Objectif(s): To study the extinction and rapid evolutionary changeovers of graptolites during the late-middle Silurian era; to collect rocks containing specimens of these fossils from two localities on northern Cornwallis Island as well as from several localities in central Ellesmere Island. This research is part of a long-term study of graptolites in the high arctic.
Description du projet: As part of a long-term study, the researcher will continue to collect fossil specimens of graptolites in rocks collected from northern Cornwallis Island and central Ellesmere Island. The researcher is investigating why some species became extinct over 415 million years ago while other species went through rapid changes.
