Greenbrier Side Notch
Cluster: Large Side Notch Cluster
Description of Physical Characteristics and Flaking Pattern:
This is a medium to large triangular side notch point with a flattened to convex cross section.  The blade is primarily excurvate.  Fine serrations are commonly seen on the blade.  Notches are broad and shallow forming shoulders that may vary from horizontal to having a upward slope and weak.  The stem is expanding.  The base may range from straight to concave.  The hafting region has heavy grinding.   This point has a random flaking pattern.
Size Measurements:

Total Length - 40 to 80 mm (average 56 mm),  Stem Length - 8 to 16 mm,  Width - 20 to 38 mm (average 23 mm), Stem Width - usually 20 to 30 mm, Thickness - 4 to 8 mm (average 7 mm)

Additional Comments:

Justice (1987), places this point in the Dalton cluster. The Dalton Greenbrier was placed in the Dalton cluster, but this point was placed in the Large Side Notch cluster due to morphological correlations.

This point has many variation of the base which can make this point difficult to identify. The base can be; straight, lobbed, concave, eared, or bifurcated. some key identification keys are heavy haft region grinding and fine secondary edge flaking (W10)

Also see Florida Greenbrier for variations of this type found in the Gulf Coastal region.
Distribution:
Distribution Comments:

This point is found through out the Tennessee River Valley, lower Mississippi Valley, and into the Gulf coastal region.  This point may rarely be found into central Florida.
