OK, so this is a tough one.  I can say that it’s not a sea urchin spine, nor damsel fly, nor stick, but what is it?  The picture is not detailed enough in resolution to give you a definitive answer, but I have an idea.  Does it have horizontal lines (relative to the long axis) on one side and smooth on the other.  If the answer is yes, I would say it is a single section of a stingray mouthplate assembly.  Otherwise, I would have to see a better quality picture, and I would still probably not be able to help you.
