Plainview point
Plainview points are Paleoindian projectile points dated between 10,000–9,000 Before Present. The point was named in 1947 after the discovery of a large cache of unfluted, lanceolate spear tips with concave bases that were found in a ''Bison antiquus'' kill site along the Running Water Draw river, near the town of Plainview in Texas, USA. The point is found primarily throughout the South Plains, however, this range may sometimes be misidentified, as "Plainview" was previously used as a general term to describe unfluted lanceolate points throughout the entirety of the Plains, as well as the eastern Upper Mississippi Valley.〔
==Classification==
The classification of the Plainview point was made in 1947 by Glen Evans, G. E. Meade and E. H. Sellards for a cache of unfluted, lanceolate spear tips with concave bases found along the Running Water Draw river near the town of Plainview in Texas. At least twenty-eight specimens were recovered from this location, which was the site of a ''Bison antiquus'' kill.〔〔 Plainview was previously used as a general term to describe unfluted lanceolate points throughout the entirety of the Plains as well as the eastern Upper Mississippi Valley whereby points were classified as Plainview sub types. However this approach was later rejected and revised leading to new projectile point classifications.〔 The Golondrina point (formally Plainview Golondrina) was one of these types mistakenly named as Plainview.
