AN EARLY WOODLAND DOMESTICATED CHENOPOD (<i>CHENOPODIUM BERLANDIERI</i>SUBSP.<i>JONESIANUM</i>) CACHE FROM THE TUTELA HEIGHTS SITE, ONTARIO, CANADA
Bibliographic record
Abstract
A cache of charred, domesticated chenopod ( Chenopodium berlandieri subsp. jonesianum ) seeds is reported from the Early Woodland (930–915 cal BC) Tutela Heights site (AgHb-446) in Brantford, Ontario, Canada. This is the northernmost report of the crop, approximately 800 km northeast of Kentucky where the previous northernmost occurrences contemporary with Tutela Heights are reported. The Tutela Heights chenopod dates to about 1,500 years before the earliest maize is reported in Ontario and is the earliest Eastern Agricultural Complex crop in Canada. The chenopod may represent a crop that was not grown locally. In this scenario, the crop was strictly an exchange item that was circulating in an interregional exchange system that extended south to the US Midwest region and east to the Maritime provinces. Another possibility, although less likely given our current understanding of Early Woodland plant use in Ontario, is that chenopod was introduced to Southern Ontario in this exchange network and subsequently became a crop in a low-level food producing economy during the Ontario Early Woodland. However, no ecological indicators of cultivation have been found at Tutela Heights, and continuity of domesticated chenopod utilization from the Early Woodland period in the province has not yet been documented.

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.
