Lowermost Silurian graptolites from the Kurama Range, eastern Uzbekistan
Bibliographic record
Abstract
An unusually diverse fauna of biserial graptolites has been recovered from the Kajrak and Urubulak formations in the Kurama Range of eastern Uzbekistan. The fauna consists of 26 distinct taxa, 24 of which are systematically described and illustrated. The entire fauna can be assigned to the Akidograptus ascensus–Parakidograptus acuminatus Biozone, which is earliest Rhuddanian (early Llandovery) in age. Within this biozone, however, three regionally distinguishable subzones can be recognized, the N. lubricus, A. cuneatus and H. sinitzini subzones. New taxa described are Normalograptus larini, Normalograptus skeliphrus, “Paraclimacograptus” kiliani kuramaensis, “Glyptograptus” jerini , and “Glyptograptus” ugurensis. New combinations described are Normalograptus acceptus (Koren’ and Mikhaylova, 1980), Normalograptus bicaudatus (Chen and Lin, 1978), Normalograptus jideliensis (Koren’ and Mikhaylova, 1980), Normalograptus lubricus (Chen and Lin, 1978), Normalograptus mirnyensis (Obut and Sobolevskaya, 1967), and Sudburigraptus illustris (Koren’ and Mikhaylova, 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.
