CHRONOLOGY OF THE ARCHAEOLOGICAL SITE OF PLAYA DEL MANGO, RIO CAUTO, GRANMA, CUBA
Bibliographic record
Abstract
ABSTRACT Fewer than 200 radiocarbon ( 14 C) dates with secure contextual information are available for Cuba, making it challenging to reconstruct Caribbean indigenous population dynamics, their identities and interactions. In this paper, we discussed 21 accelerator mass spectrometry (AMS) 14 C dates from two mounds (M1 and M2) at the Playa del Mango site (Granma province, Cuba), traditionally associated with the Banwaroid stone tool tradition. The ΔR calculated for the site was –132.0 ± 176 and –164.0 ± 68. The chronology of burials from the peripheral area of M2 suggested that the cemetery was continuously used from at least cal BC 116–AD 241 (2 σ). The domestic area of M2 was used at minimum between cal BC 55–AD 435 (2 σ), which encompasses the use of the funerary areas. An isolated human tooth from M1 [cal AD 125–435 (2 σ)] suggested that this funerary area is later than the one at the periphery of M2, and possibly contemporaneous with the later formation of the M2 shell midden. The archaeological assemblage of the “Banwaroid tradition” is widely distributed in Cuba, and mixed with other archaeological traditions, supporting that a complex web of human interactions took place in the Caribbean in precolonial times.

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.
