Abstract
Today’s European sturgeons are relics of erstwhile widely distributed populations, diminished mainly by overfishing and habitat changes over the centuries. While extinct European populations in the Baltic and North seas have been identified as Acipenser oxyrhinchus or A. sturio, a clear species determination on the Iberian Peninsula is still lacking. Plans to conserve existing populations and to re-introduce extinct wild populations in European rivers will benefit from information of historic population/genotype composition. In this study, we used techniques involving ancient DNA as well as morphological comparisons based on bony scutes to identify twelve samples from five archaeological sites (650bc–1500ad, one sample dated 10.1–11.8 ky) on the Iberian Peninsula. All amplified PCR products of bony scutes (n = 5) had the mitochondrial DNA haplotypes of European sturgeon. Neither mitochondrial haplotypes of A. naccarii nor mitochondrial haplotypes of A. oxyrinchus were found.

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 it
