Move over, Sue, there's another T. rex in town! Sure, Jane technically lives in Rockford and is about half the size of her more famous cousin, but that 21-foot-long skeleton still is pretty impressive. The "Jane: Diary of a Dinosaur" exhibit explores what happened during the 66 million years she was stuck underground and simulates the Montana dig site where her bones were first discovered. Plus, kids can check out the lab to see the skull of Homer, a "kid" just like them. The juvenile triceratops was only discovered in 2005, so if you're lucky, you can spy staff members working on his bones for a new exhibit opening in 2013. Then see if your kids can figure out what zoo animal the horned fellow resembles most.
