Merrilee F. Guenther, Ph.D.

Associate Professor of Biology and Co-Director of the KEYSTONE Program
Department of Biology

Dr. Merrilee F. Guenther studies the paleobiology, biomechanics, growth and development of hadrosaurid dinosaurs and their relationships to modern birds and crocodylians. Her current research projects include:

  • The ontogeny and biomechanics of the postcranial skeleton of hadrosaur dinosaurs
  • The diversity of hadrosaur dinosaurs in the San Juan Basin, New Mexico
  • Ontogenetic changes (changes during the growth of the animal) in the biomechanics (structure and function) of hadrosaur jaws and determining how those changes differ across different species of hadrosaur dinosaur
  • The use of micropaleontology to reconstruct the ecology of western North Dakota during the Paleocene (55 to 60 million years ago) Epoc

Dr. Guenther earned a Ph.D. in Earth and Environmental Science at the University of Pennsylvania. Her doctoral dissertation focused on the “Morphology and Ontogeny of the Postcranial Skeleton of the Hadrosauridae.” She has also served as a visiting assistant professor of biology at Saint Joseph’s University in Philadelphia.
