Flotsam of the Day

While running on the beach early this morning I was surprised to find a large, C-shaped bone in the sand, measuring about 8″ x 4″. My first thought was that it resembled part of a skate, a familiar inhabitant of the surf off Doran Beach. I don’t know much about bones, but its symmetrical shape suggests either part of a jaw or pelvis, and the tapered ends imply connection to some flexible part or hinge. I’d love to hear if anyone knows what it is.

Doran Beach is often loaded with colorful sand dollars at low tide this time of year
