Abstract

fetched live from OpenAlex

Colonial rugose corals with a heterocoral-like septal pattern are diverse and common in the Tournaisian–Viséan (Mississippian) of South China. Numerous species were named in classical works but most of them require systematic revision. Newly collected material allowed eight Heterostrotion species to be recognized (ranging from the upper Tournaisian up to the middle Viséan), including a new species H. huaqiaoense; three Stylostrotion species (middle Viséan), including a new species S. houi and four Polygonaria species (upper Tournaisian and upper Viséan). Heterostrotion as the oldest genus of the Stylostrotionidae probably originated in the western Palaeotethys and migrated to South China during the Tournaisian. The development of the cerioid genus Polygonaria from large-sized Heterostrotion during the late Tournaisian is described. The origin of Stylostrotion is however proposed in the evolution of Heterostrotion by a reduction of the minor septa and the development of a columella during the middle Viséan. Stylostrotion is known only from China, where it seems to have evolved by homeomorphy with Siphonodendron, which only occurred in that area in the late Viséan.http://zoobank.org/urn:lsid:zoobank.org:pub:15F3D222-7027-4771-A8B5-05F024D298A0

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.
