As low-latitude seaways closed, warm surface ocean currents were deflected into much higher latitudes (areas closer to the poles), and cool-water upwelling developed along the ... New Mexico was covered by the Permian Sea during the Paleozoic era , a vast, shallow body of water that created beds of limestone, sandstone, gypsum and shale.

The folds and thrusts were then eroded and carved by wind, streams and glaciers...The end-Permian mass extinction was the largest biodiversity crisis in the Phanerozoic. Based on characteristic negative ∆33S signals of sedimentary pyrite, previous multiple sulfur isotope studies suggested shoaling of anoxic/sulfidic deep-waters onto a shelf, leading to the shallow-marine extinction. However, the validity of this shoaling model has been controversial.
