The English anatomist Richard Owen, a leading figure in Victorian science, coined the term 'Dinosauria' (from the Greek for 'terrible lizard') to describe a new suborder of fossil reptiles. He based this classification on the fragmentary remains of Megalosaurus, Iguanodon, and Hylaeosaurus, recognizing them as a distinct group of giant, extinct animals. Owen's term quickly entered the public vocabulary and became the enduring label for these ancient creatures, shaping popular and scientific imagination for generations.

Owen's naming of the 'Dinosaur' gave poets and writers a powerful, evocative label for prehistoric creatures, a term that became culturally potent in the late Victorian and Edwardian eras. The 'terrible lizard' provided a new lexicon for describing lost worlds and the sublime scale of deep time, which was quickly adopted by popular literature. This linguistic invention had a profound effect on how the prehistoric past was conceptualized and written about, and was central to the cultural ascendancy of the dinosaur in the transatlantic imagination.
