Ted Daeschler’s current research program in vertebrate paleontology focuses on the vertebrate fauna of the Late Devonian Period (385-363 million-years-ago) in eastern North America. The research involves active fossil collecting, systematic work focusing on freshwater vertebrates, and the nature of early non-marine ecosystems. Fieldwork is ongoing since 1993 in Pennsylvania and since 1999 on Ellesmere Island in the Canadian Arctic. Fossil discoveries from the incompletely-known Late Devonian interval help us to answer questions about the diversification of major groups of fishes, the origin of limbed vertebrates, and the invasion of land by plants and animals.

Other interests include the early history of vertebrate paleontology in North America. Links to web sites on this research: The Thomas Jefferson Fossil Collection and Joseph Leidy - Father of American Vertebrate Paleontology.
