Paleoamerican Coastal Zone Preference for the Atlantic Slope of Eastern North AmericaUniversity of Tennessee (2013)
This poster presents a coastal model to explain the distribution of Clovis and post Clovis projectile points across the Atlantic slope of Eastern North America relative to coastal zone width. Marine transgression resulting from Melt water pulse 1B has submerged large tracts of the Atlantic continental shelf. Coastal areas with gradual sloping landforms promote superior shallow bays and lagoonal habitats for coastal organisms relative to areas of steeper shelf gradient. Global Bathymetric data was employed to estimate the Clovis age shoreline from Delaware to Florida. Clovis and post Clovis biface data, obtained from the Paleoindian Database of the Americas, (PIDBA) was compared to the slope of the paleo-shoreline to predict coastal zone preference. Areas where major rivers intersect broad coastal zones served important roles to Clovis subsistence adaptations.
