Silurian crinoids of the New Brunswick Museum, Saint John, Canada
Bibliographic record
Abstract
The New Brunswick Museum’s collection of Silurian crinoids from eastern Canada is small, and includes specimens from New Brunswick, Quebec and Nova Scotia. Material considered herein is, with one exception, from New Brunswick. Included are: the cladid Syndetocrinus dartae (Upper Silurian of Quebec); the camerates Scyphocrinites sp. (Pridoli or Lochkovian) and camerate crinoid arms gen. et sp. indet. (Lower Silurian); columnal morphotaxa Floricrinus (col.) sp. (Ludlow or Pridoli) and Lanxocolumnus (col.) sp. cf. L. chaleurensis Donovan and Keighley (probably Llandovery, Telychian); distal dendritic radicular attachments (Ludlow or Pridoli); and disarticulated brachials (Ludlow or Pridoli). ἀe fossil record of crinoids from the Silurian of New Brunswick appears depauperate, but this most likely reḀects the poor preservation of the specimens (commonly disarticulated and moldic) and the lack of interest shown by collectors. ἀe only remedy for this problem would be either discovery of a crinoid Lagerstätte, which would be attractive to collectors, or a focused campaign of collecting of disarticulated material from multiple outcrops.
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.
