whale bone ID?

[Rowboater]

Hoping someone knows what bone(s) this is (are).  I'm always amazed at what you people know!  The piece is about 5" long and heavy.  Looks to be two, maybe three pieces fused together, in a crude triangular shape (three faces). One face shows a length long line and from the end it is clear there are two separate pieces fused side by side. Another face is smooth with a shallow groove at the end (visible in the end picture). The last face shows fibrous bone turning into chipped cancellous bone on the end; the other piece or two appears to be cancellous bone.

What might be helpful in an ID would be a locality of where it was found

Unfortunately it was in a creek, not in a sedimentary layer.  Near the Rappahannock River in Virginia.

It looks a lot like part of a Whale skull, mybe from the side of the skull to me. George

Thanks for your help.  I guess it is a small fragment of fossilized bone that is difficult to ID from my photos.  I'll look up whale skulls on Google.
