The new paleontological data contradict older ideas on the Neoproterozoic age of the Walden Creek Group. The Walden Creek Group was not deposited in a continental rift basin preceding the opening of the Iapetus ocean but, possibly, in a pull-apart basin formed in a transtensional event during the Acadian orogeny. There is no field evidence indicating that the Walden Creek Group is separated from the lower units of the Ocoee Supergroup by a basin-wide unconformity and hiatus. A tentative geodynamic model is presented for the Ocoee Supergroup basin; the model is dependent on paleontological data indicating a Paleozoic age for the Walden Creek Group and concentrates on lithologic, petrographic, and basin characteristics. The model allows for the possibility that the entire Ocoee Supergroup was deposited in a Paleozoic transtensional basin.

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
