Crowds get close to one of the dinosaurs at the event in Worksop town centre.
Throughout the day there were live dinosaur shows which attracted scores of people to watch in the Old Market Square.
The event had been organised by North Notts BID to attract more visitors into the town centre.
The packed programme of dinosaur-related activities featured opportunities to meet and learn about the historic creatures, including a fossil dig - which was organised in partnership with Odin events.
Worksop mayor, councillor Tony Eaton, joins in with one of the dinosaur shows by being on poo duty.
Chief executive at North Notts BID, Sally Gillborn, said: “We were delighted to put on this free dinosaur themed event for families in North Notts.
"The turnout was fantastic, and it was great to see everyone show their love for dinosaurs and the enjoyment that the activities put on everyone’s faces.”
Stalls and visitor attractions on the day included Worksop Town FC and Harworth play centre Kidz Hub who brought along their electric go karts.
Sally added: “Thank you to all the people who were involved in the organisation of the dinosaur discovery day and those who turned out on the day to help make it a roaring success.
