  1. Six Amazing Dinosaur Fossils

    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/
  2. Tooth?

    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. :-)
  3. Opal bivalve ID requested

    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!

  5. Theropod from Australia?

    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!!
  6. Opal ammonite?

    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?
  7. Opalized Vertebra?

    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.

  9. Opalized gastropod?

    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.
  10. Belemnite Squid Fossil

    Thought I would share this new piece we just got. Belemnite is fossilised squid over 100 million years from Coober Pedy, South Australia. Photos:
  11. 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
  12. Is this a opalized vertebra?

    Is this opalized wood or possibly bone? Anyone seen this before?
  13. Opalized Wood?

    Can someone please tell me, is opalized/petrified wood actually fully replaced by opal?
  14. Petrified Wood Arizona Ranch

    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

  16. 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
  17. opal fossil, what is it?

    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
  18. Beautiful New Species of Dinosaur Preserved in Opal!

  19. strange center in pebble

    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?.
  20. lightning ridge fossil

    Hello would this be some opalised bone and could be from a dinosaur or some marine reptile ?
  21. Opalization?

    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)
  22. 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.
  23. I know this is not a fossil but I need help with identifying the rock
  24. What kind of rock is this?

    Its very reflective in the light the other images are used with flash on the camera so it does not capture the reflectiveness
  25. 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!!
