Stable isotope evidence for Amerindian subsistence in Newfoundland, 2800 B.C. to A.D. 1829
Bibliographic record
Abstract
Archaeological research has informed on the lifeways of Newfoundland’s past \nAmerindian populations, but their subsistence practices are still poorly understood, \nparticular with respect to the roles played by marine and terrestrial resources. To \ninvestigate Amerindian diet, isotope ratios (δ¹³Ccoll, δ¹⁵Ncoll) were measured in 86 \nskeletons from the Maritime Archaic site of Port au Choix-3 (4500 – 4000 cal B.P.), and \nin 29 skeletons from 12 Recent Indian/Beothuk sites (AD 1000 – 1800). Whole dietary \ncarbon was estimated by measuring carbon isotopes in the enamel of 12 Beothuk \nskeletons. The Maritime Archaic sample was characterized by the presence of at least two \nsubsistence patterns: one marine-based, and the other mixed marine-terrestrial. These \npatterns may relate to geographic origin, or to biosocial categories. Recent \nIndian/Beothuk diet was revealed to be predominantly mixed marine-terrestrial in origin, \nbut characterized by increasing amounts of terrestrial foods in the late historic period.

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.
