Scientists discover evolutionary link to modern-day sea echinoderms
Scientists at The Ohio State University have discovered a new species that lived more than 500 million years ago—a form of ancient echinoderm that was ancestral to modern-day groups such as sea cucumbers, sea urchins, sea stars, brittle stars and crinoids. The fossil shows a crucial evolutionary step by echinoderms that parallels the most important ecological change to have taken place in marine sediments.

Study on explosive volcanism during ice age provides lessons for today's rising CO2
A University of Oklahoma-led study recently found that explosive volcanic eruptions were at least 3-8 times more frequent during the peak of the Late Paleozoic Ice Age (~360 to 260 million years ago). Aerosols produced by explosive volcanism helped keep large ice sheets stable, even when CO2 levels increased, by blocking sunlight. But the volcanic emissions also may have started a cascade of effects on the climate system that resulted in additional CO2 removal from the atmosphere.
