Trying to find out what this is. Found in the Northern Nevada desert. It looks like a round tree trunk 10 inches across. Half of the outer surface is somewhat smooth and the other half has a stepped pattern that reminds me of how some plants grow stems upwards. The pic that shows this section maybe upside down. The photographer and I aren't sure whats up or down. The texture is like glass, we think its opalized? Very sharp edges and smooth. It's brittle. The color is brown on outside with white calcium patches. Inner area is a solid carmel color with tint of green, there are no flashes of rainbow colors or clear crystals. There are no other patterns, dots, striations, or wood like grain. It was found among volcanic and igneous rock field. Searched for more similar but none found on surface.

So i happen to come across this image, and it claims to be an opalised dinosaur jaw fragment from SA (South Australia) for me at least i do see some kind of fossil but its identification as carinal is dubious in my opion. What do yall think?

Howdy folks, Last weekend I returned to a place in Texas that I have collected marine fossils at previously. The owners of this area have specifically asked that I not share any details on the location, but it’s a bit of an anomaly as it appears to have a number of fossil bearing matrix including sandstone, shale, limestone, and the thickest mud I’ve ever seen. It doesn’t match any of the USGS data either. I found a number of things there that I would like to preset, but the main one is this: The little plates that make up this stone form a spiral and they shine like opal / ammolite. This tear drop shape is something I’m familiar with as I have another one, smaller, that also shines, as well as chert nodules of the exact same shape that I suspect are related. Here are a few other things I collected at this location: this piece of limestone is rather large, about 20lbs, and it’s filled with things I’m not even remotely qualified to ID. It deserves its own post which at some point I’ll get around to. I collected this at the same location years ago. I think it’s an orthocone or pseudo-orthocone nautaloid. Well, half of one at least. Not sure really, but it also deserves its own post.

Hello hello, recently i bought some opal, in amongst the small stones was this. I am wondering if this is a fragment of bone? Maybe a piece of jaw bone? Its from Coober Pedy, which i believe is cretaceous and marine

None of these finds is new, but it is a good excuse to relive six amazing dinosaur finds: https://newatlas.com/science/incredible-dinosaur-fossils/

Hello! If anyone could help me out with this it would be appreciated. This opal replacement fossil was mined in New South Wales, about 6 years ago. I found it in a parcel of Lightning Ridge rough and have been trying to identify it for a while now. The closest I have come to a positive match (Still not a match but it's close) is the Molar of a giant Marsupial from the order Diprotodontia. There is a wee problem with this, I've read Lightning Ridge Opal is supposed to be from the Cretaceous and Jurassic periods, a minimum of 66 million years old. The Diprotodontia existed throughout most of the Pleistocene, about 63 million years off. HELP! Thanks in advance everybody. :-)

Hi everyone, I have this opal bivalve for around a year now I think, but I didn't really bother to look for an ID before. But I recently ordered an opal belemnite so I am thinking on making some new ID cards and I would like to make one for this bivalve as well The bivalve was found in the Bulldog Formation,Coober Pedy, Australia (Early Cretaceous, 135 mya) I am not sure if the photo's are clear enough, but it is the typical bivalve you see often from Coober Pedy, just can't find anything on them. Thank you in advance!

Hi I found this online and am wondering if its a tooth?, or just a piece of opal. Its 2mm, and is from Lightning Ridge Australia. Thanks!!

Picked this beauty up at a local pawn shop over the weekend. I have no experience with opalized fossils, but it looks to be an opal ammonite to me?

New possible acquisition but need more info. This was obtained in a trade and originally from Lightning Ridge Australia. It was claimed to be dinosaur vertebra but who knows? It is still unprepped and has matrix that needs to be removed which will further improve the look. Two piece, one is 1.5 inch and the second is 1 inch. There are sections where it looks like the fossil did not completely opalized. Any thoughts? @Troodon - help? Thank you all.

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.

Thought I would share this new piece we just got. Belemnite is fossilised squid over 100 million years from Coober Pedy, South Australia. Photos:

Hi Everybody, I am trying to ID some fossils for my friends from the Royal Peacock Opal MIne. They have these fossils for display only at their gift shop but they are not really sure what they are. These are all miocene age fossils, Humboldt County, Nevada. I think the foot and the teeth are from some kind of small horse. I have no idea about the jaw with the teeth. Picture 1: Articulated foot bones from a horse? Picture 2-4: Jaw section from unknown mammal Picture 5-6: Bovine tooth, horse? Bison? camel? Picture 7: Bovine tooth, horse? horse? Bison? camel? Any IDs would be appreciated, Thanks, Jesse

Is this opalized wood or possibly bone? Anyone seen this before?

Can someone please tell me, is opalized/petrified wood actually fully replaced by opal?

Well hello everyone it’s been a while for me as it’s been a rough couple of months Traveling to be with my late Sister who battled to the end with Pancreatic Cancer. So I crossed off three of her bucket list adventures she wanted to do in our return trip to Texas. She wanted to find a Sharks Tooth, a snail ( Gastropoda) and dig for Crystals. Well as as I said we just got back from a two week stay on the west coast and the weather was not very good to us. But our first stop we had arranged to dig for Petrified Wood on the Dobell Ranch. Well when we got their to our surprise nobody was around and everything was closed up. So I called to ask what happened and the owner was very sorry as the Tucson Fossil and Minerals Show was in action and she had to delivery a tree they dugout a week ago and forgot about us. Well long story short she said no worries just go and start looking!!! So guess what we did!! i was looking for smaller pieces for my jewelry making and I found about 25 pounds of nice material. I also found some Rainbow petrified wood which made the trip worth it!! Pictures to follow as I have to crop them and cleanup the pictures to fit and download

I saw some beautiful opalised fossils in An Australian museum and I was just wondering if it is possible to acquire one (without huge funds) even if that is not possible it would be nice if anyone has them if they could show themthese at the ones I saw in the museum

Hello All, I was hoping that someone could help me identify this bone? its from the mid-Cretaceous Griman Creek Formation of Lightning Ridge Australia I don't think its a yabby button or turtle shell, as the piece is not rounded like a yabby button and there is bone texture. the piece is bilaterally symmetrical and there appear to have joins or groves where the bone meets. The underside is not flat like I would expect for turtle shell... Looking forward to your replies Rod

found this this morning... any ideas...fossil?...Opal?..animal mineral or vegetable?..jellyfish?...open to suggestions? I was leaning toward possibly chocolate opal but the weird things in it have me stumped...is it some type of fossil? if its not a fossil and is opal never found one before...the whole stone is about three quarters of an inch with the center only just over 1/4 th of an inch. found in our gravel drive in texas...but really it does not look opal so was thinking fossil of some type?.

Hello would this be some opalised bone and could be from a dinosaur or some marine reptile ?
-
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)
