Eight-year-old Jack Osbourne reaches out

Eight-year-old Jack Osbourne reaches out to touch the teeth of a moving life-size Tyrannosaurus Rex dinosaur during a press launch of "Walking with Dinosaurs" at the O2 Arena in London on March 18, 2009. The arena show, based on the award-winning BBC Television series, features 15 life-size dinosaurs. The dinosaurs come to life in a 96-minute show taking the audience through the evolution of the giant beasts from their first existence, over millions of years, through to their extinction.
