Okay so now that I have found a group of individuals to help me identify.... I would love to know what find of petrified wood I have collected.. species and mineralization would be helpful. I have stuff that I can't find online. I'll start with the first two that I can't even tell if they are wood or not... All help is incredibly appreciated. Found these two river tumbled pieces south of Green River, Utah. Jurassic I think? Very different from everything else in the field.. Looks agatized? Thank you! Trenton

I've seen a lot of opalized fossils but none exactly like this so I was wondering if anybody could help me pinpoint exactly what it is and if it holds any value? The specimen is roughly 25 mm, semi translucent and has a fair amount of color.

I have found a burned petrified and opalized tree buried under a hundred feet of basalt with plenty of mineralization. I am trying to find out where i can have it identified and appraised. Thank you for your help. This was found in the northwest United States in the Colombia river gorge in Oregon.

Hi all! Just got back from a weekend hiking along the Olympic Peninsula oceanside beaches with my family. I usually pick up a few beach stones on trips like this, and his particular stone caught my eye because the lighter colored streaks sparkle a bit in an opal-y kind of way. When you hold it to the light you can see a pretty clear wood grain/ring pattern, with the opalized bits filling where you might imagine cracks in the wood to have been. I know this is hard to be sure from photos but just curious if others agree that this appears to be petrified wood.

I was wondering a few things about opals effect on fossils and bones in general. 1) does it degrade the value? 2) how long does it take? 3)how does it work? 4) would I be able to do it to some spare animal teeth? (Hope that’s not weird haha)

Hi all, here is a piece of snakewood (Menningoxylon) I found in a river, from the Whitsett Formation-Oligocene exposed, aprox. 34-35 million years old. It is completely opalized. Order: Caryophyllales Genus: Mennegoxylon (unranked): Angiosperms Kingdom: Plantae For your viewing pleasure.

When considering the permineralization/replacement processes and how they affect wood.And all of the organic material in and or around the wood.In clear to opalized voids in the tree sections what other organic material has been found,beside the wood itself?

Greetings. I was wondering if anyone here could help identify some of the individual organisms in this specimen.. It is a partially opalized bog material. I collected it from an area in northern California that is listed (on USGS Geologic maps) as Eocene nonmarine. I worked this specimen with diamond tools for a bit to better expose the contents. Thanks!

Name: Opalised Belemnite Pipe Age: 120 million years old Locality: Coober Pedy, South Australia Length: 52mm long -
From the album Opalised Fossils
Name: Opalised Belemnite Pipe Age: 120 million years old Locality: Coober Pedy, South Australia Length: 60mm long Notes: This is an opalised belemnite pipe from Australia. It originates from the Cretaceous marine deposits of Coober Pedy and is transparent when held up to a strong light. It is also quite a large example. -

Name: Opalised Bivalve Shell Age: 110 million years old Locality: Lightning Ridge, New South Wales, Australia Formation: Griman Creek Formation Length: 25mm Notes: This is an opalised bivalve shell from Australia. Unlike the marine shells from Coober Pedy, the other hotspot for opalised fossils in Australia, the shells from Lightning Ridge are less common and come from a freshwater river environment. This one is open, and clearly shows the ridged pattern of the shell it once was. A nice addition to my opal fossil collection. -

Name: Opalised Dinosaur (Caudal?) Vertebra Age: 110 million years old Locality: Lightning Ridge, New South Wales, Australia Formation: Griman Creek Formation Length: 16mm end to end Notes: This is an opalised dinosaur vertebra from Australia. I originally bought it as an opalised 'reptile' vertebra but it's ID as being a dinosaur vertebra was confirmed by one of the leading experts on the opalised fossils of Lightning Ridge. It is likely a juvenile ornithopod or theropod vertebral centrum, missing the tall neural arch. It is semi-transparent when held up to a strong light and is an exceptionally rare specimen. So far it is the only vertebrate fossil in my opalised fossils collection but I hope I am able to acquire more soon. Specimens like this very rarely come up for sale as most of them end up in museum collections due to their rarity and scientific value -

Hello everyone I have recently obtained an opal parcel of rough to cut into gems from the opal fields at lightning ridge Australia, however right before I was about to grind this one rough opal something stood out. I remembered walking in the natural history museum in Sidney Australia and noticed the opalized teeth of varies animals/dinos etc. This one was just like one I had seen many years ago. I cleaned it only; no polish just water and a soft paintbrush as not to alter it. From my research, I found a possible match a Hypsilophodon it lived in the area where lightning ridge opals are found and some recorded fossils of this dino are sometimes unearthed there in small pieces. I have tried to contact museums and or universities as I live near OSU and they have one of the best paleontological programs in the country (or so I’m told) and have not heard back after 6 months of trying from any of them. I would like to know if it is a real opal replacement of a tooth or a lookalike. It measures 13.33mm long X 10.9mm wide X 4.02mm thick. And is very detailed under a microscope with tooth like root. Any ideas? I have cut thousands of opals from rough, and have seen millions of pieces of rough easy, including opalized fossils, even some plesiosaurs teeth but never this. The miner, who sold me the opals, said that he has been finding some opalized dino bone fragments lately but they are unidentifiable as they are crushed, and very small pieces, and I also purchased a opalized finger or toe bone from a very nearby find, possibly a turtle flipper bone.
