  1. Hi everyone, first time poster. I found this rock at Blue Beach, Nova Scotia near the water line. At first I thought it was an organic specimen, like perhaps seaweed or roots growing on a rock, but on closer inspection it appears to be mineral. Ive never seen anything like this before. It looks a lot like petrified roots, but I figure thats unlikely. Does anyone know what this is? The last picture is from a magnifying app.
  2. Found these nice fossils not on a planned hunting trip, but while working in the garden. We were filling up some flower pods whith gravel, in which i found them : 6 belemnites, 2 pieces of mineralized wood, 1 partial oyster shell, and 2 pieces of baltic jade. The highlights are definetly the pieces of wood because theyre quite rare up here and i have never found one before. Also one of them is beautifully preserved.
  3. My family and I went on a trip to Yellowstone, the Green River Formation and the Blue Forest in Wyoming. Although my son found by far the best Blue Forest specimen, I thought smaller specimens were also of interest. The attached image illustrates a common theme of the petrified wood specimens. Typically, the outer bark results in a fluffy white deposit of calcium carbonate. The inner bark is often composed of what the locals refer to as "blue opal" (likely chalcedony), and then the center part appears to be silicified wood. Some specimens had iron oxides as well. I highly recommend a trip to the Blue Forest. It is very out of the way and directions are hard to find. The directions we found at one point stated that we should turn left at the gravel road with a rusty barrel at the intersection. We traveled down the gravel road for many miles until we spotted dig sites. It is very remote and you would want to make sure you vehicle is in good condition with plenty of gas and that you have plenty of water.

    Conus

    From the album: Miocene fossils from Qatar

    A calcite replaced miocene conus fossil I found. The rock itself was collected early last year but I cracked it open to look for echinoids. The calcite is paper thin and very fragile, and the inside of it is also filled with numerous crystals. Dam formation Abu samra member

    Crystals covered coral fossil?

    Hi guys , I hope you can help me in identifying this rock .I found it in a small dry river in Catalunya. It is covered by small quartz or calcite crystals I think. I am not sure if it is a fossil, maybe a coral fossil? Thank you 🙏
  6. Hello again everyone! After a quick trip out to Holden Beach with some minimal finds, I was left with some indecisiveness on the location my next fossil hunt, I was presented with the opportunity to go back to Surry County, Virginia to hunt the same locality as I did back in August. I was a bit unsure if I wanted to make the trip again, as I had a fairly rough time during the last trip with some stomach issues, and I had felt I had a decent enough haul from that time. However, after Tropical Storm Ophelia went through the area dumping a lot of rain and the forecast was predicted to be much cooler than August, I decided to make the return. I can say with certainty I am very, very glad I made this trip! I was also given the opportunity to stay on site this time as well, which was really cool, and I made a few new friends with the fellow hunters that were also staying there. This is once again very picture heavy so hang in there once again. A small note, I had previously though all of the fossils were from the Yorktown Formation, but I was corrected on this; the site is primarily Late Miocene Eastover formation, with a fair bit of Early Pliocene Yorktown Formation, with the cobbles from the Cambrian Swift Run Formation mixed in in places. Starting again with some pictures of the site, not much had changed in two months, aside from some of the cliffs collapsing partially, which unveiled some new, fragile bivalves. The sand they had put on the beach that covered some of the material had been washed out a little bit, so there were more fossils and Cambrian cobbles at the water line than previously. It was particularly rainy on Saturday morning, but as the day went on it warmed up to a comfortable temperature, and became sunny. It was very breezy this time around, so the waves were particularly rough the whole weekend, which helped expose more fossils on the beach. There was once again plenty of cool wildlife in the area as well! This unfortunate fellow was struck by a propeller and washed onto the shoreline late Saturday night. The damage was mostly on the side lying in the sand. This was the first time I've ever seen a sturgeon outside of an aquarium setting. I reported it to a researcher at VCU, who collected it the next morning. He told me it was a male, estimated to be 30 years old. It was around 1.676 meters (5.5 feet) long. I was able to hunt one particular spot in the area where the exposure was fairly close to ground level as well, here is one small look at that exposure. And as a brief glimpse into my finds, here was one such find in situ! (Courtesy of one of my fellow hunter friends I met during the trip) I don't have a particular order to show off this time around, but I'll start with my absolute favorite of my finds this trip: Ecphora! I was a little bummed out last trip that I was unable to locate one, but I lucked out big time this trip. The quality of them is all over the place, but I found a few that were especially good, including the one I had pictured in situ. The one in matrix was found accidentally when I was doing UV light hunting (Which I'll talk about in a bit). This was my favorite one! It's around 11.43 cm (4.5 inches) long, and 8.89 cm (3.5 inches) wide. A very small bit of the outer edge of the opening did break off while I was handling it after this picture was took, but fortunately I had some strong adhesive handy and was able to get most of it secured back in place. On to the UV light hunting, I spent a few hours after dark hunting for calcite and calcite-converted mollusks. I found quite a number of calcite clams, as well as some pretty good crystals as well. Two clams in particular had some fairly decent calcite crystals growing inside fractures between the two valves, which was really cool! These are two small clusters growing on some material. These were particularly luminous with the UV light, much like the crystal-covered clams. Here is a calcite-replaced Turritella on the right, and on the left is an odd-shaped chunk of calcite. It almost looks like the shape of an Ecphora shell's lower half, which makes me wonder if it could be a calcite cast of an Ecphora interior. Here are a few large coral chunks right after I has washed them off. (Septastrea marylandica?) A couple of scaphopod "tusk shells" (Dentalium attenuatum) with a lustrous, double-valve Pandora clam. Some fairly intact Turritella shells. (Turritella subvariabilis?) I found quite a few nice double-valve Chesapecten this trip. Some show up in the UV light at night, which helped me find them. However, some of the larger specimens had a lot of erosion or biological damage to them such as bore holes, so they would fall apart when I tried to clean them. I still ended up with a decent number of them, so it all worked out in the end. The leftmost specimen has a bit of calcite on the outer edge. Here is my largest Chesapecten next to my smallest once again (the large one is about 17.78 cm, or 7 inches, wide). Some large clam tubes I found. (Kuphus fistula?) A few gastropods of decent quality with a double-valve oyster and a Crucibulum limpet. (Crucibulum grande?) This Naticidae shell (Lunatia sp.?) is fairly large, probably my favorite gastropod aside from the Ecphora! Unfortunately, it's extremely fragile, so I refuse to move it until I get something set up for coating my specimens. Because of this I haven't measured it properly. There is a smaller specimen in the opening underneath. A half whale vertebra alongside some different rib fragments I found. One of the friends I made found a fairly sizeable, nice quality whale vertebra. I found this nice tympanic bulla with only a small bit of damage. Definitely better than the one I found in Green's Mill Run! I found this micro crab claw dactyl while cleaning a different specimen. Some areas had microfossils inside of larger specimens, depending on how the preservation was. I finally found shark teeth as well! The white mako is around 5.715 cm (2.25 inches) long, and if the marbled one had it's full root it would be even longer. I found the bottom four purely by accident while getting the coordinates of the deceased sturgeon early that morning. One visitor found a half Otodus megalodon or Otodus chubutensis tooth with beautiful serrations. I found a lot of Discinisca lugubris brachiopod shells this time around, particularly in the area where the calcite was common. Here is one with some calcite to the left of it. There were a lot more Skolithos to be collected this time! The first specimen was given to me by the man who put the whole hunt together, and the second one was one I found later. These particular specimens are nice because they are visible both as cross sections and from above / below, whereas usually it's just one or the other. I found a new type of scallop this trip as well, Placopecten! These are also extremely fragile, so they're currently on-hold and sitting in one spot until I can get some better preservation for them. This one I'm a little unsure on, I'm thinking a Cliona sponge but it might also be a bryozoan colony. It's on a fragment of Chesapecten with a lot of sponge bore holes. (I'll make a post with better pictures in Fossil I.D. later when I get time.) The last on my major finds, these are some intact clams, and they are a lot more durable than the last ones I found! I can handle these to a higher degree than the other ones I found without them falling apart on me. I still want to get some kind of preservation on them. Someone at the hunt recommended Krylon clear coat, I'll have to experiment with it on some other specimens. And as a bonus, these are not my finds, but one of my cabin neighbor's finds. This is an regular echinoid he found, as well as a plate he found containing a fragmented Mellita sand dollar. While I found the very small fragment attached to a Chesapecten, according to the man who set up this hunt he's never seen a sand dollar like that found in the locality, making it a first. That's all for now! Nothing new on the Triassic spots, but I'm closing in on one, and the other is looking promising for next January once hunting season has passed.

    Fossil replaced by calcite?

    My preschooler found this on a hike in western pa. We scoured our Audobon and cannot figure out what it is a fossil of, if it is one at all. I am afraid to ruin it by cleaning it. UV reactive, fluoresces bright yellow-green. Thanks to all you brilliant folks for your help!

    The Creekend Warrior Collection

    Been at it for about a year now and I try to hit the creeks at least twice/month if I can help it. The "loose" pics are either newer finds that haven't made their way into the display yet, or finds that have their own display. Most of these were rescued from the Gainesville area. Some are from the Peace River & Joshua Creek, as well as Manasota, Caspersen, Venice & Fort Clinch beaches. I was also lucky enough to discover a previously unknown spot VERY close to home, while scouting one day! Dr. Hulbert (w/ UF) confirmed it is a new spot, but was reluctant to check it out as none of my initial finds were extinct species... I have since found horse teeth at that location and can't wait for water levels to go back down!!! Hoping to add a few new species to my collection on my upcoming trip to GMR & one of the Summerville creeks (not sure which one yet but would love to find my first Angi & GW)... the GW in my pics was actually found by my Grandfather in Panama in the 70s! Thanks for looking : )
  9. A calcite river, that is. Here are two burmite pieces that have a vein of calcite running through the arthropod inclusion. In this millipede sample, the calcite seems to have run along part of the dorsal edge of the animal, displacing it downwards. It is best seen in the images from within the millipede exoskeleton. The calcite flow was influenced by the tissue of the previously deposited inclusion. I thought it interesting that the process of cracking and calcite infiltration and solidification does minimal damage to the older tissue.
  10. Hello everyone. I offer interesting gastropods with calcite crystals - perhaps someone will be interested I have a lot of them. Pseudomorphoses of calcite after gastropod shells of the genus Nerinea from Upper Jurassic limestones of the Oxfordian stage (Izyum Formation J2-3iz); 163,5 mln years. Ukraine, Donetsk region. I'm interested in everything - I invite you to private messages Have a nice day VID_20220122_135535.mp4 VID_20220122_135732.mp4
  11. Looking for some info on this specimen from Eastern MO. Is this perhaps some sort of cephalopod impression partially replaced by calcite crystals? Thanks!

    Mystery Danville Trace Fossil

    Hi all. I found some pretty cool boulders of calcite littered with crinoid impressions in a public park in Danville, IL back in late August, but left everything until I got approval from their park department to remove them. I finally heard back last month, but didn't get around to going until today. I found a few interesting things that I'll post when they're cleaned up, but I probably won't even begin the process until Thursday. In the meantime I took a photo of a trace fossil that was sitting near the top of one of the specimens. I can identify most of the things in the pieces, but am stumped by this one. I probably should have gotten a ruler for measurement, but I snapped it after picking my son up at school and had to do it quickly. The photo didn't come out as clearly as I had hoped, and can retake it if necessary. It came from Vermillion County, which makes it Pennsylvanian. Any ideas?

    It's very pretty whatever it is..

    Picked from mix of QT, QAL, and Eagle Ford gravels. I love calcite but it can be deceiving, not sure if this was replacement of something or naturally formed structure, appears to be fossilized something. Curious about the red, mineral staining maybe? Last pic is view from above.

    Please identify this ammonite?

    I have no knowledge of this ammonite’s history. Does anyone have any idea of its type? It’s about 5 to 6 inches in diameter, a portion of it being fossilized with calcite.
  15. Went to creek I frequent but went down to a part I haven't been to for awhile, had several good floods since. Much to my surprise I rounded a corner and the bottom of the creek was pale yellow as far as I could see down. As you see in the picture there was shapes carved out by water, and it was very thick in places, but it was soft enough to break of pieces and it was grey underneath. So is this a layer of shale? If so why is it yellow? This may be natural in Eagle Ford and I've just never seen it in this form, just looking around I spotted this ammonite and just plucked it out. So now wondering if more fossils are deeper in this and how long it will take to erode down being so soft. One interesting calcite rock I picked up not far away, it's a jumble of pieces of fossils but the center has these fine layers of sheets with delicate veining I'm thinking is something that may be recognized.

    Calcite shell?

    Hello everyone! I haven't posted here in a long while, mostly due to lack of finds. I dug this out of my collection, and wondered what it could be. It looked like some form of calcite, but has an oddly organic shape. I also noticed that it has some small fossils, possibly shells, attached to the bottom. It came from Al Ain, United Arab Emirates, near the foot of Jebel Hafeet. I am not sure of the age, but I assume it is Miocene. I have found many numulites close to the location, as well as gastropod steinkerns, and urchins.
  17. It was late, my back against an old brick building. Light rain comin down. Felt a bit cold. Pulled up the coller on my trench coat. Wondering how long ive been standing here. I realize there is a glare on the street from the lamp post. I pull the brim of my hat down. Then I see her. I tell myself to stay calm,,,, keep cool. I take the last drag off my ciggerett and flip the butt onto the street. The orange glow snuffed out immediately. I study her from underneath my hat brim. I can tell she has been worked on before. I don't move. I keep studying her. I can tell that she needs work. Just need time. I know the sun will be up soon. Ive got her where I want her. She will be a real looker. Just need time.

  18. Found this in same creek by DFW airport, Eagle Ford/Alluvium mix. So has basic shape of an ammonite but really thrown off by strange pattern, not typical wear and each side so different. Just don't know what to make of it.
  19. Parkinsonia parkinsoni (ammonite) Jurassic, Upper inferior Oolite Bridport Dorset. UK 6.5" The first photos I took a few years ago did nothing for this unique specimen. I found it difficult capturing the details and still think they could be better. The ammonite has many chambers preserved in calcite that glow when backlit. Calcite crystals can be seen growing inside some of the empty chambers. Fossil, mineral, crystals, art, science, love Happy collecting.
  20. Hello, I found this interesting looking specimen in Port Charlotte, Fl. It is 2 inches (50.8 mm) long and 1.25 inches (31.75 mm) wide. It has teeny tiny honey colored calcite crystals in the segments and in the crack in the one end. I can see the crystals with a flashlight. I have many shrimp burrow casts but none of them are segmented, this is what it reminds me of though. Thanks for looking. Marie
  21. What is the best way to remove a fossil from Limestone? Thanks Greg
  22. I have some matrix pieces from ruck’s pit in Florida with some awesome calcite replacements And formations in the shells. I am open to all kinds of offers, including looking for other kinds of Matrix pieces, fossil fish and much more!
  23. Hello again, This is an interesting find found at the causeway in Tampa Bay, Florida last year. Looks like calcite covered coral or a sand fused fulgurite which I'd prefer to add to my collection, lol. What do you guys think? Thanks!

    Florida Fish Fossils

    Here are some of the fish fossils I have found, the first picture are some bones that I was hesitant to call fossils at first because they where scattered on top of a pile, but after find several other clay pockets ful of these I feel pretty good about them being gar fossils. Can anyone confirm, the internet is not being super helpful on this one? The next two are encased in a calcite geode i picked up while picking through the overburden, I didn't even see the imprints until i had washed it at home. Any ideas of what they are? From what i can barely tell, there are more in the geode, just not in convenient positions, and i don't want to break it to find them, a bird in the hand kinda deal.

    What type of calcite

    I found these in a large pile of dirt in a new housing development in Venice FL. I'm assuming they are calcite, but was wondering what type and what they are growing, incapacitated in. I found a lot of them and attaching 3 examples. They are holding yellow and growing on a charcoal, bulbuls rock. Thanks
