Iguanodon
c. 126-122 million years ago · Event
The dinosaur that started dinosaur science: teeth found in Sussex around 1822 led Gideon Mantell to describe a giant extinct reptile — only the second dinosaur ever named, before the word 'dinosaur' existed. Victorian reconstructions put its thumb spike on its nose; the plant-eater itself, thumb-daggers correctly in place, roamed Europe in herds a hundred million years before its discoverers.
