Research Description: The Holliday Lab focuses on the structure, function and evolution of the vertebrate head with particular emphasis on reptiles (lizards, crocodilians, dinosaurs, and birds). Using a variety of classical anatomical techniques (dissection, histology) and imaging (CT, MRI), the lab investigates the relationship between diet, environmental factors, and age on the adaptive plasticity of the connective tissues (e.g., cartilage, bone, ligament, and muscle) of the heads of lizards and alligators. These data are then used to not only investigate the intimate relationship between cranial form and function in living animals, but also to infer the feeding behavior, cranial function, and phylogenetic relationships of fossil taxa, particularly crocodyliforms and non-avian dinosaurs.
