the first one looks like normal un petrified driftwood, the second which one looks petrified. You can tell it's wood in this case easily as you can see the growth rings on the ends and the wood grain on the sides, bone does not have those rings and has a specific porous texture about it.

someone else will have to provide more detail as i am not qualified enough :)

I have collected many pieces of petrified wood from different places...wondered that myself. I would guess there are many factors...type of deposition, what minerals are replacing the organic material, etc. Lots of wood, all different from one another. I have a piece that has been replaced with copper related minerals...very heavy for it's size!

Bone structure is vastly different than wood. When I first started, I used the tongue trick quite often...over time, I began to "see" it. Once you see the two side by side, you begin to better understand.
