<i>Terminonaris</i>(Archosauria: Crocodyliformes): new material from Saskatchewan, Canada, and comments on its phylogenetic relationships
Bibliographic record
Abstract
A newly-discovered skeleton of Terminonaris (=Teleorhinus) robusta (=robustus) from the early Turonian marine deposits of east-central Saskatchewan affords the opportunity for a detailed description of the anatomy of this species and its placement in the context of other known species of this genus. The specific diagnosis of T. robusta and the generic diagnosis of Terminonaris are established. Terminonaris robusta differs from the type species T. browni mainly in size-related features. Teleorhinus mesabiensis Erickson, 1969 is placed into the synonymy of Terminonaris robusta. The genus can be diagnosed by features of the anterior end of the snout, suturai relationships of the bones surrounding the orbit, and the structure of the occiput. A phylogenetic analysis based upon data drawn from the new material suggests that Terminonaris is not a pholidosaurid but is, instead, closely related to Dyrosaurus. This analysis continues to support the hypothesis that long-snouted crocodyliforms of the traditional “mesosuchian grade” form a clade.

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.
