Late Ordovician (Sandbian) ostracods from the Ardwell Farm Formation, SW Scotland
Bibliographic record
Abstract
Synopsis The lower part of the Late Ordovician Ardwell Farm Formation of the Girvan district in SW Scotland yields a low-diversity ostracod fauna comprising six species. Many of these ostracods are biostratigraphically short-ranging North American taxa limited to an interval equivalent to the gracilis and bicornis graptolite biozones. These species include ‘ Ctenobolbina ’ ventrospinosa and Baltonotella parsispinosa that permit inter-regional correlation with the Sandbian strata of the USA and Arctic Canada. This chain of correlation is also confirmed by chitinozoans, such as Belonechitina hirsuta , that occur with the ostracods in the Ardwell Farm Formation. Although allochthonous and transported by turbidity currents into a deep-water clastic-rich basin, the ostracod fauna of the Ardwell Farm Formation resembles other Ordovician deep-water ostracod biotopes, characterized by podocope ostracods and low species diversity. Alternatively the ostracods might simply have been transported from a carbonate ramp setting.

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.
