Abstract

fetched live from OpenAlex

ABSTRACT A new elasmosaur, Terminonatator ponteixensis, gen. et sp. nov., from the Upper Campanian Bearpaw Formation of southwestern Saskatchewan, Canada, is one of the youngest plesiosaurs from the Western Interior, and one of the few plesiosaurs for which detailed osteology of both skull and postcrania is available. The skull includes the upper side of the inner ear cavity and a median portion of the roof of the braincase. This taxon is distinguished from other elasmosaurs by a combination of several osteological characters variable among elasmosaurs, as well as the unique feature of a high and pointed coronoid process. Anomalous ossification is seen in the fused or pronged gastralia, development of tubercules in metacarpale, and healed fracture of the limb. The dorsal portion of the braincase is compared with other plesiosaurs, showing a variation in plesiosaur braincase morphology. Identity of carpal and tarsal elements is examined based on recent debates on the homology of mesopodials.

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 distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
