Not sure what this is can anyone identify?

Not sure what this is could not find my measuring tape but am estimating it to be about a little longer than an inch.

Sorry this was found in a gravel pile brought in from the Brazos river here near Houston Texas....I had tried to print the measuring paper for a more acurate measurement but my printer don't seem to be working.

Interesting and suggestive shape, but I think it's stone.

The crack seen in the top left photo reminds me of the way enamel on a shark tooth sometimes breaks away, and the texture seen on the end could be a fit. The shape might not be a coincidence.

looks quite symmetrical. No idea what, but I am in the fossil camp.

I really don't think what to think about this, because it looks to have a deterioded enamel and has the right shape for a tooh, though, it has no serrations visible, so, i just can't choose sides.

Looks like a fish bill . . . that is, from a billed fish . . . like Protosphyraena in the Cretaceous and other possibilities if Eocene to Miocene.

OR . . . It might be the tip of a bone pin, a NA artifact.  Is it, in fact, mammal bone?
