nodule morphology, material of the cortex and other circumstances. The
cores and/or other variations of Levallois technology (cf. Böeda 1993; Dib
1995:413; Yalçinkaya 1995:319; Wengler 1995:315).
I am aware that the South American Paleoindians might have used dif
ferent kinds of prepared cores. However, one of the alternatives to consider
is the bifacial one, such as it has been discussed here, which might be part
of the variations occurring during the core preparation strategies. There
fore, neither the bifacial prepared cores with asymmetrical or symmetrical
used “bifaces as cores”. Like some Paleoindian groups of North America,
might have resulted in projectile point production (cf. Collins 1999). Be
yond adaptive and social differences, this fact suggests that certain technical
similarities that existed among Paleoindians from North and South America
hint of shared technical knowledge (Nami 1997; n.d.a). Additionally, the use
of prepared cores strategies also implies that during the early times in the
New World archaeology, by diverse historical and social mechanism, human
populations would have shared some kind of technological information.
