Bakersfield bone and teeth ID part 2

[Biconoid22]

Here are some bones and teeth from Ernst Quarry in Bakersfield that I can't figure out what they are. They are unusual and stand out from everything else I have collected there. The longer bone I suspect is fish or bird. The one on matrix with a fish and sea mammal vert I thought was a whale ear bone at first but I am not sure because of the weird shape. It almost seems like some sort of tooth. There is another included that is very similar it but not on matrix.

Can't figure out what this is either. Almost looks like part of a skull.

The last bone is an axis vertebra . . . the toothlike process, or "dens," is the telltale.

The top photo is the rear end of a fish jaw I have several more complete specimens like it.
