When a baby Tyrannosaurus rex sprinted onto Intrust Bank Arena's floor Monday, there was plenty of noise.
The 7-foot dinosaur roared, and 60 second-graders from Wichita Collegiate School roared right back with squeals of delight and fright.
The baby T. rex was brought to Wichita to highlight "Walking with Dinosaurs — The Arena Spectacular," which comes to the arena April 21-25.
"This is unlike anything we've ever had in Sedgwick County," said Sedgwick County Commissioner Tim Norton. "The creativity and imagination that goes with this show is the best.... It is an opportunity to see the history of the world played out in front of your eyes."
The $20 million show depicts the dinosaurs' evolution through the use of puppetry, electronics and robotics, said Chris Presson, the arena's general manager.
Some of the dinosaurs will weigh between 1 and 1.5 tons. The largest will be a brachiosaurus, 36 feet tall and 56 feet long.
The show was inspired by the award-winning BBC series of the same name. The traveling show was created for a stint in Sydney, Australia, in 2007 and has toured throughout the world since.
The show features 17 dinosaurs of 10 different species. Among them: a 10-foot-tall plant-eating plateosaurus; a 36-foot-long heavily armored stegosaurus with plates and spikes, and a ornithocheirus with a 38-foot wingspan.
To build each dinosaur, the show's creators used as much as 433 feet of hydraulic hose, 971 square feet of fabric, 53 gallons of paint and the power of 12 truck batteries.
It takes a team of three people — one driver and two puppeteers — to operate each large dinosaur.
Matthew Rimmer, spokesman for the Dinosaurs North American tour, said the show requires 25 semi trucks to haul the equipment.
"We will take up the entire arena floor with dinosaurs," Rimmer said. "We will have sets, over 300 moving lights and special effects. It is truly spectacular."
Mike Everhart, adjunct curator of paleontology at the Sternberg Museum of Natural History in Hays, attended the news conference and said he hoped the show would draw attention to Kansas' own rich heritage with dinosaurs.
"We do have our own dinosaur tracks from sandstone exposed near Lake Wilson," Everhart said. "When people come see 'Walking with Dinosaurs' they will see how dinosaurs lived, moved and behaved — and what they may have looked like."
