A DAWN convoy of giant dinosaurs has gatecrashed Chester Zoo.

The 13 American-made animatronic dinosaurs shuttled down the A41 on low loaders as part of a summer exhibition.

Featuring realistic movements and sounds, the dinosaurs include the giant apatosaurus, with its distinctive long neck and whip-like tail, the dilophosaurus, with its long, sharp claws, and the infamous tyrannosaurus rex.

The animated robots will be part of an outdoor trail.

Chester Zoo spokesman Will Conliffe said: “Each life-sized mechanical dino is one of 13 that will be on display in the new Dinosaurs at Large! exhibition at the zoo from July 1 to October 8.

“It’s the very first time these dinos have been in the UK and it is the biggest event/exhibition in the zoo’s 80-year history.

He added: “They’ve been brought over by Billings Productions Inc and they say it takes at least months to build a t-rex.

“The colour patterns are actually based on DNA research carried out on dinosaurs bone/fossils – meaning they’re as closely matched to the real things as they possibly can be.”
