PALMETTO, Fla. — The live-events company Feld Entertainment is best known for the Ringling Brothers and Barnum & Bailey Circus, which closed in May 2017 as slumping ticket sales and rising concerns about animal mistreatment ended a cotton-candy-filled era in arena entertainment.

But the shutdown of the circus was not the end for Feld. It had been years since “The Greatest Show on Earth” was the core of the company’s business, which has long hinged on shows like Disney on Ice and Sesame Street Live.

Now, in the latest addition to that portfolio, Feld is replacing the lions and tigers that once strode across its stages with an even more formidable creature: Tyrannosaurus rex.

With rippling muscles made from Styrofoam beans and pebbled skin modeled on the dinosaurs in the Jurassic Park movies, the 17-foot-tall animatronic T. rex is the main attraction in the Jurassic World Live Tour, a new arena show that Feld opened on Thursday in Columbus, Ohio.
