 One dinosaur appeared in literature even earlier, as Charles Dickens placed a "Megalosaurus" in the first chapter of his novel "Bleak House" in 1852.The dinosaurs featured in books, films, television programs, artwork, and other media have been used for both education and entertainment.The depictions range from the realistic, as in the television documentaries of the 1990s and first decade of the 21st century, or the fantastic, as in the monster movies of the 1950s and 1960s.
