snaggle Posted October 6, 2009 Share Posted October 6, 2009 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. Anne Link to comment Share on other sites More sharing options...

Boesse Posted October 7, 2009 Share Posted October 7, 2009 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). Bobby Link to comment Share on other sites More sharing options...
