Make use of it. Dragon Corpse of Holding.

If only he would be that dependable...lol! It makes me laugh, can you see the Dovakin appearing in town, a big dragon corpse dropping from the sky and the Dovakin says, "Yeah that's my pet Dead Dragon knapsack."

I had this issue on one character. I fixed it by not fast traveling from his dropped location, and walking the width of Skyrim. The next time I fast travelled, no dragon. Maybe it will work for you, I think it hit it's clean up time in the location I left.

bug in the dragon clean up script I guess. I get it sometimes too.

Yeah, I could, but it isn't that big a deal. Besides, he looks kinda cool, draqed over my roof at the Lake House. (LOL)

I've been having this issue for a while too. Play on console, only started about a month ago and in the last week have been discovering dead dragons all over the place.

Walked out of Dragonsreach and there was a wing poking through the bridge, he was spasming in the water... guess he drowned waiting to pounce on me...

Or a stalker maybe the Dragon wants to get freaky with the dragonborn

Clearing the cache should clear the dragon as well, if you are on the Xbox 360 just clear the system cache to get rid of it. Not sure how you would do it on the PC/PS3.
