PP43A-08 Changes in Paleoindian Projectile Point Densities As Possible Evidence of a Clovis Demographic Collapse in the Southeastern U.S. A. C. Goodyear (803-777-8170; goodyear@sc.edu ) University of South Carolina, South Carolina Institute of Archeology and Anthropology, Columbia, SC 29208, USA [Sponsor: Allen West GeoScience Consulting, Dewey, AZ 86327, USA] South Carolina: Clovis Complex South Carolina: Redstones INTRODUCTION Recent assessment by the creator of the South Carolina Paleoindian point database shows the generous nearness of a suspected Middle Paleoindian point truly known as Redstone (Cambron and Hulse, 1964; Mason, 1962; Perino, 1968; Williams and Stoltman, 1965). At the point when contrasted and the known plenitude of Clovis focuses in South Carolina, a post-Clovis populace decrease is deduced. As a result of late revelations in South Carolina of extensive fluted focuses run of the mill of the Redstone, it turned out to be clear that the Redstone had a straight to trianguloid sharp edge design from the most punctual phase of its utilization life. Lanceolates with to a great degree long conspicuous woodwinds up to this time had been delegated Clovis (Charles and Michie, 1992; Goodyear et al., 1990; Michie, 1977). As needs be, a survey of all fluted focuses yielded a sum of 48 Redstones that had beforehand been misclassified as Clovis. Deduced Population Collapse SOUTH CAROLINA DATABASE REFERENCES Reclassifying the South Carolina database brought about around four Clovis focuses for each one Redstone. Utilizing Clovis and Redstone fluted focuses produced using beach front plain Allendale-sort chert and top notch metavolcanics, a sum of 179 Clovis were discovered versus 40 Redstones (4.5 to 1). Inside the Allendale chert cases, 115 were Clovis versus 24 Redstone (4.8 to 1). Inside metavolcanics, it was 64 Clovis versus 16 Redstones (4 to 1). Expecting Redstones date from 10,800 to 10,500 RCYBP (~12,800 to 12,600 CALYBP), and Clovis dates from 11,300 to 10,900 RCYBP (~13,200 to 12,900 CALYBP), a sharp decrease in post-Clovis fluted focuses is shown. This clear decrease in shot focuses additionally happens amid the Younger Dryas, a period thought to be colder and dryer than Clovis times. No other Paleoindian focuses are known for this region of the Southeast to fill in this day and age. 1. Anderson, D. G., et al. (2005) Current Research in the Pleistocene, 22:91-92. 2.

NORTH CAROLINA AND VIRGINIA RESULTS AND DISCUSSION As a cross-keep an eye on the South Carolina database, the North Carolina Paleoindian point overview was likewise renamed hunting down Redstones. It brought about a Clovis to Redstone proportion of 3 to 1 (Daniel and Goodyear, 2006). This example of a high Clovis to Redstone proportion obviously is not confined to the Carolinas. In his overview of the Nottaway River seepage in southeast Virginia, McAvoy (1992) found a sensational post-Clovis drop in what he calls profound inward based fluted focuses and locales. He proposes a noteworthy populace lessening in this area after Clovis times. For the whole Virginia database, Johnson (1996:205) takes note of that the extent of curved base to apparently Clovis focuses is 11 percent (8 to 1). More consideration ought to be paid to a conceivable post-Clovis, pre-Dalton decrease in Paleoindian indicates in the Southeast decide the archeological reality of this proposed design. Firestone et al. (2005) have hypothesized that an extraterrestrial comet-like effect occasion happened over North America at around 12,900 CALYBP bringing on the onset of the Younger Dryas and the eradication of many expansive ice age faunal species. If so, it is conceivable that the human populace decrease proposed by the drop in post-Clovis shot focuses over a great part of the Southeast is identified with such a calamitous occasion.
