Dr. Stephanie Drumheller-Horton, Course Director (Biology)

Stephanie Drumheller-HortonMy research interests center on vertebrate taphonomy, ichnology, paleopathology, and paleoecology. In particular, I study bone surface modifications generated under modern and experimental conditions to better understand the processes which left similar traces on bone in the fossil record. My current research projects include:

  1. testing methods for applying these modern analogies in a deep time perspective
  2. interpreting trophic interactions, behavior, and diet from bite marks left by different archosaurian groups, especially members of Crocodyliformes
  3. identifying and differentiating historically understudied traces and pathologies, such as bite marks vs. shell disease and different types of plant mediated damage to bone.
