The Hangay Mountains of central Mongolia today serve as a large topographic barrier blocking moisture from reaching the Gobi Desert and interior Asia. Stanford doctoral candidate Jeremy Kesner Caves examined the uplift of the Hangay in the early Neogene,...
Fossilized leaves hold evidence of a sharp increase in carbon dioxide levels as the Antarctic ice sheet began to shrink 23 million years ago, a new study finds. This magnified image of a fossilized Litsea calicarioides leaf clearly shows...
