Is this a tooth and if so, of what?

[Carl31]

This is a tooth? I found over fifty years ago and I don’t remember where.  Picked up all kinds of things then..

I lived close to Palo Duro canyon in Texas at the time but often looked for fossils  and rocks in Az, Nm, Co,Ut. On summer trips.

the length of the item is 8.5-9”, diameter 2.5”.  Insides possibly  looks like dentin.

New to forum so please excuse any mistakes I make, and thank you.

Hi, sorry, that's not a tooth. It looks like a piece of flint, the lines would be the result of a fault mirror.

Not a tooth - no enamel, and no bone/root material.
