Late Miocene and Pliocene pikeperches (Teleostei, Percidae) of southeastern Europe
Bibliographic record
Abstract
Freshwater fish fossils representing two or more species of Sander (S. lucioperca, S. svetovidovi, and Sander sp.) and Leobergia zaissanica are reported from a number of localities in Southeastern Europe. These localities sample the late Miocene through early Pliocene, when the landscape was undergoing major changes associated with the collision of the Afro-Arabian and Eurasian plate. This caused changes to ocean circulation with the closing of the Tethys, as well as uplift of mountain ranges in Europe. This was also a period of significant climate change, with the onset of polar glaciation causing a cooling, drying phase globally but also specifically documented for this region. The fossil fish material documents the presence of percids during this time and also the apparent loss of Leobergia in the Pliocene. The loss of Leobergia may well have been caused by a lower tolerance to cool climates of this genus compared to Sander, a genus with five extant species.Citation for this article: Kovalchuk, O.

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.
