TEXAS —1 VERTEBRATE PALEONTOLOGY OF THE SOUTHERN HIGH PLAINS
Bibliographic record
Abstract
Texas Panhandle cover an area of approximately 50,000 square miles. That portion lying south of the Canadian River forms a broad plateau called the Staked Plains or Llano Estacado which is bordered on the north, east, and west by escarpments and which grades southward into the Edwards Plateau without any physiographic break. North of the Canadian River, the plains are continuous with the High Plains of western Oklahoma, Kansas, and Nebraska. The present High Plains surface has developed on a widespread sheet of Late Tertiary and Quaternary deposits laid down on a low-relief surface of Permian, Triassic, and Cretaceous sedimentary rocks. In the southern High Plains, this surface is underlain by the thick caliche caprock which occurs in the upper part of the geographically extensive Ogallala Formation. Locally, basins and valleys eroded in the Ogallala Formation have been filled with lacustrine and fluvial deposits of Pleistocene age. Erosion and deposition during Pleistocene and Recent time have modified the surface features on the plains and have also developed or modified the canyons and escarpments along the margins of the plains thus exposing some of the older geological formations. Today, strata of Permian, Triassic, Pliocene, and Pleistocene ages may be seen and studied along the "breaks " of the Canadian River and along the head ward tributaries of the Red and Brazos Rivers. With the exception of the Permian, these beds contain abundant vertebrate fossils and, as a result, the southern High Plains, especially the Panhandle regions of Texas and Oklahoma, have long been known to vertebrate paleontologists throughout the world. During the past 80 years many institutions have made extensive collections of Triassic and Cenozoic vertebrates. Among these are the American

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; both teacher heads agree on what is shown here.
