Isotopic Analyses of The Domestic Animals of Norse Greenland
Bibliographic record
Abstract
To provide a basis for the isotopic dietary study of the Greenland Norse, and as an interesting study in itself, measures of the stable carbon (δ13C) and nitrogen (δ15N) isotope ratios were obtained for 118 samples of archaeological bone from 6 species of the Norse domestic animals. These samples were obtained from museum faunal collections representing archaeological excavations of 10 Norse sites, five in each of the two Norse settlements in Greenland. In general, the carbon isotope values for the herbivores of dietary importance (cattle, sheep, and goats) were as expected for animals living in a C3 environment. The nitrogen isotope data hint at differing field management practices between the two settlements. There is no isotopic evidence for any unusual pastoral adaptation to conditions in Greenland, or for any change in animal management over the lifetime of the settlements. A few pigs form an exception to this statement, but they are peripheral to the Norse dietary economy. These data provide a solid first data set on which to base isotopic dietary analyses of the Norse settlers themselves.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
