Extinct ice age giants in Bender's Cave challenge existing climate records for the Edwards Plateau

Phys · · 986 words · By Sandee Oster

Researchers from the University of Texas discovered Ice Age megafauna, including giant tortoises and pampatheres, in Bender's Cave on the Edwards Plateau. The findings suggest the region may have once had a warmer, wetter climate than previously recorded, potentially dating back to the last interglacial period.
