Trujillo Corner Notch
AKA: Basketmaker IIICluster:
Description of Physical Characteristics and Flaking Pattern:
This is a small triangular corner notch point with a flattened cross section. The blade may range from straight to excurvate. Wide notched entre from the corner of the preform forming a shoulder that ranges from slightly barbed to strongly barbed. The stem is expanding with a straight to convex base. This point is commonly crudely made and has a random flaking pattern.
Size Measurements:
Length - 14 to 26 mm (21 mean), Width - 11 to 17 mm (14 mean), Thickness - 2 to 6 mm (3 mm), Neck Width - 4 to 10 mm (7 mm)

Additional Comments:
Irwin-Williams (1971) discussed this type for examples from the En Medio Shelter in New Mexico. She felt that these were "miniature" En Medio points and did not formally define this type.
OLE (1997) notes that these are similar to Rosegate Corner Notch, but tend to have a wider notch than commonly seen on Rosegate points. They note that notch width for the Trujillo type are generally > 4mm while Rosegate points have a notch < 4mm. However, the characteristics of this point were so broad that they decided to classify all small developmental points as Trujillo points.
It is felt that small corner notch points were replaced by side notch points. There seemed to be no corner notch points used after 1,000 A.D. (OLE, 1997).
