Palaeontologist Dr Tori Herridge explores exciting subjects from Britain's history. The Jurassic Coast of Devon and Dorset is one of Britain's great natural treasures and a World Heritage Site, but how did it come to be? Tori walks from the 150-million-year-old cliffs of Kimmeridge at its eastern end, back through time to the even older red cliffs of Budleigh Salterton, to reveal why the Jurassic Coast is stuffed to the gills with world-class fossils. Along the way she encounters the biggest sea predator ever to have lived and a global disaster that nearly destroyed life on our planet.
