Marine Bone Id?

Care to take a stab at it? Marine environment. It is broken at the small neck, suggesting a small diameter extension to something else. The grid is in 1 inch squares.

This is the posterior process of a petrosal (inner ear bone) of a baleen whale. This projects laterally toward the side of the skull, and is wedged between the squamosal and exoccipital bones. This is probably from a balaenopterid (although I confess I don't remember what balaenid petrosals look like).
