Dinosaur roars followed by laughs and screams echo from the St. Louis Zoo’s newest exhibit - The Emerson Dinoroarus. Zoo guests can watch the 16 types of life-like animatronic of dinosaurs move, spit water and even hatch from eggs as they walk through the exhibit, which opened to the public on April 17, 2021. The exhibit is free to zoo members with an overall reservation, and $5.95 per non-member guest ages 2 and up, with a reservation. Tickets are timed by entry, but once in, dinosaur explorers can stay as long as they like. Video by Sara Diggins, sdiggins@post-dispatch.com
