On <i>Oanducystis</i> (col.) Stukalina (Crinoidea) from the Craighead Limestone Formation, Girvan district, Ayrshire
Bibliographic record
Abstract
Only two nominal species of crinoid, the diplobathrid camerates Diabolocrinus craigheadensis Ramsbottom and Diabolocrinus globularis (Nicholson and Etheridge), have been described from the Ordovician (Chatfieldian; Sandbian) Craighead Limestone Formation, Craighead Quarry, near Girvan, Ayrshire. In contrast, columnal morphotaxa are represented by over 20 taxa including those in open nomenclature. Two thecae from Craighead Quarry and referred to Diabolocrinus sp. or spp. preserve features of the stem facet that are similar to specimens referred to Oanducystis (col.) spp. from the same locality. These columnal morphotaxa are synonymized with Diabolocrinus and left in open nomenclature. However, Diabolocrinus is limited to Laurentia, whereas the remaining morphospecies of Oanducystis (col.) Stukalina are limited to Kazakhstan and Estonia.
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.
