This paper is a product of our collaborations with Dr. Russell Reid MD, PhD at University of Chicago, Olga Pangiotopoulou, PhD at Monash. Two Pritzker School of Medical Medicine students worked on this paper, with Pranav Haravu leading the charge. Thanks to all involved.
Thanks to Craig Byron for leading the charge on this great paper reporting in vivo bone strain from multiple sites across the sagittal suture in capuchins. These are important data on the variation in strain along the suture and across different behaviors.

The Ross Lab has a long-standing interest in the evolutionary biomechanics of non-mammalian vertebrates, especially crocodylians and lepidosaurs.
The Ross Lab is working closely with the Luo Lab to better understand the evolution of the mammalian mandible. We are using the opossum feeding system as a tool for understanding how best to model transformations of mandible form in early mammals. Kelsey Stilson is studying the role of periodontal afferents in control of 3d jaw movements during chewing in opossums. Alec Wilken is studying loading and strain regimes in the mandibles of opossums and early mammals.
We are working with Olga Panagiotopoulou at Monash University on finite element modeling of the mandible of Macaca during feeding and with Felippe Prado’s team at UNICAMP in Brazil of FEM of the mandible of Sapajus.
The Ross Lab has a long standing interest in craniofacial function during feeding in primates. Experimental studies are informing studies of muscle architecture dynamics and sagittal suture function in capuchins.
Field studies of wild capuchins in Brazil and Suriname (with Barth Wright, Kristin Wright and David Strait) have yielded important data on relationships between feeding behavior, food mechanical properties, and feeding posture. This important work continues with ontogenetic studies of capuchin feeding behavior under Myra Laird, Claire Terhune, Janine Chalk-Wilayto, and Megan Holmes.
