A little shop/museum in Evanston doesn't seem like the place to find prehistoric treasures, but this unassuming building boasts some remarkable finds. There may not be any full-fledged dinos here, but there is a femur bone that once belonged to an Apatosaurus (aka Brontosaurus) and was put together, puzzle-style, out of 100 pieces discovered in Colorado. Plus, check out one of the world's largest fossilized carnivorous dinosaur eggs and the collection of fossils from every geological time period going back 3 billion years. The museum grew out of Dave and Sandy Douglass's personal collection of rocks and fossils, including some Dave found as a boy. So you might want to hand over a shovel when you get home and let your kids get to work. You never know what they'll come across!
