A recent study reveals that the plants—which were first unearthed by U.S. Army scientists in the 1960s and only recently re-observed—may indicate that the planet has previously undergone periods of warming climates. Published on Science Direct, the study describes how University of Vermont scientist, Andrew Christ, was shocked to see plants and sediment in the frozen dirt that the U.S. Army scientists had sampled.
