“Research projects by Stuart Birnbaum, University of Texas at San Antonio (UTSA) associate professor of geological sciences, and Daniel Lupton, a UTSA master’s student in geological sciences, reveal new information about Central Texas’ climate and water sources.
“Birnbaum’s team researched the ancient climate preserved in the chemical signature of samples from Kimble County, Texas, by taking rock samples from a 12-meter cliff exposure of the Hensel paleosol, an ancient soil estimated to be approximately 112 million years old.”
