Abstract

fetched live from OpenAlex

Thin sections from the three syntypes of Araucarioxylon arizonicum Knowlton, 1889 were re-examined and found to be anatomically distinct. Two of the syntypes are similar and, considering Araucarioxylon ("Araucaroxylon") Kraus, 1870 as nomen superfluum, those two are placed in Pullisilvaxylon gen. n. as nomen novum (lectotype Pullisilvaxylon arizonicum). The third specimen, known as the 'Sherman log', is transferred to Chinleoxylon knowltonii gen. et sp. n. Permineralized woods in three randomly sampled large-diameter logs assumed to be A. arizonicum plesiotypes were found to be anatomically distinct, two being species within Silicisilvaxylon gen. n., the third named Crystalloxylon imprimacrystallum gen. et sp. n. Thus, following descriptions of Arboramosa semicircumtrachea

Full frame distilled prediction

Teacher imitation

Not 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.
