In this revelatory series Professor Richard Fortey, Britain’s foremost chronicler of ancient worlds, tells the extraordinary history of paleontology through three of the world’s greatest fossil sites. These fossil ‘time capsules’ contain entire eco-systems of now-vanished worlds. Only a handful of them exist in the world, but each one of them has overturned generations of paleontological thinking and reconfigured our understanding of the past. These ‘super-sites’ are uniquely special not just because of the scale of the life preserved but because each location reveals a history of evolution of one type of creature and highlights three key evolutionary moments: early life in the seas, feathered dinosaurs and the rise of birds and the birth of mammals. Together they tell a story not just of the ancient past, but how that past was discovered. A BBC Production.
