Story book? Something man made up?
Like Darwin's book, "On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life"?
Never not once in the history of books has there ever been embellishment of any kind on any page.....ever.
I notice the book also mentions dragons multiple times. That does not mean that dragons ever actually existed.
Changing the subject to something else does not make a large vegetarian big-tailed animal a dinosaur.
