Marsh Marigold Seed Pod

This I thought was a new flower I had not found before ..... something to add to my "life list". But, after about 2 hours of looking through one identification guide after another and about an hour or so on the Internet...... I found that this is not a flower at all..... it is the seed pod of the Marsh Marigold. This one is empty of seeds, which are usually very plentiful....  Isn't it beautiful?

Where I found it : in a swamp
