The summer fun dino event, Roar & Seek, is at Queensgate until the end of the month and is free for all visitors to enjoy.
As well as the caged beasts, 15 augmented reality dinosaurs are 'roaming' the shopping centre and can be spotted via a free app for smartphones.
Take a raptor selfie and upload it to social media with the #RoarAndSeek hashtag - everyone who does will be automatically entered into a prize draw to win a family ticket to Gulliver’s Dinosaur Park and Farm in Milton Keynes.
In addition, everyone who completes the trail has the chance to be entered into a prize draw to win a weekly prize which could see winners take home a £50 gift card for use at Queensgate.
And all little explorers who complete the trail will be invited to collect a dinosaur colouring book and sticker sheet as a reward for their hard work from the customer information desk outside the O2 shop.
Find out more about the event and for links to download the app on the Queensgate website.
