Bibliographic record
Abstract
Genus Paradysagrion gen. nov. ZooBank Registration number: rn:lsid:zoobank.org:act: 9540B488-96D6-4697-BCCE-82C7BAE16E10 Figure 2 Diagnosis. Preserved wing portion most similar to that of Dysagrion Scudder by: pterostigma about 6.3 times longer than wide [Dysagrion species: 4.0–7.5]; many intercalated linear (or nearly so) supplementary sectors between main veins from RP1 to probably CuA (see below; cf. figures of Archibald et al. 2021, cited below); IR1 linear from origin as in Dysagrion fredericii Scudder (see Archibald et al. 2021, fig. 6), slightly zigzagged in Dysagrion pruettae Archibald and Cannings (see Archibald et al. 2021, figs. 17–18) and Dysagrion lakesii Scudder (see Archibald et al. 2021, fig. 5), fully zigzagged in Dysagrion packardii Scudder (see Archibald et al. 2021, fig. 4). It differs from wings of Dysagrion by: (1) RA, RP1, IR1 subparallel to apex, apex between terminus of RA, RP1 [Dysagrion: converging at apex, RA at or near apex]; (2) CuA (presumed, see below) linear to termination [Dysagrion: heavily zigzagged]; (3) no brace vein [present in D. pruettae; region poorly or not preserved in other species]; (4) RA–RP1 space between pterostigma and apex three cells wide in most of distal half, seven at margin [Dysagrion: one]; (5) C–RA space distal to pterostigma two cells wide [Dysagrion: one]; (6) RP1, IR1, and RP2 spaces, each with two linear supplementary sectors, terminate with similar widths [Dysagrion: without supplementary sectors, and RP1, IR1 terminate very close, IR1, RP2 not]; and (7) subnodus distinctly angled with normal obliquity [Dysagrion: reverse obliquity]. Description. As for its only species, below. Etymology. The genus name is formed from the Greek -para, “alongside,” and Dysagrion, referring to similarities of its wings to those of that genus. Gender, neuter. Remarks. Dysagrion (cf. Archibald et al. 2021, figs. 4–6, 16–18) is also known from exposure B4131 of the Klondike Mountain Formation. Its most similar species, D. fredericii, is from the Green River Formation of Wyoming, also in the latter portion of the Ypresian.
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.
