Dianulites rocklandensis Wilson 1921
Bibliographic record
Abstract
Dianulites rocklandensis Wilson, 1921 (Figs 5 F-G; 6A; Appendix 1) Dianulites rocklandensis Wilson, 1921: 47, pl. 2, figs 1-2. MATERIAL EXAMINED. — Single colony (three thin sections) CEGH-UNC 27503 a-c. OCCURRENCE. — La Pola Formation, Upper Ordovician, Sandbian; La Pola creek section near Albardon village, San Juan Province, Argentine Precordillera, western Argentina. Leray and Rockland formations, Upper Ordovician (Sandbian); Canada. DESCRIPTION Massive hemispherical colony, 8.5 mm thick in its central part and 20 mm wide at its base. Secondary overgrowth not observed. Exozone indistinct. Autozooecia long, prismatic, growing from epitheca. Autozooecial apertures polygonal. Diaphragms straight, rare to common in endozone, common in exozone. Autozooecial walls indistinctly granular, irregularly thickened, 0.015 -0.040 mm thick. Maculae not observed. COMPARISON The present material is similar to Dianulites rocklandensis Wilson, 1921 from the Ordovician (upper Sandbian) of Canada. This species, as described byWilson (1921), developed branched ramose colonies. However, Kang (2017) mentioned also hemispheric colonies of this species found at the type locality. Dianulites rocklandensis differs from D. microcellatus Astrova, 1945 from the Upper Ordovician of Urals in larger autozooecial apertures (0.24-0.36 mm vs 0.19-0.28 mm in D. microcellatus).
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.
