Find your nearest monumental masons or high end kitchen fitters. Both should have equipment to cut/polish stone. Get them to cut and polish some half inch slices, see if you've got some nice grain/growth rings preserved.

Jeez it must have a terrible fright to become so petrified....LOL.
We often find bits of petrified wood out the bush around here too since a lot of this area was once under the waters of a very ancient, shallow sea millions of years ago.

As you probably are aware Arrow living in NM as we do, its not uncommon to find petrified wood all over New Mexico and Arizona. As the Mesozoic seas retreated on either side of the Rocky Mountain complex, large swaths of shallow marshes persisted as the inland ocean retreated.
