SIZE: Length = 30-178 mm (mean of 83 mm)
Width= 20-46 mm (mean of 30 mm)
Thickness = 4-10 mm (mean of 6 mm)
Basal Width = 15-23 mm (mean of 21 mm)
SHAPE: These points are gently expanding lanceolates with a long and tapering tip section. Basal configuration is most distinctive with a straight to slightly incurvate “square” base, weal basal ears, small lateral edge notches 6 to 12 mm above the base, plano-convex to biconvex cross-section, and light basal and lateral edge grinding.
FLAKING: Surface flaking generally consists of shallow, medium width, parallel-sided flake scars in an overall collateral pattern leaving a median ridge on both faces of the point.
RAW MATERIAL: Points are known primarily on Onondaga chert but also include examples of Bayport chert and Manitoulin formation quartzite.
DISTRIBUTION: These points have a very broad range, occurring from near Leamington in southwesternmost Ontario (P. Lennox, Personal communication), north to the Ontario Island uplands near Flesherton (Storck, 1972), and east to Ancaster, near Hamilton (Griffin-Short, 1997: Personal communication) and Rice Lake in south-central Ontario (Jackson 1997).
AGE AND CULTURAL AFFILIATION: There are no dated contexts yet for these points. However, flaking characteristics and morphological attributes support an age circa 10,000 to 9,500 B.P in the late Paleo-Indian period.
COMMENTS: The Plainville point has no exact parallel in the Late Plaeo-Indian Plains sequence but is similar to the unfluted Midland and Plainview types. Prufer (1963) illustrates a similar, but more broadly expanding late Paleo-Indian lanceolate from the McConnell site in Ohio.
