This episode of "Dissecting with Emily" continues our series of episodes on the holotype (name-bearing) specimen of Tyrannosaurus rex (CM 9380). In this episode, Ohio University Honors Tutorial College sophomore Emily Caggiano focuses on some mysterious features on the surface of the maxillary bone (the main upper jaw bone). We thought some of these features might be due to injury and pathology (like we saw more clearly on the dentary bones: bit.ly/2k85PdK), but now we wonder if they might have to do with specializations of the skin, perhaps related to behavioral display.
