Jonathan and Dr. Adam Hartstone-Rose feeding cubes of melon to a red ruffed lemur (Varecia rubra) to record bite size. This study was conducted at the Duke Lemur Center, Durham, North Carolina (taken in 2007 by David Haring).

  • Education:

  • Ph.D., Biological Anthropology and Anatomy, Duke University, 2008
    M.Sc., Systematics and Evolution, University of Alberta, 2001
    B.Sc., Paleontology, University of Alberta, 1998

  • Research Focuses:
  • Anatomy and biomechanics of the masticatory system
    Evolution of feeding adaptations in primates
    Material and structural properties of primate foods
    Craniomandibular morphology of Eocene primates
    Miocene platyrrhine dietary adaptatons

    I am interested in the link between skull form and diet. How do food properties influence skull morphology over evolutionary time and are there skull features we can use to reconstruct diet in extinct mammals. In particular, I am excited about the context for the evolution of primates and I am curious about whether changes in diet prompted changes to the skull that characterize the first primates. To address these interests, I have looked at links between the dimensions of the chewing muscles, bony skull features, and food properties in extant primates. I use these links to reconstruct aspects of feeding and diet in early primates (e.g., adapids). I am interested in applying these techniques more broadly and generating dietary hypotheses for other fossil groups (e.g., the archaic primates, plesiadapiforms). This has been the main focus of my research. In addition, I participate in several field projects to recover fossil mammals from localities across the world. I and my colleagues perform non-invasive, observational feeding experiments on captive primates to quantify feeding behavior. Finally, I collaborate on projects to quantify feeding energetics and to model tooth form in primates. All of this work is driven by a desire to understand the ways in which our earliest primate ancestors related to their environment.
