Abstract

fetched live from OpenAlex

A new specimen of Dracochelys bicuspis documents the lower jaws and postcranial skeleton of this taxon. A close relationship with Hangaiemys is supported by the presence of nine neural bones, with the sulcus between the fourth and fifth vertebral scute crossing the ninth neural. The two taxa differ in the contacts of the first peripheral, shape of the vertebral scutes, and pattern of fenestration of the plastron. Dracochelys differs from "Sinemys" wuerhoensis and "S. " efremovi, which also occur in the Tugulu Group, in features of the carapace, especially the arrangement of the posterior neurals and suprapygals.

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.
