This chert Montell point is from Texas and dates to the Cibolo phase of the Late Archaic period, ca. 2400-2800 BP.
Montell points were made and used on the central Rio Grande River and are found in southwestern Texas and northeastern Mexico. They were dart points thrown with spearthrowers, and have been excavated from bison kill sites in Texas, such as Bonfire Shelter. The manufacturing sequence for these points is unusual because the proximal basal notches were sometimes made early in the process, before the distal end was thinned and shaped. This contrasts with most other North American biface technologies, which involved making the notches at the end of the manufacturing sequence. The point in this model was abandoned after it was notched but before the distal end was finished.
