Abstract

fetched live from OpenAlex

Abstract: The analysis of morphological characters exhibited by the earliest ontogenetic stages of Middle Jurassic, Cretaceous and Holocene thecideoid species, together with the application of techniques that reveal the presence of early juvenile morphological characters buried in the shell fabric of adult representatives of the species concerned, reinforce the idea of a development pattern common to thecideoids from the early Middle Jurassic to the present day. Basic and long‐standing differences in the architecture of the brachidial skeleton of thecidellinids and lacazellins may be correlated with the morphology of thecospiroids and indicate that the Thecidellinidae and Thecideidae may have emerged as sister groups as early as the Triassic.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
