25 years of "B-rex": One Pretty Amazing Dinosaur In 2000, former Museum of the Rockies Chief Preparator Bob Harmon uncovered a remarkable T. rex fossil in Montana; later dubbed “B-Rex.” This specimen would spark one of the most groundbreaking discoveries in paleontology: evidence of soft tissue structures, including blood vessels and cells, preserved in 68-million-year-old bone. In this lecture, Dr. Mary Schweitzer recounts the scientific journey from initial skepticism to global impact, and how advanced technologies like molecular analysis and synchrotron imaging are helping unlock secrets once thought lost to time. Discover how B-Rex is redefining what we know about fossilization and dinosaur biology. What can fossils teach us about the world today? Discoveries made by paleontologists continue to shed new light on the deep past of the planet and the creatures that arose here. This speaker series explores recent paleontological findings and current hypotheses as conveyed by scientists who are actively exploring how life on Earth has changed. After the lecture, there will be a meet-and-greet with refreshments. Hager Auditorium Included with membership, $5/non-member Registration is required
