Unidentified "spike" - Tooth, Tusk, Rib Tip?

[sward]

I spent part of today on my normal hillside just exploring around. I was picking up the normal shark teeth, fish verts, crab claws, etc, when I came across this:

This find is much larger than the normal material I find on this hillside. It measures approximately 100mm long and approximately 20mm diameter on the large end. To me, it appears to possibly be some type of rib tip, as I see no signs of enamel. But if it's a rib tip, I'm having a hard time believing an animal this large when compared to the normal things I find.

Could it be something like a Protosphyraena rostrum?

I was thinking rostrum as well. Protosphyraena? Saurodon? Is Brent planting fossils for us already?!?!?!

I believe y'all are on the right track. Thanks!

By the way Dan, yes I believe Brent is already planting fossils for us. Right after I got started I came across a piece of crab claw. Who else could have done it?
