REVISITING THE TEOTIHUACAN CONNECTION AT ALTUN HA
Bibliographic record
Abstract
An analysis of oxygen-isotope ratios in skeletal phosphate was used to assess the possibility that the Early Classic period (a.d. 280–550) Maya elite male in Tomb F/8-1 from the eastern Belizean site of Altun Ha had originally come from Teotihuacan, Mexico. When compared with four other individuals used as controls for spatial and temporal variability in δ18Op values at Altun Ha, this individual falls at the high end of the expected range of local intrasite variation but does not have a δ18Op value consistent with that of Teotihuacan. The mortuary and isotopic data have been compared with those from the previously analyzed Maya site of Kaminaljuyu, Guatemala, in order to examine regional and temporal differences in the influence of the powerful state of Teotihuacan. It appears that Teotihuacan was not the homeland of any of the tomb individuals analyzed from either site. Thus, models of ideological or symbolic power are supported over those of political or military imperialism.

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.
