Tel Tsaf and the Impact of the Ubaid Culture on the Southern Levant: Interpreting the Radiocarbon Evidence
Bibliographic record
Abstract
A data set of 18 radiocarbon dates from the domestic quarter and the well at Tel Tsaf provide conclusive evidence for the absolute dating of this Middle Chalcolithic site. Bayesian modeling suggests that the site was occupied in the last quarter of the 6th millennium BC and abandoned in the first quarter of the 5th millennium. The absolute dating of Tel Tsaf has further implications for the synchronization of the protohistory of the Levant. The ceramic assemblage of Tel Tsaf included delicately painted ceramic sherds (so-called Tel Tsaf ware), which are distinct from the common plain ware. Comparable motifs have been identified in ceramic assemblages of contemporary Ubaid sites such as Tell Mashnaqa, Tell Zeidan, Tell el-Abr, and Hammam et-Turkan IV in northern Mesopotamia. Tel Tsaf is a rare example of a little researched connection between the Ubaid culture and the Middle Chalcolithic of the southern Levant. The findings of Tel Tsaf expand the southwestern border of the Ubaid sphere of influence and shed new light on long-distance interaction in protohistory. DOI: 10.2458/azu_rc.57.18200

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.
