Auspex Posted September 1, 2014 Share Posted September 1, 2014 I'd put my money on petrified wood; I can make out growth rings and a knot.

tmaier Posted September 2, 2014 Share Posted September 2, 2014 I saw a guy in utah use a sand blaster to blow away the outer oxide surface and it looked really good. You never know what colors are inside till you peek. Then the guy ran it through a table rock saw and the cross section was fantastic. Link to comment Share on other sites More sharing options...
bdevey Posted September 3, 2014 Share Posted September 3, 2014 It looks like fossil wood, but just to be sure give it a light acid test. Use vinegar, pour some over it to see if it fizzes at all, give it a minute and than rinse it, If it fizzes its a calcite flow stone, if not Most probably fossil wood.

tmaier Posted September 3, 2014 Share Posted September 3, 2014 When doing the acid test, you need to bare down and clean the surface a bit before applying the acid to see if the acid is actually reacting with the underlying rock and not with any material adhering to the surface. If there is some limestone on the surface you will get a false result. Link to comment Share on other sites More sharing options...
