October 4, 1915. President Woodrow Wilson designates Dinosaur National Monument as a national historic site. That’s a big deal, right? There must’ve been a grand ribbon-cutting ceremony, maybe even a parade. But no. In 1915, nobody really cares about dinosaurs. But that is all about to change. And when it does, it is largely because of two paleontologists. Two guys who started off as best friends … until their growing obsession with unearthing and cataloging dinosaur bones would turn them into rivals. Then enemies. How did the competition between a pair of paleontologists lead to unprecedented dinosaur discoveries? And how did their rivalry unhinge them both?

Special thanks to guest Dr. Hans Sues, curator of vertebrate paleontology at the Smithsonian’s National Museum of Natural History.
