Abstract
Chengjiang is one of several Cambrian sites, including the celebrated Burgess Shale of Canada, which preserves an abundance of important soft-bodied fossils. The Chengjiang Lagerstätte contains by far the most diverse and disparate fauna – paleocommunity – known from the lower Cambrian, although there are other lower Cambrian sites that have additional taxa with soft-tissue preservation and therefore contribute to the total story of global early Cambrian biodiversity. Other important fossil Lagerstätten from the Cambrian include, for example, Sirius Passet in North Greenland, the Emu Bay Shale of Australia, and fossils of Orsten-type preservation originally described from material from Sweden. Fossils of Orsten-type were discovered by Klaus Müller in the mid-1970s by laboratory preparation of limestone nodules from the late Cambrian bituminous Alum Shales of southern Sweden. The fossils preserve soft tissues and hard parts but the mode of preservation appears to have captured only cuticle-bearing metazoans, especially arthropods and also cycloneuralian nemathelminths.
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 machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
