FLORAS TROPICALES CRETÁCICAS DEL NORTE DE MÉXICO Y SU RELACIÓN CON FLORAS DEL CENTRO-SUR DE AMÉRICA DEL NORTE
Bibliographic record
Abstract
Previous studies suggest that tropical and paratropical forests dominated by angiosperms had an important distribution throughout North America during the Early Cenozoic (Paleocene-Eocene). Recent research indicates that warm and wet forests were present in northern Mexico and south-central of U.S. during the Late Cretaceous (ca. 73 Ma). In Coahuila, the floras from the Cerro del Pueblo and Olmos formations represent vegetation types with tropical and paratropical affinities. In this paper we briefly review of the floristic composition and physiognomy of leaf and wood, and paleoecological interpretation of the floras from the Western interior of North America and northern Mexico. In addition, we analyzed floristic similarity patterns based on wood morphogenera. We show that floristic similarity patterns among paleofloras observe some geographic structure. There are, however, some morphogenera widely distributed across the region and other endemic to particular floras, which might suggest some degree of floristic differentiation. The validity of the patterns presented here is however preliminary and contingent to further identification of the fossil from these formations.

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.
