A new serial Cretaceous planktic foraminifer (Family Heterohelicidae Cushman, 1927) from the Upper Maastrichtian of the equatorial Central Pacific
Bibliographic record
Abstract
Abstract. A new serial planktic foraminifer, Lipsonia lipsonae nov. gen., nov. sp., is reported from the Upper Maastrichtian sediments of the equatorial Central Pacific (Shatsky Rise). It presents raised sutures throughout, ornamentation consisting of coarse irregular structures on the early part of the test and smooth test surface in the adult stage. The absence of costate ornamentation suggests that the new taxon origins should probably be found in the contemporaneous non-costate species of the Laeviheterohelix glabrans-L. dentata group. Lipsonia lipsonae presents morphological similarities with the Santonian genus Sigalia. The costate test surface and sutures of the latter indicates that it evolved from a costate species. Accordingly, Lipsonia and Sigalia are the results of iterative evolution from two different heterohelicid groups.

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.
