Our May general meeting will feature John A Moretti, from Jackson School of Geosciences, University of Texas at Austin. He will describe the famous Inner Space Caverns, how its Ice Age fossils inform our understanding of the ancient history of the Texas Hill Country, and how changes in the past led to the biodiversity of today.

Program Topic
Since its discovery in 1963, Inner Space Caverns (https://innerspacecavern.com), located in Georgetown, north of Austin, has been famous for its rich abundance of Ice Age fossils, representing mammoths, extinct horses, saber-tooth cats, and other animals that went extinct over 11,000 years ago. Recently, new fossils have been recovered of bats, jaguars, and tiny antelope-like pronghorn. Research and analyses of those fossils are providing new insights about the origins of the native fauna of Texas. Inner Space Caverns contains one of the oldest, longest, and most important troves of Ice Age fossils anywhere in Texas. Come learn more about this famous cave and the ancient history of the Texas Hill Country!

About our Presenter
John Moretti is a doctoral candidate studying vertebrate paleontology in the Jackson School of Geosciences at The University of Texas at Austin, and ardent caver. His research seeks to document natural history and investigate patterns of change in the animal community of North America over the past 3 million years. He explores caves across the Edwards Plateau of Texas, obtaining new evidence of how animal communities change over time, and how such changes have led to the biodiversity of today.
