    need a picture of the sides. Could be petrified wood, could be just rock layers.

    even if it was shaped, man made objects are not fossils

    Bone with what appears to be cut marks on the sides. Probably modern having been butchered with a knife.

    Teeth with a few exceptions have enamel just like your teeth.

    What I look for first is symmetry and repeating texture. Look at images of parts of living things. Bones and teeth have a natural symmetry. Rocks do not. They are usually irregular in shape.

    Definitely a molar of some sort, however it is modern and not a fossil.
