  1. 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...
  2. Hi guys! I am not sure if anyone has encountered such fossils before but when collecting fossils at the Salons Formation in PA this summer I found this brachiopod: This brachiopod is nicely inflated and has great detail, one problem is that the surface of it is covered in this layer of limestone with patches of calcite. I would love to get rid of it but I am really not sure how to go about doing so. Here is an extra picture of how it looks up close: Any help would be appreciated, Thank you!
  3. Wormish

    Found along the Missouri river...in S.E. South Dakota...any ideas??
  4. Hello all, I'm 19 and brand new to the site, I'm hoping this is where I can get a potential ID on some very interesting fossils a family friend of ours supposedly found 10 minutes east of Austin on their private property. The first of which is a mostly complete fossilized fish - according to this friend of ours, it was found close to a river, where limestone slabs stick out from the eroded bank. As far as I understand, this was from an old bank line rather than the current one. He pulled on of the slabs out from said bank, and on it (after appropriate cleaning), a fish skeleton was found as shown below: An ID to the genus at least would be very appreciated. Secondly, and perhaps more interesting, is a fossilized piece of skin (potentially) I know fewer details about this particular find, but he does say that he found it on the same property. Some other fossil finds he has made (he's not a vigorous hobbyist, he doesn't actively search for these, just passively and on occasion for fun) include some bivalves and the other typical gastropods of the area. Of the photos, he included a picture of a large vertebrae, which I believe may be a mosasaur vert - a find sometimes made in central texas. Anyway, the skin he found is below: I don't have much context for size, my guess is that it's probably about 2 inches (5 cm) in length. Thanks for any ID guesses! I hope I uploaded this in the correct area!
  5. Castle Hayne fm Mystery Fossil

    I found this mystery fossil at the Castle Hayne Quarry near Wilmington, North Carolina over 15 years ago. It was in limestone of the Eocene age Castle Hayne Fm. It consists of parallel shallow indentations that have grayish looking coatings in the bottom of them. I have had suggestions that it was a plant impression, soft coral, and bryozoan. I don't know what fossil forum to have it identified when nobody is sure if it's plant or animal. Any suggestions? The long direction of the specimen is about 3 inches by two or two and a half inches. 7.5 cm by 6 cm
  6. I have found a couple of trilobites on a friend's property near Eganville, but I don't know what the attached fossils are. I am pretty sure the last one is a number of shells, but any ideas on the other ones? Thanks,
  7. Wren's next - silurian Wenlock

    I've been cleaning away at this by hand, I can't get much further as the rest of the matrix is very hard. What have I been uncovering here? I thought brachiopod shell when I just saw the edge, now I have no idea. Looking at other pics of Wenlock fossil I couldn't spot anything similar. Can anyone enlighten me?
  8. Trip Planning- Le Grand Quarry

    Planning a serious Iowa excursion for my Uni before winter hits. Was curious if any of you have done any rockhounding around the Le Grand area. Apparently is a site for exquisite crinoid plates. Just curious before I start calling the stone company and procure access/permits/etc. https://www.legrand.lib.ia.us/Library-information/fossils/crinoidfossils was sent a link to this by a contact at UNL...hence my sudden interest https://www.iihr.uiowa.edu/igs/publications/uploads/Em-04.pdf
  9. Only a couple of one hour forays so far, I've only just had treatment on my hip so taking it carefully (by which I mean I'm clambering over scree slopes with little care but getting told off for it) Thought I'd drawn a blank on the trilobite front until I started cleaning this - and then I saw my very first trilobite! How small do they come?
  10. I found this fossil back in 2014 at Cedar Creek Reservoir in Franklin County, Alabama. I was told the fossils we'd find there would be Mississippian, contained in Bangor Limestone. When I first found this I thought it might be a trilobite butt or a shark tooth and I recently decided to try to clean it, and now I don't know what it is there are two depressions under each prong, and the prongs bow back up (couldn't really get a side pic) The pictures show the uncovered fossil (the lighter material was what was initially uncovered). Thank you for any assistance! On a separate note: I also feel terrible that I ended up damaging it a little (chipped the left edge on the bottom most segment)
  11. Reptile skin? Coral? Calcite?

    I thought this was my typical fenestellan bryozoan fossil when I first started photographing this rock, but when I looked at the photograph I realized that the texture was more bumpy and different... Other areas of this rock have what look like quartzite like areas - could this be something like that? My first impression was that it looked like reptile skin, but then I thought more rationally and highly doubted it. ;-) Found in Madison County, Alabama. Ramona
  12. I was recently reorganizing my fossil collection and thought I would share some pieces I collected during Paleontology field trips in undergrad at Alabama. I'm glad I took thorough notes at the time! The demopolis chalk is a popular formation for finding Exogyra/ostrea/pycnodonte shells and shark teeth. We visited a site in Tupelo, MS many times for surface collecting. Some of the cool pieces I found were many fragments of a mosasaur jaw (top pic, top 2 slots), a Squalicorax kaupi tooth, a scyliorhinus(?) tooth, bony fish vertebrae, and bony fish teeth. I was told the dark fossils at the right of the third picture might be ray plates, but I'm not sure. Turritella in pic 1 are from a different formation.
  13. strange little curved rock

    I think the curved part of this rock is probably just a coincidence, but since I have never seen anything like it before, I thought I would check. Like a lot of other rocks I find, it seems to have a layer of limestone fenestellan bryozoan fossils encrusted around it (that's about the only way I know to describe it) and lots of tiny impression fossils on the inside of the rock. Can anyone help me figure out the rock's story? What might have caused the curved and layered appearance? Is that just a coincidence? Or is this a particular "thing"? Found in Madison County, Alabama. I will post more photos in follow up comments. Thanks! Ramona
  14. I am learning to pick apart the items I find in the limestone fossiliferous rocks from my yard, but I see some things here that I am not familiar with. What is the tubular item at the bottom of the photo? And what are the tiny round black things? They look like poop, LOL! One of them is inside of a crinoid fossil, but it may have fallen there? This was found in Madison County, Alabama. I find fossiliferous limestone mostly with fenestellan bryzoan fossils, crinoids, coral, etc. Thanks! Ramona
  15. What is the best way to remove a fossil from Limestone? Thanks Greg
  16. Hi everyone, I found this fossil in Eastern Ontario. I was wondering if anyone can identify the fossil. I don't think it's a trilobite. I'm also wondering if it can be extracted. I believe it's in limestone. Thanks!
  17. Found this small oddity while breaking apart limestone. The pitted appearance was interesting. The pits also seem to extend the whole way through. They also appear to wrap at a 90 degree angle on the side that isn't broken. The broken side reveals how they go through. I chipped away a little at the matrix, but didn't go too tough to keep from breaking it. Whole specimen with scale: (stacked photo) Showing outside 90 degree wrapped edge with same appearance: (stacked photo) Broken edge showing channels going through the width. Additional view of the top (unstacked photo)
  18. Weird limestone fossil

    Does anybody know What this is? Found on a beach in Sweden but came from Denmark with the glaciers. I posted something before but a guy said the picture was not there so tell me if u cant see it and if so please then tell how to post im new here
  19. Die Grinders or Dremel?

    Hello all, I've done a bit of light prepping, but not much grinding. My typical matrix is a cement like limestone matrix that is hard to get things out of. You just sort of have to hope things come out clean. I bought an air scribe and use it often. It's not easy work, but eventually things can come out pretty clean. I have a couple of pin vices, but they are almost of no use with this matrix, there is so much calcite. I use them more often for shale. I use a battery and wired Dewalt grinder with a cement/granite cutting wheel to remove specimens from larger rocks. I have been looking into the battery or wired Dewalt 1 1/2in die grinder, but not sure if it would be as useful compared to something like a Dremel. I figure I would need some sort of carbide or diamond bit set. I'm looking to remove larger pieces of matrix before getting closer with the air scribe. Thank you for any help.
  20. Found these formations on the limestone of the southernmost shores of Alonissos, Greece (below the aptly named camping Rocks). I took some shots of the formations and collected pebbles from a nearby cove bearing the same characteristics. Any suggestions regarding their origin would be much appreciated, especially since there is little documentation on the island geology (according to the only geological map I could find these are neogene formations, yet there are certain geologists who, after visiting the island, suggest this could be a generalisation).
  21. Weird Fossil ( Missouri )

    Location is in Missouri The area is dated to the Pennsylvanian Formation: Probably apart of the Raytown limestone member Found this weird fossil on my latest fossil hunting trip, I personally believe it to be some sort of Amminoid since the pattern seems to extend away from the shell and not towards it, but I have only found Nautiloids in the area ( Only 2 spiral shaped specimens that do not look like this and 3 cone shaped.) If anyone can Identify if this is a an Ammonoid or something else I would love to know more! the middle Section with the weird ball like pattern in the middle and what I assume are gas chambers around it
  22. Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Formation I have collected a lot of concretions and here are a few of which I have no idea what they could be My possible hunch is that some of these could be Fossilized Cartilage? Was really interested in knowing what this one was
  23. Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Formation I usually collect a few limestone concretions from a rock pile I go to and a few pieces of what appears to be bone popped out! Unfortunately when it did crack some of the pieces went flying and were unrecoverable While I do not know if it can be identified, I can hope it can somewhat be recognized. In the area I have found fossilized Cartilage through my Concretion cracking adventures and have found teeth from specimen of Eugeneodontida in the area. I also have come across the usual Brachiopods, Crinoid stems, Bryozoans, Rugose corals and petrified wood in the area. I believe this is some sort of fish bone, as to what it was? I have no clue. Below is the left side of the concretion
  24. Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Formation At this pile I hunt at there are many concretions, but none exude the blue coloring as they are mostly black and much smaller. I am not 100% sure these are fossils but these are the only weirdly hued fossils I have found there. I have found a few teeth from Eugeneodontida, Horn corals, Crinoids, Brachiopods, Nautiloids and petrified wood from the area. I do not have any measuring tools that are not wood when I took these pictures. I apologize and hope this could be a decent size reference.
  25. Location Missouri Found in limestone that was blasted out by construction workers The area is Pennsylvanian on the geological map I have also found prehistoric fish teeth in the area along with Brachiopods, Crinoids, nautiloids and horn corals. I was not a 100% if this was a fossil or just a natural formation in limestone. I only say it could be a Pennsylvanian shark crusher plate but I am not 100% sure Sorry for not having a good size reference, I have very little measuring tools, and did not bring it to the site I found it in, there will be a ruler measurement of the hammer below I was not sure if it was biological in origin but the ridge makes me question, and those could be possible pores at the bottom? In all honesty I do not want to make assumptions XD
