New occurrence of Ostracodes used as indications of paleoecology and age for Scots Bay Formation, Bay of Fundy, Canada
Bibliographic record
Abstract
Fossils in the Jurassic Scots Bay Formation are rare but silicified, speciesinclude ostracodes, small gastropods, small clams, fragments of charophyte stems, andfreshwater stromatolites. The silicified ostracodes and algae are found in thin to thickbeds of mixed carbonate and siliciclastic units deposited in erosional paleotopographiclows on the top of the Early Jurassic North Mountain Basalt (NMB).Ostracodes are the most common type of fossil in the Scots Bay Formation, in thisstudy nearly 800 specimens have been extracted. These ostracodes are moderately towell preserved, thin-shelled, and occur as whole silicified carapaces, separated valves,and internal molds. Three ostracodes genera have been identified: Darwinula, Timiriasevia, and Metacypris. Determining the exact age for this Formation has been a matter of mild dispute. Therecorded new occurrence of these ostracodes assemblage will help to revise age andprovide enough knowledge about paleoecology of Scots Bay Formation.

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.
