Erb Point

This basal notch point exhibits a compact to moderate size, characterized by an elliptical profile. Its blade displays a predominantly excurvate shape, with a subtle curvature that converges towards the base, forming a distinctive drooping barb effect at the shoulder. The barbed shoulders extend downward, merging with the base of the point. The stem presents a range of forms, from straight to slightly expanding, while the base remains straight-edged. The flaking pattern on this point appears to be random, lacking a discernible order or sequence.

The dimensions of the arrowheads are as follows: they typically range in length from 28 to 50 mm, with a mean length of 30 to 40 mm. The stem measures between 3 to 6 mm in length, averaging 4 mm. In terms of width, the blade spans 22 to 35 mm, with an average width of 30 mm. The stem width varies from 8 to 15 mm, with a mean stem width of 10 mm.

This type is mainly located from the middle to the eastern parts of Pennsylvania, extending into New Jersey and Delaware.
