Here’s an interesting Paleoindian biface made from banded Alibates chert. It was apparently discovered by a local resident in the early 1970s. The tool (knife) measures about 12 cm (4 3/4″) and is remarkably thin, with flaking consistent with other Clovis bifaces from the site. I have used this, as well as other unusual specimens to demonstrate the wide variety of lithic tools that are part of the tool kit that are often overlooked in the popular media. Although we cannot be certain as to it’s exact temporal placement, based on morphology, the area where it was recovered and information from the finder, I think it is most likely Clovis in age, but we will never be certain.
I decided to post this today as one of our graduate researchers, Stacey Bennett just came across the original field note from when it was returned to the Landmark in 1984.
