Life sized dinosaurs are coming to west London on Saturday (April 1) and the animatronic creatures went on a rampage through the capital before the opening.

Jurassic Kingdom, set to open in Hounslow, features more than 30 true-to-life dinosaur models but before they reached the borough, took a little city detour.

In a UK first, Osterley Park will transport visitors back to a time when dinosaurs ruled the Earth and Londoners got a sneak peek at the creatures before they get ready for visitors in the park.

Tourists, policemen and Londoners stopped to snap the beasts as they paced through the capital's busiest streets ahead of the opening.

A Tyrannosaurus Rex, standing 18 metres from head to tail, basked in the sunshine and startled passers by as scaly velociraptors growled at busking performers.

Those visiting Jurassic Kingdom can expect to see Diplodocus heads poke 16 metres above the ground amongst the tree canopy as Triceratops escort their young through the bushes beneath.

Meanwhile, ear-piercing screeches of the Pterosaurus will alert visitors to the danger in the skies above and guests must be wary of the spitting defence of the Pachycephalousaurus.

Younger visitors will be encouraged to pick up their brushes and become budding archaeologists in the Excavation Scene, where a T-Rex skeleton lurks just beneath the surface, waiting to be discovered.

Designed by Weli Creative - the team behind the Magical Lantern Festival - Jurassic Kingdom will kick off on April 1 until April 17.
