  1. Since the spring my wife and I have been very busy with the garden and the orchard to maintain, the canned vegetables from our production, and we decided last Thursday to take a break for a geological excursion south of Clermont-Ferrand. The goal was twofold, to search for stromatolites and to take advantage of the volcanic context of the region. The detailed geological map of this area is unavailable but we had serious research ideas for our prospecting. The day began with a visit to a magnificent village that immediately immersed us in the context: Saint Saturnin. The walls
  2. I posted pictures of this uncut stone/fossil several weeks ago hoping for an ID, but since I didn't know the location it was found, the consensus was it most likely is stromatolite. I've had it cut and polished and it's gorgeous! It's very dark inside. The circular parts look like they are gray and black, but in real life it seems to be just 2 different textures of black. The parts that look more gray are rougher/grainier and the blacker areas are more smooth and reflective/shiny. The circular parts almost look like fluffy clouds. The in between area is dark gray until you get
  3. Hi, I bought this at a flea market in McKinney, TX about 8 years ago and am trying to get it identified. The person selling it didn’t have any information on where it was found or what it is. I took it to a local rock shop recently to see if it could be ID’d. The owner is more skilled in minerals, but he thought it might be a fossil (stromatolite), and recommended I reach out to someone skilled in fossils to know for sure. Magnets do not stick to it at all. I found a small seashell attached to it, but nothing else on the outside. It’s a rounded triangular shape. Measures about 8 1/2” (32
  4. I am heading to Herkimer for a trip soon, and I was wondering if anyone knew any places one could find fossils? I heard some of the mines have stromatolites but I could not find much information on that. I also hear about trilobites near the diamond mines, and I hope to find some, and if anyone has any advice that would be appreciated.

    Stromatolites

    Two highly polished, end cut Stromatolite agate achats from the Mátra mountains, Gyöngyöstarján, Hungary from the Miocene, 20 million years ago that I recently purchased. These are the first Stromatolite fossils that I’ve added to my fossil collection. I’m posting a few pictures to show the incredible colors in these pieces. End Cut (1) ( 543grams 103mm by 102mm by 35mm) End Cut 2 (166grams 75mm by 45mm by 45mm)
  6. Not sure what to make of this, came from mix of Cretaceous and QAL, breaks very easily. Thinking it's sedimentary but then wouldn't it be harder?

    Cambrian Stromatolite

    Got the itch to collect and study some stromatolites, so I did some searching and feel that I successfully scratched the itch. I found a section of the Cambrian Copper Ridge dolomite that exposes a plethora of stromatolites of various morphologies. Many of them look as if they are straight out of Shark Bay in Australia, with the characteristic domal structure attached to a thinner holdfast on a hard substrate. Stromatolites are formed over a long period of time in tidal zones by colonies of photosynthetic bacteria and/or algae that form sticky layers that trap sediments and concrete them into
  8. I have seen this for sale online Seller got it from an old collection and has no provenance info. He has no idea where it was collected or formation info is this some sort of geological formation ? Or is it a genuine Stromatolite ?

    Miocene Lacustrine Stromatolite

    This silicified lacustrine Miocene stromatolite is a trace fossil made by a gram-negative photosynthetic blue-green bacteria. The originally limestone stromatolite was formed as a bacterial mat trapped sediment and precipitated limestone as it grew from the lake floor towards the sun. It shows classic convex layering towards the top. The stromatolites occur in tuffaceous and lime rich lake sediments that might be part of the Chalk Canyon Formation that is bounded on the bottom by basaltic lava and volcanic rich conglomerate and sandstone on the top. Locally numerous silicified cast
  10. A friend cut a polished a silicified lacustrine Miocene stromatolite from central Arizona that I found. Thanks Stan C. It is about 8 inches in maximum length. Two faces were cut that show the upward convex growth. I am currently looking for a researcher to help write a paper about these and the other plant fossils that occur in the area. A piece that was cut from the same colony as this piece is being donated to the Pinal Geology Museum in Coolidge, AZ. https://pinal geology museum.org Another Arizona museum wants one. I am seeing if other local ins

    Texas Stromatolite

    From the album: Miscellaneous

    Found in the Red River/Lake Texoma. Likely from the Cretaceous-aged Paw Paw Fm. ~ 100 Ma.
  12. I went to the aquatics shop this morning to buy some fish food. They were selling these rocks as decor. Person helping me had no idea re provenance. I think they are geologic in origin. But with the banding was thinking there is an outside chance they could be Stromatolites About hand size.

    Help please.

    Hi, I found this stone in...a charity shop. I really love it but I’m not sure what type of stone it is and the only one I can connect it to would be stromatolite. It has more unusual pattern though. Please could someone help me with identification. It has a clear quartz (I think) in the middle, it should be visible on the photo. Thanks

    Stromatolite ID help

    Hello all, & Thank you in advance. I was wondering if you could help me ID this Stromatolite species or location it could be from, it was a random buy & fair price, though it was only labeled as a Australian Stromatolite. I've looked at a Australian dealer that sells a wide range of AU stromatolites. I'm not coming up with a clear match that says this is it, I know stromatolites can vary some to a lot in a species & locality. Australian or some other location around the world ?
  15. Hi I was wondering what your opinions are on these if they're real or fake, or any work done on them ? There's two of them. Labeled as - Lacustrine Stromatolite colony's, no work done on them. First - from the Permian age, Lauterecken formation, Germany Second - from Oligocene age, Rhineland Germany

    Strelley Pool Stromatolite

    From the album: Miscellaneous

    A section of a stromatolite from the Strelley Pool Chert, Western Australia. Currently, these stromatolites are among, if not the oldest known fossils. There is possibly earlier evidence of life in the form of biogenic carbon, but this chert produces the oldest known mineralized preservation of organisms. Of course everyone wants to find the "earliest life," and it becomes difficult to differentiate between microorganisms and geologic structures in rocks so old, so there will always be disagreement and competition. Likely, there are older fossils already found or yet to be, but it requires a l
  17. Hello again Fossil Forum, Last week I posted a few pictures of what I thought might be fossil wood that I found on my property in Southeastern PA (Montgomery County, just over the Philadelphia County line). It seemed that it was possible that my rocks were fossils, but also maybe not... One helpful user suggested that I might polish some of the ends (hopefully crossections) of a few pieces. So below and in the next few replies I will post some pictures of a few pieces, for the polished parts I used a cabbing machine. I live at the bottom of a relatively steep hill and these pieces wer
  18. Hi everyone Surface find in SW Arizona that I would like to ID if possible. I believe this is Stromatolite and it appeared to have a shark, Ray or Skate egg sack on it so I brushed some synthetic oil on it and put it under the microscope. looks like something inside there to me. My first thought is Xenacanthus although whatever that is in there doesn't really match up that well. Complete newbie here asking is this Stromatolite ? and what is that in the egg sack ?. Finding Graptolites, Arthropod's and Stromatolite in the same areas.
  19. Stromatolite? Found in Silurian reef. Thanks for any help..

    stromatolite??

    I found this a while back, and now I'm wondering if it could be a stromatolite. Though, it could just be some sedimentary formation. It was found in the red river/lake texoma in texas. Any thoughts or insight would be much appreciated, thank you! In the second photo, I sanded a bit of the side to show the layering.

    Paleozoic algal matting?

    While hiking through a desert area just southwest of Tucson, AZ. I found these interesting layered rocks. Over the course of an afternoon I came across a couple more spots where these types rocks were strewn over relatively large areas. Many of the pieces would fit inside a square inch or the palm of your hand, while many others were a few feet long/wide. I showed these to a local geologist and he called them stromatolithic Paleozoic limestone – evidence the area was once covered by water and these represent the layers of algae, probably in the form of algal matting that existed there, dat

    Sponge? Coral? None of the above?

    Found in northwestern New Mexico in an Upper Cretaceous area. Specimen was wetted with water to bring out detail.

    Central Missouri

    Found a few beautiful pieces in rocks dug up by the local water department.surface exposure is Gasconade dolomite so i assume these are actually late Cambrian. But im not sure how deep in the ground they came from. Either way. I love these rocks and thought I'd share them with you. A lot of the pictures are different angles of the same rock. But theres a few of a second rock. I think i found and cleaned 4 rocks. Just didnt get pictures of all of them. Hope you enjoy. Happy hunting.
  24. I have been unsuccessful in getting information about this on the general internet (the All-Knowing Google failed me, AGAIN! ). How in the world can you tell if a rock that you have in hand is a stromatolite as opposed to just a rock with striations- like agate or something? Especially if the stromatolite has had a section cut and polished?
  25. Superficially, this beauty looks just like the pics of live ones from Shark's Bay, Australia. Central Pennyslvania, USA
