Something fishy about this one!

This is an image circulating around social media at the moment, purporting to show a " Professor Dimitrov" crouching in front of his discovery, a mermaid skeleton, made near Sozopol Beach, Bulgaria. 

You'll probably be unsurprised to learn that this is an example of clever photographic manipulation. The image, minus Professor Dimitrov, was entered into a Worth1000 photo effects competition, and placed 6th in Archaeological Anomalies 13. http://www.worth1000.com/entries/685114/mermaid-skeleton-found
It was entered by the user  "the1calledDANO", more of who's work can be found here: http://all.worth1000.com/artists/the1calledDANO

The original image the artist used is this one, which can be found here: http://wastedonarchaeology.wordpress.com/2011/10/21/a-few-thoughts-on-excavating-skeletons/

Professor Dimitrov was added later, presumably by the japester who first began circulating this as an actual discovery.
