Peyssonnelid Rhodoliths from the Late Pleistocene Ironshore Formation, Grand Cayman, British West Indies
Bibliographic record
Abstract
Abstract Rhodoliths from the Late Pleistocene Ironshore Formation in the Crystal Harbour area on the western part of Grand Cayman, which are up to 14 cm long, are characterized by thick cortices that were constructed around nucleii formed primarily of coral or bivalve fragments. Two different communities of encrusting organisms constructed the cortices. The thin inner zone (average ∼2 mm thick) was formed by the Coralline Community which was dominated by Lithoporella, Lithophyllum and Neogoniolithon, along with fewer Peyssonnelia rubra, Hydrolithon reinholdi, Lithothamnium, and Porolithon. The thick outer zone (up to 60 mm thick) is dominated by Peyssonnelia rubra, along with scattered coralline algae, serpulid worms, foraminifera, and bivalves. The Cayman rhodoliths grew in narrow zones surrounding large patch reefs that developed in water less than 14 m deep. The sciaphyllic Peyssonnelia rubra may have grown beneath a non-calcareous fleshy alga that covered the encrusting organisms. The change from the ...

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; both teacher heads agree on what is shown here.
