I found this in a pile of stones we got delivered.
The stones are from a layer before sand come. Around 7 meter down.
Is it petrified wood? 
Hard to tell from the images.
It looks like it could be petrified wood. It also looks like it could be weathered sandstone, or other layered sedimentary stone. Other than testing its physical properties, another way to determine if it is petrified wood vs, sandstone, is to smooth one side where there appears to be grain, then try to polish that side. If it fails to polish, then it is not petrified wood. If it polishes, use magnification to get a better view of the grain structure. From there, compare the structure to known examples of petrified wood.

Hi I thought the same thing I have seen petrified wood that looks the same as that and weathered sandstone
If you have a diamond saw just trim the end off of it you will soon tell
