PALYNOLOGY OF THE EOCENE-OLIGOCENE DABAA FORMATION, QATTARA DEPRESSION, NORTH WESTERN DESERT, EGYPT
Bibliographic record
Abstract
The palynological investigations of 30 surface samples collected from a series of stratigraphic sections have been constructed for a number of sites in the Qattara Depression, north Western Desert, Egypt. Only 6 samples have yielded a very well preserved and diverse assemblage of palynomorphs including pollen and spores, dinoflagellate cysts, acritarchs and other miscellaneous palynomorphs including fungal palynomorphs and colonial algae . The productive samples are not dated before, but our palynological investigations revealed Late Eocene- Late Oligocene age (Chattian), for the Dabaa Formation. This allows for the first time a major revision and new interpretation of the lithostratigraphy of this area. Our biostratigraphic conclusions are based on the local, regional and global correlations of our recorded assemblages with other published dinocyst and spore-pollen distribution patterns from different Eocene/Oligocene stratigraphic sites all over the world.

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.
