As one of six occurrences of this fauna world-wide, it supports the premise that many elements in the Haplotaeniatum Assemblage have a wide geographic distribution and will be of significance in building an Early Silurian radiolarian biostratigraphic scheme with global application. In addition to Haplotaeniatum, this fauna contains palaeoscenidiid and secuicollactine taxa that are known only from one other locality, the Cape Phillips Formation, Canadian Arctic. These taxa may prove to be fairly cosmopolitan and biostratigraphically useful as more data from other localities are collected. Two new genera, Labyrinthosphaera and Gyrosphaera, and three new species, Labyrinthosphaera macdonaldi, Gyrosphaera siljanensis, and Gyrosphaera raneatela, are described herein. Labyrinthosphaera has a multi-layered labyrinthine meshwork and with six or more tri-bladed spines. Gyrosphaera has a labyrinthine meshwork and displays spiraliform layering, similar to that described in Haplotaeniatum, indicating a close phylogenetic link between these two Llandoverian taxa. Further data from additional localities is needed to determine the potential diachroneity of a global Haplotaeniatum acme zone, and to identify additional taxa whose first and last occurrences may be used as biostratigraphic datums for the Llandoverian.

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.
