Polymerolepis KARATAJUTE-TALIMAA 1968
Bibliographic record
Abstract
POLYMEROLEPIS KARATAJŪTĖ-TALIMAA, 1968 Type species — Polymerolepis whitei Karatajūtė-Talimaa, 1968. POLYMEROLEPIS SP. (FIG. 6D; TABLE 1; SUPPL. 1, FIGS. 5, 7, 11, 14) Referred specimens —Very rare, one scale at level 458.67’ (139.8 m) and possible scale fragments from 430.5’ (131.2 m), 453’ (138.1 m), 492.3’ (150.1 m): Roberts Mountains Formation. Description and comparison —The scales and scale fragments have finely noded ridges. The scale base is always flat or concave. The type material of P.whitei from the Lochkovian of Podolia shows a wide range of scale morphotypes (e.g., Obruchev and Karatajūtė-Talimaa 1967, pl. 2 figs. 1–4, Karatajūtė-Talimaa 1998, figs. 6, 7). Hanke et al. (2013, figs. 1–5) demonstrated in their description of a partial articulated specimen from the Lochkovian MOTH locality in the Northwest Territories, Canada assigned to P. whitei, comprising an anal fin and part of the caudal fin and peduncle, that the scale variation over the body is even greater than seen in the type scales. Specimens referred to P. whitei from the younger Lochkovian (delta conodont Zone) Windmill Limestone, Simpson Park Range, Nevada include head, fin, and body scales (Turner and Murphy 1988, table 1, figs. 2.14, 15, 20, 22–26). The Nevadan scales are the first record in the Silurian for this taxon. Given the morphological variation in scales from the known localities, it seems possible that more than one species is represented, so we only refer the BC II specimens to an open taxon within the genus rather than to the type species.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
