  1. I noticed this interesting shape in the walkway to a corporate building in Germany. The walkway is composed of rectangularly-cut limestone(?) slabs. The size is roughly 6in x 12in. Any thoughts? I'm not even sure its a fossil, but the shapes strike me as organic.
  2. One of my first exciting finds was a piece that looked like a tooth back in March. Turned out to likely be just a cool shaped rock. Fast forward 3 months and I finally found this today, which I believe is an actual tooth. But I'm no expert, is my identification correct?
  3. Old Bone or Ancient Tool fossil?

    I found this piece of limestone that seems to be too much of a coincidence for it to fit in my hand just right. It almost reminds me of the manubrium of the sternum but then I thought it could maybe be an ancient carved tool. It could also be just a rock :-). Any help would be appreciated.
  4. Hi everyone! After the recommendations of @Manticocerasman, @gigantoraptor & @Joeri_R I joined the BVP (Belgian Association for Paleontology). Today I got my confirmation mail of the membership. I have long been wanting to go out on fossil hunts especially in my own region which consist of cretaceous limestone from the Maastrichtian. Luckily for me the next fossil excursion planned by the BVP is a trip to the Romontbos quarry in Eben-Emael which is only a 20 - 25 minute drive for me. So I did sign up for said excursion but since it's my first ever fossil hunt I want to go prepared and I was wondering if any of you have any tips on what tools and stuff to take with me to the quarry and what tools are best for excavating said limestone. I already know that a safety helmet, safety gloves and a fluorescent jacket are required and that safety glasses and steeltipped working shoes are recommended. I was also planning on taking enough water to stay hydrated, a backpack and a good strong bag to transport excavated fossils and perhaps some matrix to examine later. And I was planning on purchasing this kit from my regular fossil shop. Are there any other tools or items that I should bring? Or does anyone have some tips for an inexperienced beginner? Or is anyone is familiar with the location feel free to share. Thank you in advance and I look forward to my first hunt!
  5. Carboniferous Gastropod

    Found this piece in the same piece of limestone that my last questionable piece was in. It's a Gastropod for sure. It was split within two separate planes of rock. There wasn't any detail within the split, so I just glued the two pieces back together. I've found lots of gastropods in limestone, but they are usually really tiny. This one was a full size for once. Glued back together using Paraloid B-72. As close as I can say, this limestone is approximately 305 million years old. I've considered both Donaldina and Meekospira. Last Questionable Piece:
  6. Big clam?

    This thing is big, much bigger than clams and brachiopods I usually find. I haven’t attempted to remove it yet, because things this size usually break up when chipped out. I see shell material and some ridges in the steinkern. Excuse my clean hammer.
  7. I am nearly sure the top piece is Metacoceras. The middle is a clam, but what species? Perhaps Astartella concentrica? The bottom, what is that thing? 6477/6478 show it in detail. I find these a lot. Are they brachiopods? Not shown, but there is a horn coral on the back of the piece in a cross section.
  8. Wilkingia Sp.?

    Not my best photos, but a quick dimensional Wilkingia that I found over the weekend. Identification is likely but not solid.
  9. Fenestella? Bryozoa of some type?

    Tonight I found a new limestone ledge sitting 6 inches from a stream water level. My father and I started hammering away at the shallow edges and removed a ton of interesting specimens. While there were some nice cephalopods, lots of brachiopods and clams, this piece caught my eye. I’ve read about Bryozoa and I’ve seen similar things on fossil plates. I believe I remember seeing pieces of them in limestone while digging, but never anything big. So, is it a Fenestella? Or something else? I’ve never found one worth showing. I saw a species list for it and it is very long.
  10. A few Pseudorthoceras

    Pseudorthoceras is a bit of a mystery locally for me still. They are probably the most common straight shelled cephalopod I find. I also found at least one Mooreoceras. From what I understand, Mooreoceras and Pseudorthoceras are both classified under the Pseudorthoceratidae Family
  11. Hello, I almost die, when I was extracting this ammonite from wall of abandoned limestone quarry. So, that's my very first stone preparation, of 200 mm (7,8") ammonite (Perisphinctes), which I found near my hometown - Kraków, Poland. OK, I know, it's not so big, but the largest I have ever found. As You can see I got carried away, so it's half natural specimen, and half carving. Preparation I done with Dremel Engraver and some chisels I made from old files. I enjoyed it well
  12. Mooreoceras sp.? or something else?

    I’ve been air scribing this piece out and I figured it was a Mooreoceras. However, the ridge going up the front is something I haven’t seen on this species. Is it just squashed a bit? It’s a pointed oval in shape. The length is nearly 3 inches.
  13. Help with possible fossil

    I found this today while walking the shoreline of the, St Croix River in Stillwater, MN. Is this anything?
  14. G'day everyone! I have become increasingly interested in finding conodont fossils and have found a locality near where I live that is rich in paleozoic vertebrate micro fossils, including conodont teeth. The locality is apart of the Coopers Creek Limestone formation, early Devonian in age and rich in carbonate. I have checked out this locality before and the rock is very, very hard (It has no layering and takes a few hard hits from a hammer to smash the rocks open). My question is what is the best way to dissolve these rocks and once dissolved what should I do next to find the micro fossils? I have read some where that hard rocks are soaked in kerosene for 24 hours to break them down but I don't really think it would be safe to use kerosoene and also expensive to buy enough kerosene to soak the rocks. Here is a link to a paper on the site: http://paleoitalia.org/media/u/archives/28___Basden_1999_BSPI_37_527-541.pdf Thanks, Dan
  15. Brachiopod, but which one?

    By far the most detailed Brachiopod I’ve found to date. The top impression, which isn’t shown, appeared to have two larger bands running down the center. The small piece in attachment 3 was somewhat of a steinkern or impression below it. Scale line is 1cm. Photos taken with a DSL through a microscope. This came from eroded Limestone.
  16. Brachiopod?

    This one showed up after a rock split. The steinkern was really shiny and smooth. Usually the shell is hard to save, but I was able to when air chiseling away at this one. There are noticeable grooves on one side.
  17. Hi everyone, Once upon a time, I was a young college student at UF whose favorite hobby was spending hours trudging through swamps and up and down creekbeds in search of gravel beds and limestone banks. There were no other types of stone worth noting, so every stone was either limestone or imported. Fossils might not always have been easy to find, but when you did find them they generally were sturdy things that were practically falling out soft limestone or clay. My tools were a hand spade and a homemade screen in a wooden frame, that's it. Fast forward a decade (or two...) and I'm trying to get my kids into the hunt from our new home in the Pacific NW. But things are so different here. The rocks are all strong! So many of the fossils seem so relatively weak! I heard about the Lincoln Creek concretions and that sounded like fun until I saw what you guys go through to prepare those things ... I'd need a whole new workshop just dedicated to that! As I read about all these fossil-bearing formations in the Cascades and Olympic peninsula, most of them sound similar in terms of the difficulty and gear required. So... I'm probably going to take the older kid at least to collect concretions in the next few weeks, but we'll have no plans for what comes next. Actually, I'm pretty sure it will end up with him smashing them "carefully" (with proper eye and dust protection, of course).
  18. Advice on Prepping Limestone

    Hello everyone, I'm New to the fossil forum. I'm from Minnesota and I've got some nice sized Ordovician fossil from the Platteville formation in Rochester, Minnesota. They're in Limestone sediment. One is a slab that is a filled on both side with crinoid stems (hoping for other rarer parts under the sediment on this slab). The other two are large section on cephalopods. I'm looking for some advice/tips on how I should go about prepping them. Like what kind of tools should I be using and if I should use any chemicals. Any advice/tips would be appreciated. Still fairly new to fossil preparation. Also if better pics are needed I can get them Thank you
  19. Kansas Fossil - Saline River

    Found these around Saline River in Kansas. Black with striations and crystals. Found in or near limestone.
  20. My dad actually found this a few years ago in our driveway and thought I'd know what it was so he brought it to me. Pretty sure our limestone gravel came from an Indiana quarry. Haven't really been able to figure out what it is. Some of the grooving looks like it could be a clam but the things that kinda resemble teeth are throwing me off a bit. Anyone think they could help me out?
  21. I collected with @ rwise in the Goodland Limestone, Lower Cretaceous of Cooke County Texas today. I found this semi-circular fossil that may be a burrow. Looking closer at the large end there was a dotted line, lower left. Closer... Closer... Closer... That's a mm scale and this is the best my camera will do close-in... Any ideas?
  22. Oolitic limestone

    Not a fossil (although in some contexts, a pseudofossil), but I cut and hand-polished a piece of oolitic limestone this evening. These are nice, big, ooids (pisoids in this case), and one can easily see the layering. I thought some might like to see the results (scale in mm).
  23. Crab carapace?

    Unknown fossil. Found just below a tidal deposit and above a deep water lime deposit. In this layer there are a lot of good sized amonites, and a smattering of pelecypods and scallops and oysters and protocardia and urchins that become much more common just up the rock sequence. Just a bit deeper are fairly common trace fossils of burrowing shells.
  24. Any ideas of what this is

    Anyone have any insight to whether this may be a fossilized claw of some sort or just a peculiar shaped piece of limestone. I found this in central Texas outside of Bandera. Thanks in advance for any help.
  25. Last fall the state of Illinois purchased over 2,600 acres near the town of Oglesby from Lone Star Industries, including former quarries, with the goal of making it into state park land. It is near the site of the popular Starved Rock and Matthiessen State Parks, and the state said it would take a few years to assess and prepare the site before it would be open to the public. http://www.newstrib.com/free/matthiessen-and-starved-rock-just-got-a-lot-bigger-video/article_203e37f8-d89a-11e8-9a7e-e72ef52ec0d6.html The quarry exposes the highly fossiliferous LaSalle Limestone, as well as a black shale that produces fossils too, so a number of scientists and fossil enthusiasts proposed that a portion of the new protected land should be made into a public fossil park- here is their proposal: https://www.esconi.org/files/proposal-for-a-fossil-park-at-the-former-lone-star-quarry-site-final.pdf Now a state legislator representing the area has introduced a bill to do just that- the synopsis reads: "Amends the Department of Natural Resources (Conservation) Law of the Civil Administrative Code of Illinois. Provides that the Department of Natural Resources shall designate a portion of the former Lone Star Quarry site near Oglesby as a fossil park to allow for the collection of fossils. Provides that Department by rule may designate which portion of the land shall constitute the fossil park and any requirements for admittance or permits for entry into the fossil park. Provides that the Department may collaborate with any State university to establish educational opportunities or events at the fossil park." Hopefully this will become a law and this park can join the famous Mazonia-Braidwood as Illinois's second park for fossil collecting. If you are an Illinois resident, please contact your state representative and tell them to sign on as co-sponsor or support this bill!
