NASHVILLE (AP) — A dinosaur exhibit has been announced at the Nashville Zoo beginning next spring.

The DinoTrek display will show 16 prehistoric beasts living in a hidden forest. State-of-the-art electronics and air pistons will power their movements allowing them to hiss, move and roar. Each dinosaur will be built on a steel frame and covered with painted epoxy skin.

There will be a dinosaur sand pit where youngsters can dig for fossils. Special dinosaur education programs will be available.
