Radiocarbon dating of human remains from Navan Fort: their implications for understanding the wider ceremonial complex
Bibliographic record
Abstract
This article presents a series of new radiocarbon dates aimed at resolving long-standing issues about the development of the complex of Navan Fort, Co. Armagh, and its wider context. These include radiocarbon dates for human remains from excavations at Site A, Site B, and from the area of the quarry adjacent to Navan Fort. Iron Age, early medieval and post-medieval dates from these remains complicate previous assessments of the site and its development, but add important new data for Navan and its long-term evolution. In particular, evidence for a funerary dimension to the immediate environs of Navan Fort now seems apparent, while further post-medieval activity within the enclosure of Navan Fort extends the chronology of the complex well into the second millennium AD. A date from a human clavicle recovered during excavations suggests the possibility of formal deposition on the cairn of Site B during the Iron Age, and supports the suggestion that the cairn was a focus of activities for a considerable period prior to the construction of the turf mound of Site B. Together these dates add nuance to our understanding of the complex and its long term development, but also raise many new issues about its medieval and later role.

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.
