to these specimens.

Recent investigations in the Casma Valley on the north-central coast of Peru have uncovered a series of circular and rectangular/square structures, each containing a central hearth associated with either four subfloor ventilation shafts or a single open ventilation trough. The structures date to the Late Preceramic period (2500-1800 B. C.) and the Initial period (1800-900 B. C.). All are small and were originally roofed with perishable materials to hold in heat and smoke from the central hearth. It seems likely that these ventilated hearths represent a coastal variant of the Kotosh Religious Tradition that has been well documented in the Peruvian Highlands. The structures probably served as ritual chambers for small groups of people, somewhat analogous to the sweathouses of various Native American groups.

Maize is claimed to occur occasionally in preceramic deposits in Peru. Cobs, kernels, tassels, pollen, and plant parts have been reported to be associated with Cotton Preceramic period refuse (ca. 2500–1750 B.C., uncorrected) in several north-central coast sites. Maize has been found in some much earlier highland occupations that also have yielded a wide range of ancient dates. These samples represent many types, some with characteristics not found again until late in the first millennium A.D. This arouses suspicion. Checking of artifacts, ecofacts, and radiocarbon dates associated with the maize reveals some that are less than 100 years old and many that are less than 1,500 years old. It also reveals shallow deposits and/or much disturbed context.
