When the Stegosaurus family, Mr and Mrs Stigson and their son Darwin, throw a party for Uncle Loop's 150th birthday, it is gate crashed by Clint Beastwood, the gangster like T-Rex and his thuggish side kick Mr Cretaceous (a terrifying Dinosuchus) and Terry O'Dactyl (a psychotic Pteranodon). War seems to be on the horizon for the carnivores and the herbivores as kidnaps and thefts follow. Boris, the Mayor, (a Triceratops) proposes Olympic Games to bring peace and stop the fighting. But can the dinosaurs settle their differences through sport or will it only make things worse? Jeanne Willis's madcap characters and story with Arthur Robins' inspired illustrations are certain to delight everyone's funny bone!
