Late Pleistocene and Early Holocene Vertebrates and Paleoenvironments on the Southern High Plains, U.S.A.
Bibliographic record
Abstract
Only a few vertebrate faunas are known for the Southern High Plains from the late Pleistocene and early Holocene. This review focuses on vertebrate local faunas from two major localities on opposite sides of the region but in the same drainage system that provide proxy data for paleoenvironmental reconstructions from ca. 11,600 to 8600 yr BP. Both localities are archaeological sites within deeply stratified, radiocarbon-dated deposits. Four distinct, successive vertebrate local faunas are known for Lubbock Lake covering the period 11,100 to 8600 yr BP. Two distinct, successive vertebrate local faunas come from Blackwater Draw Locality # 1 for the period 11,600 to 10,500 yr BP. All of the local faunas are disharmonious but the extent of disharmony and diversity varies. Faunal elements from the Northern Plains and Southeast are the most notable. The late Pleistocene local faunas indicate mild winters which did not maintain freezing conditions and cool summers with a more effective moisture regime, reduced annual temperature fluctuation, and less seasonality. The beginnings of a warming trend, greater seasonality, and increased annual temperature fluctuation denote the early Holocene. The latest local fauna marks the last of the pluvial-related ones and heralds the end of pluvial conditions beginning around 8500 yr BP. The successive local faunas illustrate the complexity of disharmony occurring in unglaciated regimes during déglaciation of North America.

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.
