Atlantis, looking as closely as one can at the "crock," what I see is a thick woven fabric in a brownish-gold color. Its actual shape is obliterated by both the black and the white damage, both of which conspire to give it the look of a crocodile. There appears to be a fold at the bottom of the "fabric", but that doesn't identify it. I would keep the fabric look and lose the black and the white damage, and then, as everyone else has suggested, fade it into the background.
This is one of those objects that will make you crazy trying to determine what it is when it's not that important to the photo. Cleaning it up and making it as unobtrusive as possible seems the most logical way to go.
