Your nephew is 7 years old. You ask your sister what he wants for birthday.

"Anything to do with dinosaurs," she says.

In most cases, that would mean a trip to the nearest toy or hobby shop for a plastic model, battery-operated toy or even a T-shirt.

This year, there is another alternative.

Wednesday afternoon, officials at the Bradley Center unveiled plans for "Walking With Dinosaurs -- The Live Experience," a $20 million production created by the producers of the BBC series "Walking With Dinosaurs."

The show features 15 life-sized dinosaurs, which took a year to build and weigh more than a ton.

"They're as close as you can come to meeting something from when dinosaurs roamed the earth," said Bradley Center President Steve Costello, who announced the Dinosaur show along with several other events that will lead up to the building's 20th anniversary in 2008.

"Our 20th seasonwill unquestionably be our most significant year yet for special event programming," Costello said.

Tickets for "Walking With Dinosaurs" cost $35 and $69.50 and will go on sale at 10 a.m. Sept. 21 at the Bradley Center box office and Ticketmaster outlets.

In addition to games featuring regular tenants like the Bucks, Admirals and Marquette, the Bradley Center unveiled other upcoming shows for the venue. Here is a list:
