This looks like a fish or stingray spine, to me. 

Wait for some other opinions, though.

+1 for stingray spine. Interestingly, it has a mild pathology. In the top photo you can see that there are two overlapping rows of spines on the upper surface, whereas there should only be one row. This is not terribly uncommon, as abnormalities are fairly common on stingray spines. They seem prone to abnormal development. However, they are always interesting to find. I believe one of the researchers at the Calvert Marine Museum was putting together a paper on these abnormalities, but I never heard if the study was finished or not.

BTW, just for clarification, when you say "stingray spine" you are talking about the caudal spine a.k.a. stingray "barb", correct?

Barbs are the small protrusions on the edges of the spine that make removal difficult once the spine has penetrated flesh. The barbs are part of the spine. The terms are not interchangeable. They have the same function as the barb on a fish hook. Google an image of stingray spine.

Mark.

 

Fossil hunting is easy -- they don't run away when you shoot at them!
