SMU Earth Sciences, Antarctica

Earth Sciences master’s student Chris Strganac, doctoral student Yosuke Nishida and Professor Louis Jacobs are part of a team traveling to Antarctica to discover 120 million-year-old mammal fossils from Livingston Island and other places around the Antarctic Peninsula.
They hope to link the evolutionary history of mammals across South America to Africa and Australia through ancient Antarctica when climates were warmer. So far in their journey, as chronicled by Chris, they have found ancient plants, but mammal remains have been elusive. They are still looking…
