Name Details:
Identified By:  Frank A. Weir
Named For:  
Date Identified:  1984
Type Site:  Wilson-Leonard Site (41WM235), Williamson County, Texas
Point Validity: Valid type

Watt was a professional lithographic artist who became interested in archaeology.  He was the founder of the Central Texas Archaeological Society and was the editor for the Central Texas Archaeologist Journal.  Weir conducted extensive studies and excavations at the Wilson-Leonard site from 1982 until 1984.  This type was named in a professional publication and has many professional references.  This is considered a valid type.  Hester et al (2011) point out that additional research is needed on this type.
Thrall Lanceolate
AKA: Thrall Angostura
Cluster:
Description of Physical Characteristics and Flaking Pattern:
This is a medium to large stemmed lanceolate point with an elliptical cross section.  The blade is excurvate with the blade curving in at the tip and having parallel edges.  The shoulder is weak to absent and at an upward angle.  The stem is thick and straight with a base that is slightly concave to concave.  The stem is long and may make up to one third to one half the total length of the point.  Heavy basal and hafting region grindings is present on this type.  The flaking pattern may vary from random to horizontal or parallel oblique.
Size Measurements:

Length - 50 to 105 mm, Blade Width - 18 to 42 mm,  Thickness - 9 mm average

Additional Comments:

This point is similar to the coastal Victoria type, but lacks the expanding stem that is seen on the Victoria type.  Perttula (2004) argues that this may represent a central Texas variation of the Victoria type.  The Thrall type is found in central Texas while the Victoria and Zella types are found on the Coastal and coastal plains region.  Sites containing both types have not been found so temporal position is unknown.  However, he notes that this point is found above levels containing Angostura points which might make them slightly newer than the Victoria type which are found in the same levels as Angostura points. 

Most researches consider this a variant of the Angostura type and will sometimes hyphenate the name Angostura - Thrall.  However, Waters and Jenning (2015) include this as a Hell Gap variant and hyphenate this type Hell Gap - Thrall.
