It was John Witthoft who intuited the connection of fluted points to the pleistocene era and their exclusivity to it who coined the term "paleoindian" (formerly paeleoindian) (Shoop Site report, 1952). Previous to this, fluted points were commonly referred to as "Folsoms," and no one was sure whether or not they may have been a special type (possibly ceremonial) made by all, or many later peoples.
Witthoft established the entire context/contextual boundaries, at one stroke.
