TRYPANITES-TYPE ICHNOFACIES AT THE BAY OF FUNDY, NOVA SCOTIA, CANADA
Bibliographic record
Abstract
Abstract The Trypanites ichnofacies is frequently associated with low biotic and trace diversity, and erosional or nondepositional conditions. However, analysis of an extensively exposed, modern, siliciclastic, intertidal hardground community near Thomas Cove, located at Economy Point, Nova Scotia, within the Bay of Fundy, reveals a diverse community of boring, encrusting, and squatting/clinging organisms and a diverse assemblage of sedimentary structures. A high diversity of biota and low diversity, but high abundance, of borings is present along this modern Trypanites-type ichnofacies. Species richness reaches 37 organisms within the study area, and two boring bivalves (Petricola pholadiformis and Zirfaea pilsbryi), which produce Gastrochaenolites-like traces, are present. Eleven distinct depositional subenvironments are identified and are categorized as being either Trypanites-bearing or Trypanites-barren. Analysis of this modern analogue suggests that ancient Trypanites ichnofacies may have been more dynamic and diverse environments than is sometimes interpreted from the rock record.

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.
