Abstract
Ichnotaxobases that provide internally consistent classification schemes for trace fossils such as burrows and borings include general form, branching, orientation, ornamentation, internal structure and fill, and boundaries. Substrate is a poor ichnotaxobase but it has been widely used for some ichnogenera, most notably the clavate (club-shaped) borings commonly produced by bivalves. The ichnogenus Teredolites Leymerie includes only two ichnospecies, both limited to xylic (woody) substrates; Teredolites clavatus Leymerie, the type species; and Teredolites longissimus Kelly and Bromley. Teredolites clavatus are club-shaped and short, whereas T. longissimus are long and straight to sinuous to worm-like. Although both are (commonly) bivalve borings in wood substrates, they are morphologically highly dissimilar. Teredolites longissimus Kelly and Bromley is made the type ichnospecies of Apectoichnus igen. nov. herein. Apectoichnus includes elongate borings, commonly circular in section, smooth-sided, sinuous to contorted and intertwined, and with or without a calcareous lining; they are found in wood.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
