Some new acritarch species from the lower and middle Miocene of the Porcupine Basin, North Atlantic Ocean: biostratigraphy and palaeoecology
Bibliographic record
Abstract
Six new acritarch species were observed during a high-resolution study on the upper Burdigalian to Serravallian (lower and middle Miocene) of the Porcupine Basin (Integrated Ocean Drilling Program Leg 307, off southwestern Ireland). The stratigraphical ranges and palaeoenvironmental preferences of the six new species were assessed. Cometesphaera bullatio gen. et sp. nov. is recorded from the upper Burdigalian to the lower Serravallian, while the range of Cymatiosphaera? deverteuilii sp. nov. is restricted to the upper Serravallian. Platycystidia manumii sp. nov. is recorded from the upper Burdigalian to the upper Langhian. Porcupinea collaris gen. et sp. nov. and Porcupinea indentata gen. et sp. nov. range from the upper Langhian to the lower Serravallian, and from the uppermost Burdigalian to the upper Serravallian, respectively. Pusillisphaera solaris gen. et sp. nov. is recorded from the from the upper Burdigalian to the upper Serravallian.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
