Abstract
Abstract Three-dimensionally preserved specimens of the problematic Early Cambrian fossil Salterella are described from acid-resistant residues of limestone samples from the Lower Cambrian Forteau Formation of western Newfoundland. The material exhibits three disparate modes of preservation, complementing the prevailing description of the fossil in the literature from thin-sections. Juvenile specimens of Salterella with the external shell surface replaced by silica show a pronounced ornamentation of transverse annulations. Other specimens are preserved either by infilling of the apertural cavity by diagenetic phosphate, or replacement by silica of originally calcareous shell material. Replacement by silica of the internal lining of the apertural cavity, and infilling of the apertural cavity by secondary phosphate reveal a high degree of variability of the internal morphology of the apertural region of the fossil.

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
