Dinosaur

A dinosaur was any of a wide number of reptile species belonging to the clade Dinosauria that lived from 237 million years ago to the time of Harry Potter.

After hearing Madame Olympe Maxime claim that she had "big bones" rather than admit to being half-giant, Harry Potter remarked that the only thing that had bigger bones would be a dinosaur.
