However, in both HBO adaptations, the dragons on the Targaryen sigils are depicted with four legs.

Martin explains that this change, seemingly minor, is significant within the context of his detailed world.

Ergo, in my books, the Targaryen sigil has two legs, as it should.

Someone got sloppy, I guess.

Or someone opened a book on heraldry, and read just enough of it to muck it all up.

The shift from two to four-legged dragons in the shows remains somewhat of a mystery.
