Brentford schoolchildren dressed as mini dinosaurs took part in a sponsored walk to raise funds for a class "pet".
Pupils from Year 2 at St Paul's CE Primary School in Brentford dressed up as their favourite prehistoric animal and walked 20 laps around St Paul's Recreation ground.
The 30 seven to eight-year-olds are aiming to raise £600 from their walk to buy a number of interactive PLEO dinosaurs.
"It was brilliant," said Alannah Chatir, administrator at the St Paul's Road school. "The dinosaur sleeps and moves just like a real pet, the children are going to vote for a suitable name."
The fundraising is part of the government programme Every Child Matters, which includes an "economical awareness" initiative, helping children to learn the value of money.
