There are slight differences in points found in the Eastern United States bringing them to sometimes be called "Clovis-like".
[15]Specimens are known to have been made of flint, chert, jasper, chalcedony and other stone of conchoidal fracture.
[20][21] One issue is that the sea level is now about 50 meters higher than in the Paleoindian period so any coastal sites would be underwater, which may be skewing the data.
[22] The widespread South American Fishtail or Fell projectile point style has been suggested to have derived from Clovis.
[23] Of the around 6000 points currently classified as Clovis found in the United States the majority were east of the Mississippi and especially in the Southeast.
[32] There is current debate on whether "assemblages", production debris typically found in Clovis sites (blade cores, large bifacial overface flakes, etc.)
[33][34] Whether Clovis toolmaking technology was developed in the Americas in response to megafauna hunting or originated through influences from elsewhere is an open question among archaeologists.
Lithic antecedents of Clovis points have not been found in northeast Asia, from where the first human inhabitants of the Americas originated in the current consensus of archaeology.
Some archaeologists have argued that similarities between points produced by the Solutrean culture in the Iberian Peninsula of Europe suggest that the technology was introduced by hunters traversing the Atlantic ice-shelf and suggests that some of the first American humans were European (the Solutrean hypothesis).
