Abstract
The large holasteroid echinoid Hemipneustes striatoradiatus (Leske) was exploited by diverse invertebrate encrusters and borers during the Maastrichtian, both pre- and post-mortem. In life, the specimen described herein was perforated by multiple Oichnus simplex Bromley borings close to the apical system. Each engendered a growth reaction from the echinoid, a mound-like swelling on the external surface of the test with the boring at the centre. These would have been moved away from the apical system as the echinoid grew and inserted new plates apically. Whether this infestation was the product of numerous individual organisms or, less likely, just one organism (gastropod?) that relocated when discouraged by each mound-like swelling is uncertain. Similar growth reactions are known from other echinoderms, but associated with non-penetrative Oichnus paraboloides Bromley.

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
