Abstract

fetched live from OpenAlex

A new species representing the genus Synura, S. cronbergiae, is described from two Paleogene maar lakes situated near the Arctic Circle in northern Canada. The new taxon is characterized by long, slender, siliceous scales each bearing a small forward projecting spine, a base plate with evenly spaced pores and a secondary layer consisting of hexagonal chambers. Each chamber encloses a base plate pore, opens dorsally via a small pore, and collectively the chambers fuse to form a continuous secondary layer. Although S. cronbergiae is believed most closely related to species in the Sectio Synura due to the presence of a distal spine and lack of a median keel, scales superficially resemble those from a rare species in the Sectio Petersenianae, Synura longisquama. The potential evolutionary history, in the context of the genus, is discussed.

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.

Not 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.
