Curriculum Vitae:

Daeschler CV

Research Interests:

  • Vertebrate paleontology, specifically vertebrate fauna of the Late Devonian Period 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, since 1999 on Ellesmere Island in the Canadian Arctic, and since 2016 in Southern Victoria Land, Antarctica.
  • 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.


Ted Daeschler has been at the Academy of Natural Sciences in Philadelphia since 1987. Ted studied geology at Franklin and Marshall College in Lancaster, Pennsylvania, and received a Masters in paleontology at the University of California at Berkeley in 1985. He was awarded his PhD at the University of Pennsylvania in 1998. Ted’s responsibilities at the Academy of Natural Sciences focus on research, collections building, and on public programs within the museum. He served as a scientific advisor for the renovation of the Academy’s Dinosaur Hall, and a variety of other paleontological exhibits. Ted’s work is a reflection of the rich history of vertebrate paleontology at the Academy of Natural Sciences, both in research and in public education.
