University of Texas at Austin geologist Peter Flaig of the Jackson School of Geosciences went to Antarctica in search of fossils. Surrounded by snow and ice, he and his colleagues discovered the footprints of horseshoe crabs, burrows of small mammal-like reptiles and the remains of forests, all signs of a much warmer time millions of years ago.
