I have found this thing in a campanian marine phosphate deposit. It came along with fish and shark teeth. It looks like some kind of tooth, but I have no idea. The brown area is translucent and looks like enamel. Although the grey is thicker and sharp.  Any experts on cretaceous fish would be welcome :)

 

Ps. This is definately not just a rock, I am fairly familiar with this deposit and can judge a rock from a fossil.

Could anybody I'd this please?

It is a Hadrodus bony fish pharyngeal tooth, here is an image of one from Menuha formation (Israel, taken from Wikipedia)

Not sure what the object on the left is though, could be a piece of another Hadrodus too

At 4 cm (1.575 inches) that would be an extremely large pharyngeal tooth.

I think it is a piece of something.

It reminds me of a gill raker. But that would be a huge one.

Well, you live and learn. I would never had expected a pharyngeal tooth to be this large.

I was thinking Hadrodus/Stephanodus like Eric.  However, I've never seen a Hadrodus/Stephanodus pharyngeal tooth at 4 cm (those two specimens in that TFF post aren't 4 cm).  So a pycnodont pharyngeal tooth from a large species that we just don't see here in the US.

Yeah, pycnodont seems to be what that is.  Giants exist.  I once saw a Paraorthacodus tooth that was about one-third larger than any other one I'd seen before.  And what about Northern Shark's giant Carcharoides tooth?

 

The other specimen might be a piece of another one though it seems flatter so that might be a piece of a sawfish rostral spine.

First thing I thought of was Eotrigonodon (E. serratus occurs in the Lede Sand Formation, in the Eocene of Belgium). 

The exact shape doesn't fit with E. serratus but I could see it going with maybe another Eotrigonodon or another closely-related fish. 

 

Even though it's giant in size, I'm still sticking with fish pharyngeal tooth.

The Eotrigonodon is not a pycnodont, it's from the Tetraodontiformes. Perhaps that's another place to look at for a genus/species answer for this specimen.

Am liking that you've said "definitely not just a rock". We get a lot of "just a rock" IDs here on the forum but hope that no one would say that for such a distinctive fossil.

Agree with Al Dente on the ID.
