A Multidisciplinary Palaeoenvironmental Reconstruction of the Campanian Foremost Formation of Southern Alberta
Bibliographic record
Abstract
The Foremost Formation of southern Alberta, Canada, is the basal member of the Cretaceous (Campanian) Belly River Group, and has been understudied relative to the overlying Oldman and Dinosaur Park formations of this group.Examined outcrop of the upper Foremost Formation preserves coastal estuarine or barrier island/lagoonal environments that transition upward into more inland coastal/ fluvial plain environments during the Claggett marine regression of the Western Interior Seaway.A low abundance, low diversity agglutinated benthic foraminiferal fauna, together with whole rock geochemical proxies, suggests commonly stressed oxygen and salinity conditions in marginal marine environments.Vertebrate microsite faunas display a primarily brackish water environmental influence, with an increase in diversity upsection in conjunction with increased terrestrial deposition.Hadrosaur remains suggest the previously unknown presence of kritosaurs and potentially a basal hadrosauroid, suggesting that the Foremost Formation dinosaur fauna was similarly diverse compared to faunas of well-characterized Campanian formations in North America.
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.
