Dr. Mary Schweitzer studies dinosaur bones, as many paleontologists do. But recently she has been rewriting the rules of fossilization with her research at the microscopic and molecular levels. Her most fascinating finds have included preserved soft tissues, such as collagen and what appear to be ancient blood vessels, inside a 68-million-year-old T. rex. Come discover how her research has confirmed many connections between dinosaurs and birds and astonished scientists who have long believed that soft tissues would never be found inside fossilized bone.
About our speaker
Mary Schweitzer is an associate curator of paleontology at the NC Museum of Natural Sciences and a Professor in the Department of Biological Sciences at NC State University. Her discovery of still-soft tissues inside the bones of Tyrannosaurus rex and other dinosaurs called into question our understanding of how fossils form, and how tissues degrade (or preserve). She received a PhD in Biology and a Secondary Education Teaching Certificate from Montana State University, and a Bachelor’s degree in Communicative Disorders from Utah State University. She has been at NC State and the Museum of Natural Sciences since 2003.
