Abstract

fetched live from OpenAlex

Phylogenetic analysis of most species within Necrocarcinoidea based upon 55 adult morphological characters supports the inclusion of 5 families within the superfamily. Two new genera are recognized within Necrocarcinidae, Arcticocarcinus n. gen. and Elektrocarcinus n. gen., and numerous new combinations have resulted. Necrocarcinoidea exhibited diversity peaks in the Albian (Early Cretaceous) and Campanian (Late Cretaceous), and displayed niche partitioning at the family level. Most Paleogene occurrences of Necrocarcinoidea are in carbonate rocks of Northern Europe.

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.
