From 121 collected samples, 31 that included a total of 126 taxa were applied to paleoenvironmental interpretations, and 20 well-preserved foraminiferal samples were analyzed with cluster analysis. In the Urumaco region, the upper middle to upper Miocene Urumaco Formation, which alternates among continental, marginal marine, and marine facies, was predominantly inner shelf, and the taxa and very low diversities suggest highly variable, low-salinity conditions. Foraminifera of the upper Miocene–middle Pliocene Chiguaje Member of the overlying Codore Formation indicate a deepening from inner to deeper-middle shelf. The middle to upper Pliocene San Gregorio Formation varies from estuarine in the lower Vergel Member to inner shelf in the overlying Cocuiza Member. In the Coro–La Vela region to the northeast, paleobathymetries are deeper, fluctuating from middle- to outer-neritic depths in the upper Miocene Taratara Member of the Caujarao Formation, and middle-neritic depths in the conformably overlying upper Miocene, basal part of the La Vela Formation. The relatively stable water depths of the Caujarao and lower La Vela formations support deposition on a stable marine platform. Overall, the shallower facies in the west and deeper facies in the east agree with the interpretation of an eastward progression of inversion of the Falcón basin from Miocene to Pliocene time. The middle Miocene–Pliocene shelf sequences of Falcón are compared to other formations of Venezuela and Colombia with similar paleoenvironments.

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.
