Who- Rather What Are You!?

A young brunette stares in fear and awe, in front of her was a creature like no other. A creature many thought to have been extinct or rather never was real, a mythical creature that shouldn't have been in front of her was staring right at her. How in the world could no one have spotted it!? It was huge, she could imagine the creature reaching up to 24'7ft! And that was only laying down, the wingspan hit around 29ft, it's tail is like a whip. Long and thin, she froze when the beast started to rise from the ground. She was afraid to be eaten by it, what even was it exactly? Or rather, the second thought that crossed her mind, who was it? What was its name? Did it even have one?
