Molossid Bats from the Late Tertiary of Florida with a Review of the Tertiary Molossidae of North America
Bibliographic record
Abstract
(Uploaded by Plazi for the Bat Literature Project) The fossil history of molossids in the North American Tertiary is among the poorest for any family of bats. The oldest definite record is of Wallia scalopidens of middle Eocene (Uintan) age from Saskatchewan, Canada. One of the youngest records is of Eumops cf. E. perotis from the late Pliocene (late early Blancan) of Arizona, USA. New occurrences detailed herein from the middle and late Tertiary of Florida, USA, begin to fill in the 40million-year gap between the previous records. They are: (1) an abraded upper molar of an indeterminate genus from the Brooksville 2 locality, Hernando County, of late Oligocene (Arikareean) age; (2) a large and a small upper molar pertaining to two congeneric species similar to Tadarida and Mormopterus, from the Thomas Farm local fauna, Gilchrist County, of early Miocene (early Hemingfordian) age; and (3) a distal humerus from a Tadarida of an unknown species that is larger than extant Tadarida brasiliensis and similarly sized but differently proportioned than in the extinct Pleistocene species Tadarida constantinei. The last specimen is from the Macasphalt Shell Pit, Sarasota County, and is of late Pliocene (late Blancan) age.

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.
