Since 2005, the Yale Peabody Museum’s Division of Vertebrate Paleontology has sent expeditions to North Dakota and Montana to prospect and collect fossils from the end of the “Age of Dinosaurs” and the beginning of the “Age of Mammals.” In this photo, from left, Lee Roach, Marilyn Fox, Kanvaly Bamba, Walter Joyce and Alison Logan gear up to spend the day hunting for fossils. |
