Abstract

fetched live from OpenAlex

Bryozoan skeletons are a dominant constituent of cool-wa-ter carbonate sediments in the Cenozoic of southern Austra-lia. The primary substrate on much of the modern continen-tal shelf is loose sediment that is reworked intermittently to 200 m water depth by storm waves. Availability of stable substrate is a limiting factor in the modern distribution of bryozoans in this setting. As a result, a significant propor-tion of the sedimentologically important modern bryozoans (30–250 m water depth) live attached to sessile, benthic in-vertebrate hosts that possess organic or spicular skeletons. Hosts such as hydroids, ascidian tunicates, sponges, soft worm tubes, octocorals, and other lightly-calcified and ar-ticulated bryozoans provide ephemeral substrates; after death, host skeletons disarticulate and decay, leaving little or no body fossil record. The calcareous sediments produced by these epizoic bryo-zoans from ephemeral substrates result in loose particles that rarely preserve substratal relationships, but potential-ly retain diagnostic basal attachment morphologies. Al-though the best known examples of epizoic carbonate pro-duction on ephemeral substrates are from the southern Aus-tralian margin, this may be an important phenomenon both globally and in the fossil record. Bryozoan sediment production from epizoans on ephemeral substrates would seem, however, to have a scant record prior to the Creta-ceous.

Full frame distilled prediction

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.
