A new parareptile (Parareptilia, Lanthanosuchoidea) from the Early Permian of Oklahoma
Bibliographic record
Abstract
ABSTRACT An exquisitely preserved skull of Feeserpeton oklahomensis, gen. et sp. nov., collected from the Lower Permian fissure-fill deposits near Richards Spur, Oklahoma, is the newest parareptile from the locality. The specimen comprises an almost complete skull, lacking most of the premaxillae, parts of the jugals, and parts of the braincase. The maxillae and dentaries possess caniniform regions, including large caniniform teeth that are at least twice as large as any other tooth in the jaws. A phylogenetic analysis of Parareptilia that includes the new taxon indicates that the Early Permian F. oklahomensis is a member of the poorly known Lanthanosuchoidea, positioning it as the sister taxon of a clade consisting of Acleistorhinus pteroticus and Lanthanosuchus watsoni. This new taxon adds significantly to our limited knowledge of the early stages of parareptile evolution, as well as the large terrestrial tetrapod diversity found at Richards Spur.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
