    Home Conodont Extraction

    So, in trying to identify my local limestone for sure, I've gotten the need to try to extract conodonts, and I'd for sure like to see other microfossils. I know this has been discussed here before, but I was wondering what might be the correct or tried and tested method for home, using obtainable chemicals. The last thread I found was talking about lab processes and clouds of white smoke. I've heard different things from using acids (Vinegar), Hydrogen Peroxide (3% limit at Walmart), to Kerosene. Also a need for sieves, filters, etc. Curious for a guide or advice for ef

    limestone shelf

    Hi. Found among the huge limestone layer at the Caney River in central Washington County, northeastern Oklahoma. Pennsylvanian. It's a little closer to Kansas than to Tulsa. A few miles east of the Osage Hills (or Rolling Hills of the Osage, depending on the which map).

    Mississippian fossil, Arizona

    This little thingy was in Mississippian Redwall limestone in central Arizona. It was in a section of the Redwall with very few other fossils. It's about 10mm long and 7mm wide. What do you think?
  5. One of the nice things about being on the team to design a new facility is you can get what you want. All retaking walls and benches are locally quarried Stoner Limestone from Weeping Water, Nebraska. I can’t wait to get my scribe and chisels out...
  6. I'm looking for assistance identifying a large fossil that was in with skids of limestone rockery from the Niagara Escarpment. I have uploaded a series of pictures to Flickr https://flic.kr/s/aHsmTVvrFN and attached one image. It looks like a type of coral. There is lots of texture on the surface. When opened up, it is full of long columns. Thanks.

    Help with fossil ID for kids

    Hi, I hope this is ok to post! Whilst out on a walk we came across the attached fossil. Whilst I appreciate it doesn't seem much, its quite distinct and any help to identify it - and help educate the small hands which has been carefully cleaning it - would be very much appreciated. I might have some explaining to do that it isn't a t-rex We are located in Derbyshire, United Kingdom. If anybody has good references for teaching kids (6 year old and 3 year old) about fossils it would be great to have them.

    San Antonio, Tx I pulled up a piece of sediment from my yard and this came loose also. I have no idea what it is. I have another rock very similar but much larger.

    Fossil - Trilobite?

    Hello all, Im very new to this. Currently I'm in Czech Republic and some time ago i found my first interesting fossil in this area: https://www.google.com/maps/place/Český+kras+Protected+Landscape/@49.9290996,14.178056,13.17z/data=!4m5!3m4!1s0x470ba30d37e892c5:0xd582af42389f3a3b!8m2!3d49.9355334!4d14.1819469 I don't have any background in palaeontology and decided to get some help from enthusiasts with experience. It's one rock. The main Fossil on "top" is that Trilobites tail? What are those yellowish formations visible on the side of the rock? They stand out a

    Multiple Pecopteris Ferns

    From the album: Missouri Plant Fossils

    When this came out of the earth I was shocked by how many were bundled together as I mostly find only fragmentary pieces of one specimen. The small limestone chunk on the left is a piece that came undone at the site I found this fossil at. More images of these fossils: https://imgur.com/a/KnjIeqG Correct id by Fossildude19
  11. Hi all! Perhaps this is a dumb question, but I' still new to the forum as well as the hobby itself, so I offer a teaching moment - In round rock, (just north of austin in central texas), I have a location at the base of a limestone cliff where after some gritty mining efforts I've come across an extremely dense pocket of what I've been informed are internal casts of rudists. That ID was great!, but I'm having trouble learning about what the actual organisms were like. I've tried researching quite a bit with no clear picture of what these are that I'm discovering. Also geologic maps
  12. Time Period: Pennsylvanian Location: Missouri Formation: Most likely Winterset limestone Hello! I am currently puzzled on weather or not this is a Conodont or some fragments from Brachiopod. I am thinking it could be broken parts of a shell or broken pieces of a Brachiopods fossilized lophophore supports from a very small specimen! I have not found any conodont specimens from this location yet as I usually do not hunt for them Images in natural file size: https://imgur.com/a/KNeq

    Unknown Fossil?

    I found this in an area of North East China. The area has some volcanic history, and a lot of granite mines. I thought that I had it figured out, but am torn on what type of limestone it is, thus what era it could have formed during, thereby leaving me clueless about the small, potential fossil! Any help would be appreciated! Also, any clues on how the granite became fused to the limestone?

    Pentagon shaped piece

    When cleaning up rocks I brought home today, I found this little piece that I didn't originally target. It's pentagon shape makes me believe it's for sure a fossil. I've never found anything like it, so I feel like I'm about to get an education here. Perhaps part of a crinoid? Whatever it is, I don't have the experience, yet. Also noticed the indented hole on the top. Maybe part of it, maybe not. It's way too centered I think to not be part of it. Underside. It is convex with a small raised ridge along the edge. Sideways view of the

    off the CA coast

    A firend of me sent me this pic of cobble stone he picked up on the seashore. The only thing I could tell are the gastropods. What else are there? Possible ID and age?
  16. Me and my boyfriend went for a walk in the nearby Aristide and Silverdale area of outstanding natural beauty a few weeks ago. We are both at uni in Lancaster so have been enjoying walks in the Lake District and nearby. I wanted to visit Jack Scout as a dissertation topic I was thinking about was related to the local geology of the area. I was not expecting to find loose fossils, and was paying close attention to the limestone rocks and pavement for fossils in situ until my boyfriend came up with a ‘funny rock’ to check with me and lo and behold, an impromptu fossil hunt began. Nothing is of g

    Fossil antler pieces?

    Can anyone help me identify these? The longest is 5 1/2”. Maybe deer antler pieces?

    Nodules in Redwall Limestone, Central AZ

    The photo shows several nodules embedded in Redwall Limestone (Mississippian) along highway 89a west of Jerome, Arizona. Also in this layer are crinoids, brachiopods and solitary rugose corals. I think I've read about these in the dim, dusty past, and I seem to recall that they are not fossils, but some other geological phenomenon. Any help?
  19. These tiny fossils I suspect of being Receptaculites, but I'm not at all sure. The patch is about 12x12mm, about the size of a dime. It's on Martin formation dolomite from the Devonian, Verde Valley, Arizona. Other fossils on the same rock include Rugose and Tabulate corals and unidentified Brachiopods. Note the lichens growing in and on the sample. Any ideas?
  20. Ok, I proved it possible to make polished slabs of substantial size (ca. 50 cm2) without any machine, purely by hand, in an acceptable time and of good quality and with things I already had, especially flat plates. Grinding and polishing media had to be bought, of course. All of this can be done on a desk in an apartment, no serious noise or dust production involved, just some sludge . Only one problem remains - you need an as flat as possible surface to start with. Such flat surfaces are usually produced with rock saws. For rock cutting, I have only experience with profession
  21. Hello, I found this piece on a beach in west Kerry Ireland. It is on what I believe to be a piece of limestone and I am wondering if it is an actual fossil or just a crystalline structure in the rock and if it’s a fossil which one would it be? Thank You
  22. I went camping over in West Texas in Kickapoo Caverns state park this past weekend. While I was hiking around I noticed dozens of these formation that were jutting out of the limestone boulders and bedrock. Not sure what they are but they seem to be shaped like small trees or medium thick branches. Anyone know what they are?
  23. Hey everyone, I found a ton of fossils littered on the ground around a cave entrance about a week ago. I took a few rocks home but can't quite figure out what they are. I've tried my best to light up the fossils for the pictures, but all the details were difficult to see when the photo was fully lit. A 10x hand lens was used to take the close ups. Ruler is metric. Geology: Bungonia Formation limestone, 427.4 - 410.8 million years old. Found in NSW, Australia ROCK 1 I have 2 rocks with the same fossil. I want to say it's a type of solitary rugose coral, but still not sure.. I s
