Montana’s Two Medicine Dinosaur Center includes the world’s longest dinosaur – a skeletal model display of a Seismosaurus – according to the Guinness Book of World Records. Other displays include the first baby dinosaur remains found in North America, recently featured on CNN, and the actual remains of other new dinosaur species. Programs available through the Two Medicine Dinosaur Center of Montana are designed to allow participants to work beside actual research professionals and staff. Such interaction allows participants to learn current principles and techniques of fossil preservation, leading to better reporting and documentation of fossil discoveries.
