Owen coins Dinosauria in 1842 from the fragmentary remains of Megalosaurus, Iguanodon and Hylaeosaurus. Life-size concrete models are unveiled at the Crystal Palace in 1854 — wrong in almost every detail, and still standing. Public fascination with dinosaurs does more than any argument to make the idea of a vanished deep past concrete, and the American bone rush of the 1870s turns palaeontology into a competitive spectacle.
