Ok, i know someone who would possibly squee at this.
Also my OCD on the subject is forcing me to point out that most, if not all of Skyrims dragons are actually wyverns.
Wikipeida on wyverns said:
Winged reptilian creature with a dragon's head, two legs (sometimes none), and a barbed tail.

And if youre going to try catch me out with that some of them stand on thier wings too, the Monster Hunter playerbase has already dubbed those pseudowyverns. Thats false-wyverns for those without a handy dictionary.
