Some Early Pragian Brachiopods from Soda Creek Limestone of West-Central Alaska
Bibliographic record
Abstract
Abstract The brachiopod taxa Schizophoria (Paraschizophoria) protonevadensis Smith, 1980, Plicogypa kayseri alaskensis subsp. nov., subfamily Rzhonsnitskayaellinae subfam. nov., Rzhonsnitskayaella gen. nov., Rzhonsnitskayaella lata sp. nov., Protathyris amsdeni sp. nov., and Nucleospira hecetensis Kirk and Amsden, 1952, are described and illustrated from the Soda Creek Limestone (Early Pragian) of west-central Alaska. These provide a significant increase of Pragian brachiopod taxa described to date from Alaska. The brachiopods described here are the same species or similar to species found in the basal Heceta Limestone of southeast Alaska (Plicogypa kayseri Peetz and Nucleospira hecetensis Kirk and Amsden) and in the Canadian Arctic Islands Schizophoria (Paraschizophoria) protonevadansis Smith, 1980).

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.
