No bones about it - learning about dinosaurs is fun! Join us as we visit three different sites and find out about animals that lived in the USA millions of years before man appeared here. At Mammoth Site in Hot Springs, South Dakota, we discover that wooly mammoths and other animals became entrapped and died in a pond 26,000 years ago in the Pleistocene Era. They lay buried until 1974 when earth-moving equipment exposed the fossils. Today this research center and active dig attracts visitors daily and has the largest mammoth exhibit in the world. Next we move to Nebraska to visit the Agate Fossil Beds National Monument. Originally a working cattle ranch until fossils were found there in the early 20th century, it was authorized as a national monument in 1965 but didn't become a part of the National Park Service until 1997. This site is in a grassy valley of the Niobrara River, and the fossils date from 20 million years ago in the Miocene Era. Visitors can hike the trail that winds along the University Hill and Carnegie Hill where the fossils were found and are now on display. Our search along the Dinosaur Trail ends at the Wyoming Dinosaur Center where there are skeletons of more than 20 dinosaurs on display. We witness a dig with a staff paleontologist and learn the process of preparing a fossil for display. We even get to see a skeleton of T Rex, the king of the dinosaurs!
