Thanks for the kind words. I have another piece that is about twice as long but a lot of the charcoal exterior has fallen off. Which leads me to my other question. I would like to keep it looking like it does but the charcoal layer is pretty fragile and falls off easily. With it being as fragile as it is there any suggestions for stabilizing it? Possibly some CA glue? Any other ideas?

I would flood all cracks with superthin CA glue. it wicks in better!

 I doubt pet wood fires produce much heat, so it had to burn before petrifying, and it burned on all surfaces so it was most likely standing during the conflagration that was just surface material. Why didn't the coal agatize? forum.rocktumblinghobby.com/post/729955/thread#7. 92 Ma - JET - Petrified (Coalified) Wood. “Jet is a product of high pressure decomposition of wood from millions of years ago, commonly the wood of trees of the Araucariaceae family. Jet is found in two forms, hard and soft. Hard jet is the result of the carbon compression and salt water; soft jet is the result of the carbon compression and fresh water.” During the 15th and 16th century it became fashionable to give Mourning Jewelry of black and white stones to relatives of the deceased Mourning jewelry made of Jet (182 million year old early Jurassic, from Whitby, North Yorkshire, England) reached its height of popularity in England after the death of Prince Albert in December 1861. Queen Victoria went into deep mourning, which was imitated by her subjects when faced with their own bereavements. Jet jewelry made a comeback with all the flu deaths and the first World War in 1918, and was adopted by the Flappers of the 1920's. In 1916-18 Tiffany & Co of NYC heard of Jet being discovered near Hanksville Utah and purchased most of the entire production until supply finally overran demand in 1926. In Utah it is found in two Cretaceous Rock Formations, The Dakota Sandstone and the Straight Cliffs.  |

I will read through it and see what I can figure out. |

That is really cool! It seems like it had to burn first.

It looks like you can see the burned bark even on part of it.
But maybe I'm just imagining that.

Really cool. Hopefully more to be found in the adjacent area.

Really cool. Hopefully more to be found in the adjacent area. I found it on the edge of a river. I am sure more will get exposed as the banks erode. It is illegal to dig for petrified wood and fossils where I am from. You can however surface collect so I will have to wait for Mother Nature to expose it. We have good runoff water levels happening right now so plan to go look in a few weeks when levels come down and see if anymore is exposed. |

Yes that is coal around the outside. I have seen it many times in the coal mines of TN, KY and WV. One thing to note is before you drag that into your basement make sure the yellow colored edges on that are not radioactive. Carnotite (K 2(UO 2) 2, (VO 4) 2·3H 2O) is a common uranium mineral that is associated with pet wood. This can cause radon. Keep it in a well vented area. Is the wood agate replaced or sandstone?
What state is it from?

One thing to note is before you drag that into your basement make sure the yellow colored edges on that are not radioactive. Carnotite (K 2(UO 2) 2, (VO 4) 2·3H 2O) is a common uranium mineral that is associated with pet wood. This can cause radon. Keep it in a well vented area. Is the wood agate replaced or sandstone? What state is it from? Good to know. It is from Alberta, Canada. Will have to try and find a detector to check for radiation. I have seen the detectors at work when they check down hole equipment for radiation when it comes out of a well. But I don’t know anyone that would have one on hand that I could use. Is there another way that you know of to check for radiation? So you think the outside layer has turned to coal and the inside has petrified? You don’t think it is possible that the outside of the tree was burnt before being buried and petrified? These are just questions as I am trying to learn. I have not cut a piece but I don’t think the inside is agatized. |

It is Upper Cretaceous. I believe Dinosaur Park formation from what I can tell for that area. ~ 75 million years

lorney probably not burned. Take to university they may be able to tell you/have tools to determine carnotite.
