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

Beautiful New Species of Dinosaur Preserved in Opal!
Thecosmilia Trichitoma posted a topic in Fossil News
https://www.nationalgeographic.com/science/2018/12/exclusive-sparkly-opal-filled-fossils-reveal-new-dinosaur-species-paleontology/ For all of the members here who love both minerals and fossils. -
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)

I used to be a member her many years ago when young Knackers McGee started the site showing off his wonderful finds, time marches on, now i have somethig to contribute of note. I aquired a collection of Gem grade Opalised Plesiosaur bones, mainly half verterbrae, whatsit called, split vertically. Included, was one unknown perfect split shown below. If anyone is interested in such things, I can post more pics and links to videos for your amusement. This image is of the best split, most likely broken in the field by the pick. The central inclusions are very shallow. I could not believe my luck as the person who sold then to me did not recognise the bones in the parcel. Sadly I did not buy all of it, so there is or are people out there with half a dozen matchng halves to what I have. Some of the pieces have great detail of bone structure on the outside, some look to have internal passages preserved in great detail. Veins or ateries not opalised within the Opal. All very rare to find as ordinary fossilised bone, opalised is very very rare.

I know this is not a fossil but I need help with identifying the rock

Its very reflective in the light the other images are used with flash on the camera so it does not capture the reflectiveness

Opalized Ammonite - Real or Fake, help!
ewecollector posted a topic in Is It Real? How to Recognize Fossil Fabrications
I've recently bought this fossil from a seller on Instagram and these are the seller's pictures, but after some recent digging, I was introduced to the reality of counterfeit and fake ones. Does this one look real or fake? The seller doesn't have location of discovery and I've been trying to google how to learn whether it's real or fake but I haven't gotten far. Thanks for your time!! -
Hi all, Recently saw an opalized ammonite out at a rock and fossil shop in Colorado. It was really quite beautiful but as I'm pretty much an amateur when it comes to identifying fossils, I have concerns about its authenticity. I'm wondering if anyone can give tips on how to spot fakes. thank you!

Dear paleo experts, I wonder if you could help me out here. Please excuse my naivety if I have totally gotten this wrong... but I am wondering if this slab of opal (Lightning Ridge, Australia) in my collection might actually bear the imprint of some fossilised material? It was the very informative blog of Andre Stucki (opalised fossil specimens) and Johno's Opals that brought me here to seek your advice. Thank you for any information you might be able to provide. And if I am totally wrong about this; my sincere apologies for wasting your time.

Attached are photos taken of a stone sphere (~ 50mm in diameter) I recently bought from a local store. The vendor told me that it was made of a mineral from Western Australia. In fact, the features in the sphere are quite mysterious. Is it a ball of a frozen scene of lives that were crowded and were busy in reproducing in a time in the past?

From the album Adventure is an individual thought!
These are the most unusual chalcedony forms to find in the World. Here is one laid upon some pine needles. Some spots will have so many, you will have to pick only the most interesting ones! Have a collecting bag around your neck to put them into it. Have a walking stick to hike with, do some prodding in thick pine needles. We have seen some rattle snakes, actually one, but it was nearly five feet long a Basalt ridge. Just be aware. Wonderful camping. Well maintained roads. Gasoline, groceries and water to be found in Reserve. On a map draw a fifty mile circle and you are just beginning to find places to hunt. Most are to the north, east and west of Reserve. The locals will help you figure out where to begin. -
From the album Adventure is an individual thought!
This is a typical flat to find loose chalcedony. There are areas of Basalt and Rhyolite that you will find the sources of all of the agate and chalcedony. Once you understand lava flows from the Oligocene volcanics... you are on your way to finding the most unusual chalcedony in the world. Step into a Forest Service Office, get the large scale Forest map(s) you need, inquire as to where a good area to begin looking might be... and you are on your way. Make sure you mark where you camped... so you can find it next time and finish looking over the beautiful hillsides. -
From the album Adventure is an individual thought!
Have your dogs pack the water into the back country and pack the finds back to camp. There are so many areas to find agate and opal that you just find a nice camping spot and begin to prospect by walking... and walking... and walking. Even "Apache Tears" can be found north of Snow Lake. Bring a bag to carry them. These are the size of a dime to quarter. The dry creek beds and hillsides are a good place to start... north of Snow Lake are some nice camping spots and the hills further north have the Apache Tears washing out in the dirt roads! -
From the album Adventure is an individual thought!
Reserve, New Mexico is the center hub of agate hunting. Luna, New Mexico. Apache Creek, New Mexico. A thousand square miles of the roughest terrain in New Mexico. Bring a GPS so you do not get lost. Go further south to Glenwood Springs and check out the mining districts. Silver City and the copper mines are not too far away. Visit the Gila Cliff Dwellings. Worth the drive.
