  1. The following set of photographs is of a roughly 5-inch x 5-inch x 7-inch limestone fossil. I found it in Eastern Anatolia along the Turkish-Iranian border near the village of Uzengili. It exhibits striations from what I call "top" to "bottom", although there are some (only 2 or 3) horizontal striations that seem to have a replacement material akin to quartz, in that it appears clear (but very thin). At first I thought this was a coral, but I am beginning to wonder if it is a Stromatoporoid Sponge... however, it could be something entirely different, and that I why I am presenting photos of it in this forum to see if anyone recognizes this morphology. The following photographs show the fossil in rotations of 90 degrees (which I have labelled North, East, South, and West for reference). I also have a "top" and a "bottom" view, although what I label as the "top" may actually be the "bottom" if it turns out to be a sponge and not a coral. Of note are some tiny features along the "bottom". These features may be part of the fossil, ore perhaps they are growths of some other material that has leached out of the soil and onto the fossil. These features seems quite well integrated with the rest of the limestone. What is curious is the fact that the "bottom" looks like it is a fracture, in that it is smooth with few features other than some parallel striations. To have these intricate features survive on a fracture plane seems odd to me and that I why I am suggesting that they may be leached material. I am an engineer and not a geologist or paleontologist, so some expert identification help would be appreciated.
  2. found this relief in the limestone at bluffers park it is just over a foot long any ideas what used to be there? there are lots of fossils in the limestone boulders used for the breakwall found some calcite vugs too i will post more pictures here
  3. Hi! i found this fossil, among with many others which were Crinoidea in limestone. This was lying amongst the limestone pebbles which contained minute fossils. This one caught my eye, at first it looked like a rock but on further inspection it got me thinking it could be some sort of fossil. It has lines running along it, in one direction, they taper down to the bottom which I also have took a picture of. It was found on the coast, and the site I went to is renowned for its many crinoid and coral fossils. The whole shoreline was mainly limestone. I was thinking it was some sort of coral or shell. It measures approximately 5cm in length. Maybe a belemnite? Thank you!
  4. Hello, Long time occasional lurker, first time poster; I hope this is the appropriate place and method for posing this question, and I apologize if it is not! I have some limestone blocks containing conodont teeth and shark teeth, which I would like to break down with acetic acid. From what I have read, adding a buffer to the acid solution would greatly help in preventing damage to the teeth (and especially the roots), but I have no idea what buffers are readily available (and from where they would be available) and commonly used (and how much is needed). Can anyone advise? Any experience you've had with buffering acetic acid for dissolving limestone matrix to retrieve small teeth that you'd be willing to share would be greatly appreciated! Much thanks! :-)
  5. So I took a small rock from Vojak peak of Ucka (Uchka) mountain in Croatia. Later I noticed interesting (well, it's interesting to me, since I know close to nothing about fossils) shape on it. I wonder is it a fossil at all and if it is, what was it fossilized there? The rock is limestone: I would appreciate your help in identifying it.
  6. We recently found this sample at about 300 meters elevation, 20 kilometers from the ocean. Can anyone give me an idea of their age from these pictures?
  7. A few things in this rock.. any ideas? Thanks
  8. The tags about cover it. García-Garcíaplapueyquaterntufatravert2013.pdf
  9. And some geochemistry as well.. A reasonably instructive figure 10(carbonate dilution,cyclicity) reboupittetpalcu3de.pdf
  10. This was found in Pahrump Nevada. Can anyone tell me what it is? Please?
  11. I have to write this because I'm hoping someone can help guide me on where to even start. I have looked over the pinned posts on the top of this forum but I feel like my question is a little different. In all my gardening and digging I have started to find too many (whati believe may be) fossils. I've also realized that a lot of the limestone we have collected from the ground here actually might contain fossils. To be clear I am not actually expecting someone to ID all of these photos, I just want to know where to even start?? I am not a paleontologist nor was I even interested in it until I started finding all of these. I am a work from home mom with a toddler and I really don't have time to learn everything there is to know! I can handle the smaller things like the shells and barnicles, but these giant rocks have me overwhelmed. Someone come help me! I don't even know what some of these rocks are... some of them were covered with the blue clay... these rocks were about a foot underground.. Location is Sarasota, FL. I'm going to put a couple of links to some of the photos because there are too many to post. Any guidance is appreciated! The photo included is to show you just some of the pieces lined up ... some close up pictures are in the links. *edited to say that I am not able to bring these anywhere because they are huge. Also, I have tried contacting a few people at local universities but without luck. I have become sort of obsessed with even just the little fossils and my worklife has begun to suffer... I feel like I need to do something with these...if there is nothing of note here I want to just be able to know... these photos don't even begin to cover the shells. If anyone lives nearby and wants to come help!! Please. Sorry if there are duplicate photos I was just trying to do this quickly
  12. Hello from Finland! Please help me identify this small (3 cm) limestone fossil from the sea shore. Best regards, Kara
  13. For some strange reason the term 'small flake of bone' sticks in my mind as the likely evidence to be found of early fish. It came to mind when I noticed this shape under the loupe. My dating of Ordovician is based on the fact that I find the cross sectional shapes of Prismostylus in other of the distinctive rocks. I'm fairly sure they are actually crumbs that rolled of onto the lake shore during construction of a rail bed. It's so small I had a hard time getting a clear shot of it, but do you think there is a chance ?
  14. Hi all! My 6 year old son found this in a river bed in Austin, TX. We have a lot of limestone from the Cretaceous. He is so proud of his find! But we don't know what it is. Could anyone help us identify it?? He would be so thrilled. Thank you!
  15. Hi Guys, Found this chunk of limestone containing some interesting features (pics 1-7 of 8)while walking a beach today in the west of Ireland, there seemed to be a few more rocks similar to it scattered around the area. I have very little knowledge of fossils and would really appreciate if someone could help me identify the fossils present. The image 8 is a separate fossil picked up in a drumlin, I was thinking that it looks a bit like some sort of shell, but again would appreciate an id if possible. Thanks, H
  16. Hi guys, I'm new to the forum .I found three okinawan fossils in limestone.Can anyone help me Id them?
  17. Hello all, I'm working on a project for my Geo 200 class and I am having some trouble identifying the fossils on a rock I was given (pictured with the white bar representing 2 cm). I believe it's Bryozoan but if you have a better explanation please share. Thanks!
  18. Wrens Nest slab

    From the album Multi-slabs

    Don't know what this is yet. Slab from Wrens Nest, Dudley, The Midlands, U.K. Silurian Wenlock limestone formation.
  19. Hi esteemed forum members, I have several finds I need help identifying, but I'm going to do them in separate posts/threads/topics/whatever. I found this one in some Burlington Limestone in central Missouri. It's super brittle. You can see areas where pieces have just flaked off. The lines you see going across the front of it are raised. The leading theory on this so far is that it's a Rhodocrinites calyx that flattened during diagenesis. I've also attached an image of the small matrix it came off of (I found the calyx, if that's what it is, in situ unattached, just laying there on top of the matrix). Let me know. And stay tuned for other, and probably less exciting, ID requests. Thanks!
  20. I found this fossil in Southern Germany on a mountain range called the Schwaebische Alb. It was found in a former marine envornmnet with bivalves, belemnites, etc It is relatively large, the rock is limestone, and I do not know what it is. Does anybody know? (I attached both pictures)
  21. I walked some old abandoned rail tracks today after work, near Lake Michigan. Now I'm assuming they trucked in local limestone to use for these tracks, which would be Silurian. But I also have learned assumptions have no room in science. Haha! That being said, I can't confirm a time period for these finds. Limestone is a tricky thing when it comes to fossils. Sometimes it preserves the finest of details, and sometimes it's a worn blob. I found some cool stuff. Nothing great. But it was a very relaxing and easy hunt! And sometimes those are the best kinds of hunts! Corals Cephalopods Mystery item #1. I'm thinking an impression from the side of a Crinoid Cup. What do you guys see? Mystery item #2. I'm also thinking Crinoid Cup, but an impression of the bottom. Thoughts? Mystery item #3. This I haven't a clue. At first I thought some strange Brachiopod, but it's so round. Hopefully the pictures convey it's strange shape and characteristics. As always, I appreciate any and all help. Thanks for looking.
  22. Hi all, Here is goes, finally I found a place "alive" enough to talk about fossils. Most other places I saw were just as alive as the fossils they were supposed to talk about. Sohere I went on a trip onto an island in Lake Winnipeg in Manitoba, Canada. The ground is shale or limestone. Just walking on the "beach" I came across a bunch of fossils or imprints of fossils. Now I tried to find out how old that particular spot was and came up with Ordovician. Here are the images of what I saw: 1: 2: This one looks like a fish, but I doubt is a fish would leave such a lasting imprint 3: This one has my size 12 shoe in it for measure, but I saw the same type of imprint that was at least 5 to 6 feet long. 4: Can anyone point me in the right direction or even identify these fossils for me? Thanks, Henk
  23. I recently moved to Ocala, Florida and I've been enjoying fossil hunting right in my neighborhood. I've learned a lot by reading these forums, and studying up on Florida's geologic history. This one has me stumped. There are well- defined layers and concentric circles at two corner of this rock. Any ideas ? Some parts of it are brittle, crumbly limestone. But some parts are quite hard and seem to have chert inclusions. ( I've seen a bunch of that around here. Beautiful ! )
