The Cisuralian Ammonoid Genus <i>Uraloceras</i>
Bibliographic record
Abstract
Ammonoids occur abundantly within Cisuralian strata at Beck Springs, Buck Mountain, Nevada. The genus Uraloceras has been recovered from a micritic concretionary interval deposited within a tectonically initiated sub-basin of the Cisuralian Dry Mountain Trough. The abundant and diverse fauna at Beck Springs, Buck Mountain contain faunal elements characteristic of a transitional paleobiogeographic association, which includes "Boreal", equatorial, cosmopolitan, and endemic forms. Endemism may have been associated with paleogeographic isolation of basins and sub-basins on the western margin of Northern Pangaea.\nUraloceras is biostratigraphically restricted to Sakmarian through early Kungurian of northern Pangaea and further restricted to Artinskian strata in North America. Uraloceras is also an important paleobiogeographic indicator because it is restricted to "Boreal" and "Transitional" associations along the continental margins of Northern Pangaea. The genus Uraloceras occurs throughout Northern Pangaea: the Ural Mountains, Novaya Zemlya, the Verkhoyansk Mountains, China (Nei Monggol and Gansu), Ellesmere Island, the Yukon, British Columbia, Alaska, and Nevada. Four representatives of Uraloceras are recognized in this study; U involutum, U burtiense, U fedorowi, U n. sp. A.

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.
