Discerning invention/innovation processes in artifact design change: Is it time to rethink drifting attributes
A Simple Experiment Challenges the Inference that Macro-fractures on Chipped-stone Tools are Clear Evidence of High-Velocity Impacts
The paradigmatic assumption that prehistoric chipped stone points primarily functioned as hafted armatures of composite hunting weapons is often tested with replicates that are hafted as armatures. Thus, the tests are whether they make good armatures, not whether they were armatures. This precludes systematic inquiry into possible alternative functions and inferences for these tools. We find the evidence marshalled to prove armature use is often …
The Early Holocene archaeology of Florida: Geospatial approaches to understanding Bolen mobility
Three of the most influential archaeological models in the southeastern US have argued that early foragers organized their lifeways via seasonal movement along major drainage basins; around access to raw material sources, crossing drainage basins; or around group foraging needs, following central place foraging models. We examine the distribution of Early Holocene Bolen sites in Florida in light of these models by combining Florida Master Site Fi…
Southeastern Late Paleo indian through Early Archaic Chronologies
A Typology of Florida Fluted Points Using Landmark-based Geometric Morphometrics
This typology of Florida fluted points was created from 164 images of fluted-point bases using landmark-based geometric morphometrics (LGM). Three highly distinctive types were discriminated using the shapes of the point bases. LGM is a powerful method for discriminating shapes, so paying close attention to analytical details is crucial for meaningful analyses. In archaeology, LGM is in its relative infancy compared to its use in biology, and arc…
The age of the Dalton culture: A Bayesian analysis of the radiocarbon data
Since a radiocarbon chronology of the Dalton culture in the Southeast was first proposed, several new sites have been dated. I propose a new chronology based on radiocarbon dates from sites in the Dalton Heartland and its eastern periphery using Bayesian statistical models in OxCal and an analysis of the associated diagnostic projectile points. The analyses indicate that the Dalton culture probably evolved from the Clovis or Gainey phenomena abou…
Dust Cave Revisited: A Bayesian Reanalysis of the Radiocarbon Record
The Dust Cave cultural chronology and radiocarbon sequence is one of the most important in southeastern North America. In their initial interpretation, the excavators were unable to separate the dates of the early and later strata in ways that facilitate their use for defining the associated cultural components. Here the sequence is reevaluated using Bayesian statistics, one additional date, and assessment of potential outliers. The results produ…
The Role of Nondeclarative Memory Systems in the Inference of Long-Term Population Continuity
Discriminating Paleoindian point types from Florida using landmark geometric morphometrics
Subterranean transport and deposition of quartz by ants in sandy sites relevant to age overestimation in optical luminescence dating
Freshwater availability as the constraining factor in the Middle Paleoindian occupation of North‐Central Florida
The locations of reliable surface water exposures during the Middle Paleoindian period (10,800–10,200 14 C yr B.P.) in north‐central Florida are reconstructed and compared to the concentrations of Middle Paleoindian projectile points. Estimates of water table levels and surface water flow in Florida's karst geology confirm prior climate reconstructions for that time indicating the area was arid and supported a xeric ecology in most upland locales…
