Pre-Mamom Pottery Producers in the Heart of the Yucatan Peninsula
Bibliographic record
Abstract
Recent research in the Maya Lowlands has revealed substantial new evidence for the first pottery producers at about 1000-600 bc, during the early Middle Preclassic period. This comparatively late adoption is a special case in Mesoamerica, where pottery appeared elsewhere up to a millennium earlier. Although archaic lifeways had long been established in the region, and pottery technology was likely known to some archaic communities, these new data reveal the complex set of circumstances that prompted the shift to ceramic production across the Yucatan Peninsula, Peten, and Belize. This article reviews these data from the perspective of the upland region of central and southern Yucatan, known as the Elevated Interior Region (EIR). Its rather complex early settlement links the EIR to contemporary pottery industries throughout the peninsula, suggesting well-established exchange systems were in place even as the first populations chose to settle more permanently on the landscape. Most significant among these cultural shifts was the increasing dependence on maize foodways as a primary subsistence strategy. Intensive maize agriculture has not been documented in Mesoamerica much before 1000 BC, yet ceramic technology was adopted independent of its use in other areas. Current evidence suggests, however, that the two were linked in the Maya Lowlands, where a relatively rapid transition took place as horticultural communities became more dependent on maize crops, followed waterways to settle more permanently on the landscape, and began producing pottery locally.

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.
