An Integrated isotopic study of Early Intermediate Period camelid husbandry in the Santa Valley, Perú
Bibliographic record
Abstract
Stable carbon and nitrogen isotope compositions were determined for camelid bone collagen, hair, and wool (fibre) sampled from textiles from archaeological sites in the Santa Valley (north coast of Perú) occupied during Moche III (El Castillo, A.D. 300−500) and Moche IV (Guadalupito, A.D. 500−700) phases; a small number of camelid bone collagen samples were also analysed from the Late Suchimancillo Phase (A.D. 0−300). These data suggest that localised camelid husbandry was practiced in the Santa Valley from at least the Moche III phase. The nature of camelid husbandry likely involved animals being kept spatially segregated and fed a diverse range of fodder. The isotopic compositions of the bone collagen and wool textiles were very similar, which suggests that the wool that was used to produce the textiles was derived from local camelids rather than being acquired from the highlands. The transition from Moche III to Moche IV, which saw a significant increase in Mochica presence in the Santa Valley, was not accompanied by major changes in camelid husbandry practices. Localised camelid husbandry continued through this transition with minimal change; the prolonged droughts of the sixth century A.D. had no discernable effect on camelid husbandry, probably due to the special hydraulic conditions unique to the Santa Valley.

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.
