Fossil plants' ties to ancient carbon redefined

...115 million years ago from clathrates, deposits of methane on the bottom of the oceans. "That's a large reservoir of carbon that we haven't seen change dramatically in human times, but through these means we can identify it as a major player in the carbon cycle through geologic time," she notes. "It's a more...
