Zoly55 Posted July 16, 2016 Share Posted July 16, 2016 I found about 10 miles outside needles, CA in a dry river wash were I was looking (and sucsefull) in finding tons of petrified wood (will attach those pics as well). Please let me know what you think it is and if it is worth authentication at Arizona university or something like this.

JohnJ Posted July 16, 2016 Share Posted July 16, 2016 Some rocks weather differentially; in other words, some parts wear away and other parts stay. This is an example. It is not a petrified mushroom or anything else. (Topic title edited. Anyone replying to this topic, please keep in mind the "family oriented" nature of TFF and our guidelines. Thanks. ) The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
JohnBrewer Posted July 16, 2016 Share Posted July 16, 2016 A weathered rock I think rather than a fossil, but interestingly weathered. Definitely a keeper! John Map of UK fossil sites Link to comment Share on other sites More sharing options...
DPS Ammonite Posted July 16, 2016 Share Posted July 16, 2016 Welcome to the forum. It is not a fossilized mushroom just a suggestively shaped rock. Nice petrified wood. What formation does it come from, Miocene Bouse? Do you find any petrified ironwood? My goal is to leave no stone or fossil unturned.

Zoly55 Posted July 16, 2016 Author Share Posted July 16, 2016 @dps-amonite....the wood is about 80% iron. Some of the heaviest petrified wood I have found. Why do you ask about the iron content? Link to comment Share on other sites More sharing options...

Some of the heaviest petrified wood I have found. Why do you ask about the iron content? If it had that much iron content it would be magnetic. Most petrified wood is quete heavy-- relatively speaking. Iron wood is a type of species of wood and not a reference to what it is made of. Tony PS Welcome to TFF!!

Zoly55 Posted July 16, 2016 Author Share Posted July 16, 2016 http://m.imgur.com/a/46TWk Does that help any? I will go check the magnetism now. And yes it was in Miocene Boute formation! Link to comment Share on other sites More sharing options...
DPS Ammonite Posted July 16, 2016 Share Posted July 16, 2016 I was not referring to the iron content of the wood. I have seen large pieces of fossilized ironwood from along the Colorado River in Arizona that looked like real wood from a few feet away. My goal is to leave no stone or fossil unturned.

Zoly55 Posted July 16, 2016 Author Share Posted July 16, 2016 Slight magnetism in my opinion from the little manger I have. Cannot much feel the magnatism when approaching the rock but when you remove the magnet you feel a bit of a tug. Link to comment Share on other sites More sharing options...
Zoly55 Posted July 16, 2016 Author Share Posted July 16, 2016 @dps-ammonite the Colorado river is about 7 miles from this site and their would be no view angle from the river to this site Link to comment Share on other sites More sharing options...

Cannot much feel the magnatism when approaching the rock but when you remove the magnet you feel a bit of a tug. I think You missed the point-- Ironwood is a type of wood, like oak, pine, cherry, etc.... It is not wood made of iron. It would be very unusual for wood to be replaced by iron.

Zoly55 Posted July 16, 2016 Author Share Posted July 16, 2016 It's quite common. All the black in petrified wood is iron oxides. Know I understand it's the commen name for a tree species ironwood Link to comment Share on other sites More sharing options...
ynot Posted July 17, 2016 Share Posted July 17, 2016 It's quite common. All the black in petrified wood is iron oxides. Iron in petrified wood? Yes, but it is only small trace amounts, not enough iron there to cause the fossil to be magnetic. And no, there are many other minerals that cause black in petrified wood.

Zoly55 Posted July 17, 2016 Author Share Posted July 17, 2016 For example ynot? which minerals inside (saturated) into quartz can contribute to black inside petrified wood? Link to comment Share on other sites More sharing options...

ynot Posted July 17, 2016 Share Posted July 17, 2016 For example ynot? which minerals inside (saturated) into quartz can contribute to black inside petrified wood? Carbon, manganese, magnesium and I can not think of any more right now. (iron is more likely to cause yellow to red colors in petrified wood with silica replacement.) The coloring agent is deposited with the replacement mineral as the wood is being replaced, and can be very small amounts (1 part per billion). The material does not have to be saturated. Also-- not all petrified wood is replaced by silica (quartz). Slight magnetism in my opinion from the little manger I have. Cannot much feel the magnatism when approaching the rock but when you remove the magnet you feel a bit of a tug. Are You saying that the magnet will stick to Your rock? If not the rock is not magnetic. Tony 2 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."
