An article in the January 2016 edition of EARTH: The Science Behind the Headlines summarizes research conducted in South Africa by Whipple-Coddington Professor of Geology Robert Gastaldo. Under the headline “Permian-Triassic extinctions timed differently on land and at sea,” the article explains how research by Gastaldo and colleagues, including dozens of Colby student researchers, has called into question the prevailing hypothesis that life forms on land and at sea were wiped out simultaneously in the Permian-Triassic mass extinction. The article links to Gastaldo’s article in GEOLOGY and to Gastaldo’s website, which includes information on his research.
