Bibliographic record
Abstract
Saskomomys, new genus zoobank.org/ 3CD70AC7-2ECE-406B-BB8E-E480D644F963 Type species. Saskomomys lindsayorum, new species. Figure 10. Tables 2 and 3. Diagnosis. Differs from Omomys in being smaller in occlusal area of all compared teeth and in the following: p4 with indistinct metaconid, crest emitting from protoconid buccally oriented, linguallyseated paraconid, and short talonid that rises quite dorsally at its distal end; m1 and m2 narrower; m3 broader, with more rounded cusps, with paraconid located centrally; M1 less well-developed hypocone shelf; M2 more convex mesial margin and deeper notch at distal margin; M3 less triangular (i.e., more extensive hypocone shelf), relatively less extensive expansion of the base of the protocone lingually, lingual cingulum continuous or nearly so. Differs from Chumashius in having no distinct metaconid on p4, crest running from protoconid runs buccally rather than distobuccally, less lingually projecting paraconid; m1 and m2 narrower, less well-developed buccal cingulid; m3 hypoconulid lobe more isolated (i.e., constricted at its mesial end), trigonid longer at lingual side and more rounded mesially; M2 narrower (especially at protocone), greater extent of hypocone, more distinct conules, more distinct buccal cingulum. Differs from Dyseolemur in having less basal inflation and crenulation on the lower molars and in lacking a metastylid and the fovea separating the metastylid from the metaconid; m3 has more isolated hypoconulid lobe; M1 and M2 have smaller hypocone, conules, and buccal cingulum, with less-distinct crests emitting from the conules lingually; M3 has less-distinct buccal cingulum and is more triangular in outline (narrower at protocone than at buccal cusps). Differs from Ekwiiyemakius in having a shorter and broader p3 and m3; more constriction mesial to the hypoconulid lobe on m3; M1 buccal notch is more pronounced (deeper and narrower); M1 and M2 trigon basin and hypocone shelf are broader; M3 is longer (mesiodistal dimension). aSee also measurements in Storer 1984 and Storer 1990. Etymology. Prefix ‘ Sask– ’ in reference to the distribution of the taxon in the province of Saskatchewan. Suffix ‘– omomys ’ (Greek, “shoulder-mouse”) refers to omomyoid primates generally.
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.
