On any given day in Plymouth, there may be a pterodactyl hovering at the bus stop, a couple of T-rexes in the tinned goods aisle or a stegosaurus at the school gates. In most places, this would be enough to warrant a fair few double takes – but in the port city, it’s nothing out of the ordinary. Members of the Dinosaurs of Plymouth Facebook group, which has 5,600 fans, are locals – mainly parents – who bring joy to others by dressing up in inflatable dinosaur outfits. Many are women, and photos show them meeting up outside schools and nurseries, and pushing buggies, dressed in giant inflatable suits.
