Abstract
Abstract Incremental analysis of stable carbon and nitrogen isotopes in tooth dentine is used to explore child and adolescent diet among individuals in the Late Roman Michelet Necropolis (Lisieux, France; fourth to fifth centuries CE). We analyzed 292 incremental sections from 46 second and third molars to explore dietary patterns between the ages of 4.5 and 23.5 years. Results indicate that individuals consumed more, or higher trophic level, terrestrial‐based animal proteins as they aged. Sex‐based comparisons also suggest that males and females consumed isotopically similar diets for most of their childhood; however, around age 16.5, males exhibited significantly lower δ 15 N values than females with a large effect size ( U = 21.0, p = 0.012, g = 1.3). This difference in diet occurs during an important age‐based social change in the Roman life course, as individuals transitioned from childhood ( pueritia ) to adolescence ( adulescentia ). When the isotopic data are combined with literary and archaeological evidence, it suggests that this was the point when men and women diverged in their life course trajectories. Young men were expected to begin apprenticeships or military duty away from home, whereas women were kept close to their family home at this age. The isotopic results suggest these gendered experiences may have influenced dietary choices or access to foods at Lisieux‐Michelet. The results of this study demonstrate the utility of using permanent dentition in adult remains to explore childhood experiences and provide new insights into child and adolescent diet and gendered experiences in the context of the Late Roman Empire.

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
