PLAINVILLE PLANO POINTS
Late Paleo-Indian: 10,000 to 9,500 BP
DESCRIPTION: Plainville Plano points range in size from
30 to 178 mm in length, 20 to 46 mm in width, and 4 to 10 mm in
thickness. Basal width is 15 to 23 mm. These points are gently
expanding lanceolates with a long tapering tip section. Basal
configuration is most distinctive with a straight to slightly
incurvate "square" base, weak basal ears, and small
lateral edge notches 6 to 12 mm above the base. They display light
basal and lateral edge grinding and the cross section is plano-convex
to biconvex. Surface flaking generally consists of shallow, medium
width, parallel sided percussion flake scars in an overall collateral
pattern leaving a median ridge on both faces of the point.
DISTRIBUTION: These points have a very broad range, occurring
from near Leamington on south western Ontario, north to the Ontario
Island uplands near Flesherton (Stork 1972), and east to Ancaster,
near Hamilton and Rice Lake in south central Ontario (Jackson
1997).
RAW MATERIAL: Points are known primarily on Onondaga chert
but also include examples of Bayport chert and Manitoulin formation
quartzite.
AGE AND CULTURE: 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.
