B&W - Petrified Wood

I took this picture of a large piece of petrified wood.  It is a very large tree stump that likely measures 3 feet across.  It had this little green plant growing in the middle.  This circle shows the plant in the center.  The other is the side as it is probably 18 inches high.  I thought these shots had enough contrast to convert to black and white.
