Cranial and postcranial anatomy of<i>Cacops morrisi</i>, a eucacopine dissorophid from the early Permian of Oklahoma
Bibliographic record
Abstract
The armored dissorophid Cacops morrisi is one of many anamniote taxa preserved at the speciose early Permian karst deposit near Richards Spur, Oklahoma. The taxon was previously known only from two isolated skulls representing a juvenile individual and an adult individual. Here we describe one partial and two complete new skulls of juvenile and subadult individuals of C. morrisi that represent intermediately sized individuals compared with previously documented skulls, as well as the first description of the postcrania of the taxon. The primary objectives of this paper are to expand upon the brief original description of the cranial material and to provide the first description of the postcrania of C. morrisi for comparison with other dissorophids. The new data improve the resolution of the ontogenetic series of the taxon through refined temporal constraints on major ontogenetic changes of the cranial region (e.g., closure of the otic notch, transition in lateral skull profile), contribute new information regarding the neurocranium, and improve our understanding of dissorophid postcrania. We also identify several new diagnostic features, such as the presence of uncinate processes on the ribs (previously unknown in the genus) and the exclusion of the lacrimal from the orbital margin (unique among dissorophids).Citation for this article: Gee, B.

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.
