Long time ago, before your time, the time which will be called Triassic later, we lived with our friends in a land called Earth's Middle Ages.
You will only know about us from the history books, and you will come up with various theories why we became extinct.
But I'll tell you how it was then and how we lived.
Are you sure we don't exist anymore?
Are you always remains the same?
Now I want to start with my story.
