Abstract

fetched live from OpenAlex

Cyamodontoidea is an armoured lineage of Placodontia, the basal-most clade of Sauropterygia. It was unknown in China until Sinocyamodus xinpuensis was reported in 2000, on the basis of a subadult specimen. Here we describe the first adult specimen of this taxon. This nearly complete specimen was determined to be S. xinpuensis by the stout triangular skull with a short snout, the nasal–nasal contact, a carapace with three types of osteoderms developing rows in meridional ridges and vaulted zones on both sides and the phalangeal formula of 2-3-4-4-2. In this study, the diagnosis of S. xinpuensis is revised based on the new specimen, and the morphological interpretation, especially of the postcranial anatomy, is given. With new information from the adult specimen, our phylogenetic analysis supports the sister-group relationship of Sinocyamodus to Cyamodus. The differences between this new adult specimen and the subadult type specimen reveal ontogenetic variations in morphology, such as the growth of the posterior portion of the skull, the number of osteoderms and the configuration of the carapace.

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.
