The Louisville Zoo unpacked 16 robotic dinosaurs Wednesday for an exhibit that will open to the public March 22.
The Dinosaurs Alive exhibit will feature brachiosaurus, tyrannosaurus rex, the deinonychus (whose name means the "terrible claw") and the cryolophosaurus, nicknamed the "Elvisaurus" because the shape of its skull resembles Elvis Presley's hair.
A sound system allows the dinosaurs to roar, and they can move, thanks to electronics and air pistons that power claws and teeth. The dinosaurs were built on steel frames by Billings Productions of McKinney, Texas.
Visitors will be able to operate one of the creatures using a remote control box.
The exhibit will be open March 22 through Sept. 30. A special attraction fee will be charged — $4 for zoo members and $5 for non-members — in addition to regular zoo admission. Children 2 years old and under are free. On the zoo's Web site, regular admission is $11.95 for adults and $8.95 for children ages 3-11 and seniors age 60 and older.
