Abstract
ABSTRACT A large collection of fishes from Tanzania, East Africa, includes representatives of four or five families of fishes. The majority of specimens are cichlids, with at least five species being represented, distinguished by osteological characters such as the shape of the opercular bones, frontals, and supraoccipital crest. These species are all named and described in the same genus based on shared scale and squamation characters. The site, at Mahenge in the Singida Region, was a crater lake about half a kilometer in diameter. It has been dated as Eocene, about 46 Ma, based on radiometric techniques. The cichlid species, being very closely related, may have constituted a species flock, which would indicate that cichlids had the ability to form flocks as early as the Eocene.

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 it
