@golguin: I know of the difference physically, but the souls says it is of a dragon. Which makes it all the more interesting.
It's a matter of knowing who wrote the description from a lore perspective. We know that certain items are straight up wrong because we know the lore from the first game. Havel's equipment and Elizabeth's Mushroom are two big ones.
The descriptions are written as if some historian is trying to piece together the information that's currently available.
