Abstract

fetched live from OpenAlex

A rich fossil assemblage discovered from the classic Pennsylvanian locality of Joggins, Nova Scotia, is here described for the first time. The 2 m-thick Hebert sandstone, within the lower Joggins Formation of early Langsettian age, is the most productive stratum at Joggins of terrestrial tetrapods and the pulmonate gastropod Dendropupa vetusta exclusive of the historic fossil forest locality of Dawson and Lyell, and the most productive Pennsylvanian locality in the world of the large unionoid bivalve genus Archanodon. Although the land snail–archanodontid bivalve–tetrapod assemblage of the Hebert Sandstone comprises a unique late Paleozoic terrestrial dryland biota, individual taxa were not endemic to drylands alone.

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.
