Prod Traces (<i>Selenichnites</i>) from the Middle Cambrian of Morocco, with Hypotheses on the Ethology of the Tracemaker(s)
Bibliographic record
Abstract
A single bedding surface was identified along the roadside close to an important road junction at Tansikht and north of Zagora in southern Morocco. This bedding plane has concomitant interference ripples and distinct horseshoe shaped concave epirelief ichnofossils dispersed across the surface. The sandstone bed belongs to the upper middle Cambrian Azlag Formation. The Azlag Formation occurs above the Bailiella Formation, with its distinctive trilobite fauna, in this section. The traces provide evidence of the ethology of an organism that was inhabiting the shallow waters during this time. Body fossils are rarely preserved in a clastic setting. The traces, assigned to the ichnogenus Selenichnites, and the new ichnospecies, Selenichnites tesiltus, are proposed, identified, diagnosed, described and illustrated herein. Possible tracemakers and behaviors are considered.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
