The Goal of the Gatecliff Projectile Point Typology Was

The goal of the Gatecliff projectile point typology was:

A) to distinguish between arrow and dart points (in other words, to determine functional differences) .
B) to determine differences in the frequencies of raw material types used in projectile point manufacture through time.
C) to define temporal types that could then be used to estimate the age of surface assemblages.
D) None of the answers; the Gatecliff typology had no goal and illustrates the problems inherent in typologies that are not associated with particular research questions.
