An Corran, Staffin, Skye: a rockshelter with Mesolithic and later occupation
Bibliographic record
Abstract
The An Corran rockshelter, on the north-east coast of the Trotternish peninsula, Skye, contained a series of shell midden and other deposits with evidence for human occupation from Mesolithic and later periods. A rescue investigation of the site in the winter of 1993-94, immediately prior to anticipated total destruction by rock-blasting for roadworks, included the excavation of a trench dug down to bedrock. A total of 41 separate contexts were identi-fied. Of these, 31 were recent or later prehistoric, the upper levels containing a series of hearths of recent date and an Iron Age copper-alloy pin. The lowest 10 layers were identified initially as Mesolithic on the basis of bone tool and lithic typology, but a series of 18 radiocarbon dates indicates they contain the residues of subsequent prehistoric activity as well. These layers consisted of several distinct areas of midden, below which there were two, possibly three, horizons which probably, based on the presence of broad blade microliths, represent Early Mesolithic activity. The midden layers also contained some human bones radiocarbon-dated to the Neolithic period. The rockshelter was located below an outcrop of baked mudstone and near a source of chalcedonic silica. Both these lithic raw materials were widely used during the Mesolithic as far away as the island of Rum.

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.
