Fossils of the Middle Cambrian Burgess Shale, British Columbia, Canada: distribution and biostratinomic change through time
Bibliographic record
Abstract
Over 30 years of commercial hydrocarbon drilling exploration on the Canadian Atlantic Margin has provided the Geological Survey of Canada (GSC) with a priceless collection of micropaleontological samples and data from the thick Jurassic-Quaternary sedimentary wedge underlying our continental margin. This material has allowed a small cadre of GSC scientists and technicians to document and correlate, using standardized methods of preparation and study, the micropaleontological assemblages found in the offshore wells. There has also developed a better understanding of the evolutionary history of individual microfossil taxa and whole benthic assemblages, as well as regional correlations with other microfossil groups. Such studies have helped unravel the tectonic and sedimentary history of the economically important hydrocarbon basins in the region. The state of micropaleontological knowledge of Canadian Atlantic Margin wells, including lists of wells sampled and studied is described, and a comprehensive listing of GSC produced literature on the subject is provided.
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.
