Abstract
A new weigeltaspid heterostracan, Orthogoniaspis amnicus nov. sp. represents the first weigeltaspid reported from the Early Devonian Peel Sound and Snowblind Bay formations, Nunavut, Canadian Arctic. One partially articulated specimen shows for the first time that while the main plates of the dorsal shield abutted each other the orbital, pineal and rostral plates were separated by bands of tesserae. The similarity of this arrangement to that of the corvaspids, particularly the presence of dorsal lateral plates and bands of tesserae separating the anterior plates suggests a sister-group relationship, as no other heterostracans share this arrangement. Arctic weigeltaspids range from the late Ludlow to the late Lochkovian (O. amnicus nov. sp.), which is earlier than the related European taxa suggesting an Arctic centre of development for the weigeltaspids, as has been suggested for other heterostracan 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
