THE ORIGINAL CONEHEADS. The heads of the figurines in a second group of JPFs were rendered in a more rudimentary than realistic way. The heads were formed by hand into a cone shape and pinched to make two eyes and a beak-like nose. As with the other type of JPFs, these figurines were painted. While JPFs are divided into two major group types, they can be further categorized into different subgroups. After more than a hundred years of research, the symbolism and function of these JPFs remain uncertain.
