Abstract
Abstract Recent re-evaluation of variation in the carotid circulation of turtles has revealed that the phylogenetic signal contained in this character complex may indicate different patterns of relationship than have previously been hypothesized. Herein we document cranial circulatory development in Apalone spp. and Chrysemys picta for the first time, with the objective of stimulating future, intensive study of the source of observed circulatory variation in turtles. Both species studied exhibit a nearly identical circulatory pattern, resembling that of adult Trionychia, in later developmental stages. This is an unexpected finding given their highly divergent adult conditions. Further study is required to elucidate the means by which the adult circulatory pattern is attained in these taxa.

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
