Dr. Katy Smith studies tooth replacement rates among Sauropods
Sauropods replaced their teeth faster than any other type of dinosaur, which may have let them eat enough foliage to sustain their massive size. Dr. Katy Smith, Associate Professor of Geology and Curator of the Georgia Southern Museum, co-authored a paper in which the study also hypothesizes that differences in tooth replacement rates among the giant herbivores likely meant their diets varied, an important factor that allowed multiple species to share the same ecosystems for several million years.
