Anatomy and Vertebrate Paleontology Faculty & Staff

If you have any questions about the Anatomy and Vertebrate Paleontology program at OSU Center for Health Sciences, please contact one of faculty members.

holly woodward ballardHolly Woodward Ballard, Ph.D., Professor of Anatomy
918-561-8263 |

Research Interests:

  • Intra-specific ontogenetic variation in growth of extinct tetrapods using large-sample paleohistology, with a focus on non-avian dinosaurs.
  • Integration of osteohistology with other techniques such as micro CT and stable isotopes to interpret the paleobiology and life history of extinct tetrapods.
  • Intra-skeletal histology throughout ontogeny in both extinct and extant tetrapods.
  • Increasing understanding of bone tissue microstructure in extant tetrapods for use as a foundation in paleohistological interpretations.
