The Maryland State Fairgrounds play host this weekend to Discover the Dinosaurs, a display of over forty animatronic dinosaurs from the Triassic, Jurassic, and Cretaceous periods, wagging their tales and snapping their jaws behind black insta-barriers like the kind that tell you where to stand in line at the movies. The exhibition bills itself as an educational experience, and technically it is that. Each dinosaur is accompanied by a sign sharing some facts about when it was discovered and by whom, what it ate, why its legs and arms are the size they are (those tiny T-Rex arms could lift 400 pounds each!), how big it was compared to today's standard-sized human, and more. There's a scavenger hunt that requires kids to at least read the names of dinosaurs to get the prize at the end. But the real selling point for the kiddos, if my visit was any indication, probably won't be the learning. Visitors enter the Cow Palace to get tickets and wristbands and then follow the roars past Walter, the animatronic paleontologist who welcomes visitors. Jake, my behind-the-scenes guide, emphasized how much kids can learn, but no, there isn't really a staff paleontologist, and no, they don't actually work with scientists or universities to put on the show. Then official photographers take your picture against a green screen that will turn into a scary dinoscene you can purchase later in the tour. The exhibit space is then divided by curtains that guide visitors past the various dinodisplays. Jake's favorite are the longneck dinosaurs, because they were the largest animal to ever walk the earth; their models aren't that big, though, because they have to get on a truck and go to Chicago next week. The figures are definitely cool, and the part where you can push buttons to make them move—I'll take it.
