Bivalves: An Eon of Evolution. Paleobiological Studies Honoring Norman D. Newell
Bibliographic record
Abstract
Since their origin in the Early Cambrian, the bivalve molluscs have evolved a remarkable variety of forms that reflect their diverse habits through the Phanerozoic Eon. The thirty papers in this volume represent the proceedings of an international symposium on the paleobiology and evolution of the bivalves held at the Royal Tyrrell Museum of Paleontology in Drumheller, Canada, from September 29 through October 2, 1995. An international group of authors, representing a dozen countries, draw on diverse aspects of both fossil and living bivalves, including their forms, functional morphology, morphogenesis, taphonomy, shell microstructure, cladistic relationships, biostratigraphic distributions, and molecular sequences. The result is an authoritative and comprehensive collection of studies dedicated to Dr. Norman D. Newell, an eminent paleontologist whose ongoing contributions to the study of bivalve evolution spans six decades. With more than 200 illustrations and a foreword by renowned paleobiologist and author Stephen Jay Gould, Bivalves: An Eon of Evolution presents a broad spectrum of current research on fossil and living bivalves.

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.
