Fossilized Footprints Reveal Human Habitation of North America Thousands of Years Earlier than Previously Thought

ALAMOGORDO – New scientific research conducted at White Sands National Park in New Mexico has uncovered the oldest known human footprints in North America. The discovery reveals evidence of human occupation in the Tularosa Basin beginning at least 23,000 years ago, thousands of years earlier than previously thought.

Magmatism, migrating topography, and the transition from Sevier shortening to Basin and Range extension, western United States

The paleogeographic evolution of the western U.S. Great Basin from the Late Cretaceous to the Cenozoic is critical to understanding how the North American Cordillera at this latitude transitioned from Mesozoic shortening to Cenozoic extension. According to a widely applied model, Cenozoic extension was driven by collapse of elevated crust...
