Abstract

fetched live from OpenAlex

Recently, two partial skeletons of an archosaur have been collected from the upper part of the Triassic Ermaying Formation in Shanxi Province, China, which represent a new pseudosuchian, Taihangosuchus wuxiangensis gen. et sp. nov. The new species can be diagnosed based on a set of cranial and postcranial characteristic states and assigned to Gracilisuchidae. Our phylogenetic study finds that T. wuxiangensis gen. et sp. nov. is the second most basally branching gracilisuchid and that Gracilisuchidae and Erpetosuchidae are nested together as the most basally branching clade of Pseudosuchia, implying that Gracilisuchidae diverged within a sub-clade rather than directly from the mainline of Pseudosuchia. Furthermore, Aetosauria and Ornithosuchidae form a clade at the base of Suchia. Phylogenetic patterns recovered in this study for the four basally branching clades of Pseudosuchia and the members of Gracilisuchidae are congruent with their chronostratigraphies better than those obtained in previous studies.LSID: urn:lsid:zoobank.org:pub:2877A471-DB2E-42B2-BC72-923640CB747ELSID: urn:lsid:zoobank.org:act:82AC5B04-2D10-45C7-AB5D-CD3277A39038

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.
