Lower Carboniferous sponges from the Craven Reef Belt of North Yorkshire
Bibliographic record
Abstract
SUMMARY Fossil sponges are significant elements in framework facies of Late Visean Cracoean reefs of northern England. In the Craven Reef Belt (North Yorkshire), lithistid demosponges, including Scheiia castletonense (Wolfenden 1959), Haplistion carbonaria (Wolfenden 1959) and Haplistion mega sp. nov., occur along with the less abundant, sphinctozoid demosponge Sollasia ramosa sp. nov. in this facies. Scheiia castletonense is an irregular globose to mound-shaped tricranocladinid hindiid sponge with irregular secondary branchlike growths in which the canal and skeletal structure are continuous with those of the globular part of the sponge. Both species of Haplistion are rhizomorinid lithistid sponges. Haplistion mega is a lobate sponge characterized by moderately coarse skeletal tracts that are relatively far apart, in contrast to the fine tracts and closer spacing in the more common globose to subspherical Haplistion carbonaria . The aporate ‘sphinctozoan’ Sollasia ramosa, commonly appears in the available sections as isolated spherical chambers because of its relatively loose branching habit and the beadlike to moniliform series of spherical chambers in each branch.

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.
