CLEVELAND -- A popular attraction of prehistoric proportions is roaring back to life at the Cleveland Metroparks Zoo this summer.

Guests will be taken back in time as the shores of the zoo's Waterfowl Lake rumble withsounds echoing from "Dinosaurs!" -- the special exhibit, which runs daily from May 9 through Sept. 15.

"'Dinosaurs!' is one of the most popular seasonal exhibits we've ever brought to the Zoo," Executive Director Dr. Chris Kuhar says. "We haven't had them here for a couple of summers and we received a lot of requests from guests to bring them back."

"Dinosaurs!" features 21 dino displays with 15 different species, six of which are making their Cleveland Zoo debut --including Quetzalcoatlus, one of the largest winged creatures that ever lived, and Troodon, one of the first fossilized dinosaurs found in North America. They will be appearing alongside returning favorites like the mighty Tyrannosaurus Rex and the towering Brachiosaurus.

The robotic dinosaurs use air pistons and state-of-the art electronics under steel frames covered with detailed foam rubber skin to simulate their lifelike appearance.

Admission to this special exhibit is $3.50 per person, or $2 each for zoo members. Children younger than 2 are free.

In 2012, Cedar Point unveiled its own animatronic exhibit --"Dinosaurs Alive!" -- showcasing dozens of dinos near the Millennium Force roller coaster.
