Dating the Late Archaic at the Davidson Site (AhHk-54), Ontario
Bibliographic record
Abstract
Abstract A large series of 56 AMS dates are reported from the Davidson site, occupied during both the Broadpoint and Smallpoint Late Archaic. The focus is on documenting the occupation history of the site itself. The dates on various features often do not match superposition data or associations with diagnostics and provide a case study of the great potential for component mixing on such sites, which can go unrecognized without multiple dates from different materials. Despite that evidence, overall the kernel density function models show that the dates fall into two more-or-less distinctive groupings centered at circa 2250 cal BC and at circa 1150 cal BC, matching previous age estimates of the two main components and also suggesting an intriguing circa 300-year gap between those two intensive occupations. The analyses suggest charcoal dates overestimate age when compared to dates from nutshell by about 120 years and that the consistency of dates from particular feature clusters often indicates they represent an “integrated series of events.”

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
