  1. Help with Mississippian crinoid calyx

    I took my 4 year old Son geode and fossil hunting near the Missouri, Iowa, Illinois borders last weekend. We had a blast and found a lot of cool stuff. I found this calyx in the Warsaw formation which is Mississippian. It's obviously not done being prepped, but i figured there might be enough showing to get your opinions. It's actually been quite a challenging prep and may take some time to finish. I was thinking a possible Agaricocrinus sp., but it doesn't quite fit the bill. I can't find anything that looks identical. Any help is appreciated. @crinus @Crinoid Queen you guys still around? As found Some prep
  2. Fossil id

    Hi. I found this fossil on the Lake Michigan shore in rocks that were brought in for a seawall, so I don't know where it might actually be from. Any help is appreciated. Thanks
  3. Limestone fossil

    I found this odd pattern on what Im guessing is a fossil...
  4. Kansas Petrified Wood?

    Found in Ellis county Kansas. Saw a small section sticking out and when I started to wash it I saw there was quite a few packed into the rock. I was able to get most of the rock off (I’m thinking limestone maybe?). Are these all little pieces of petrified wood? They are grey in color, the largest piece being about half an inch across. The black rock is intriguing as well. There are small black specs all over and then the larger one, seen in the first picture. There are also also a few shells smashed into it, but they are pretty difficult to see. I have a few pictures showing the entire thing and some close ups.
  5. Any ideas what this is

    Weathered out of the limestone cliffs at Torquay in Victoria. Not sure what it is ?? Does anyone have an idea ?
  6. Not sure if this is a fossil

    Found on a beach near limestone cliffs just wondering if it’s a fossil and if so of what ?
  7. what is it?

    i found this eroded out of the limestone bluffs, at first i thought crinoid but i dont see any form of symmetry or hole in the disk. is it something else? maybe a vertebrae? its about as big around as a dime and a few inches long
  8. Found this little guy about 2-2.5 inches in Northwest Kansas. I was thinking it was some kind of shell maybe on another shell, or perhaps a layred rock. When I found it, all that could be seen was a tip of the darker brown shell, the rest was completely covered in, I believe, limestone. Anyone know what I’m looking at exactly here? I have another piece much larger that looks very similar, but I am still working on cleaning and preparing it. Once it is finished I will also post pictures of that one. I can add more pictures as well.
  9. Marks in limestone rock

    What makes Mark's like these in limestone? There r three rows in this three inch limestone. Thanks for helping railguy
  10. Isotelus

    I found this last month on a visit to an abandoned limestone quarry near Naponee, Ontario. Though I am not very familiar with the Trilobites of this area, I believe it's an Isotelus. If I'm wrong with this identification, please tell me. It looks like there could be more of it underneath the sediment, and there is some matrix covering the pleura. This limestone is flaky and darker than any I have seen before. How would I go about prepping this? Though I've heard many people use sand, should I use something less abrasive, like baking soda? Thanks for the help.
  11. After my visit last week (http://www.thefossilforum.com/index.php?/topic/86063-my-little-trip-to-solnhofen/) This time I was at the visitor quarry in Solnhofen. It was very hard work and it was too hot but the finds arent too bad Its a pity that I couldnt find a fish but nevertheless I found some interesting things! Two pictures of the quarry: A beautiful 4 cm long Laevaptychus: A cuttlefish remain: with nice details (6 cm long): And my finds of the day: Two teeth Teeth arent that common in Solnhofen I assume, so I must had some serious luck The first one is 1.5 cm long and it seems to be a crocodile tooth. I think its a Steneosaurus tooth: I like the root The second isnt that big with a length of 0.7 cm. I cant determine this one... Maybe also a crocodile tooth? Maybe someone can help me a bit with determining? Thanks for your help! Hope you enjoyed the pictures!
  12. Please ID

    I wish I had a clue here! I am the nature and wildlife person people come to to identify live things. So now I need someone to help me ascertain if there are fossils in here. This is a soft, porous stone that was in a bed of ornamental river rocks, near the St. Lucie River, in Martin county, FL. When I grabbed it I thought it was an owl pellet. But it's a rock. Is that a jaw in there? and bones...? Thanks.
  13. My little trip to Solnhofen

    Last weekend I used my free time to visit two locations in the area of Solnhofen. Solnhofen is quite a famous fossil location, so many of you will probably know it. During the Late Jurassic, this area was an archipelago at the edge of the Tethys Sea and it preserves a rare assemblage of fossilized organisms. The most famous fossil from there is the Archaeopteryx. At the beginning I was very unsure if it really make sense to visit that location, because I often heard bad things like that its very hard to find something there . And I have to say that it was indeed very hard to find something but nonetheless I found a few fossils and it was much fun. I was firstly for about 3 hours in the visitor quarry Blumenberg. Here is the quarry: It makes sense to bring a shovel with you because you firstly have to put away all the debris before you can extract larger plates. The most common fossil there is the crinoid Saccocoma. Here are some examples: (about 2 cm big) Another very common fossil are coprolites from fishes/ammonites. They are called Lumbricaria: (3-4 cm long)
  14. Plant fossil from Germany?

    Hi folks, I found this in the Bavarian pre-Alps, and thought it might be a fossil, but I'm no expert. Your thoughts?
  15. I found two chunks of limestone from Madison group possibly lodgpole or Mission Canyon member. Take from upper belt Creek in Montana. At first I thought this was a coral. Is this a Bryozoan?
  16. Vertebrae? Waipara, New Zealand

    Forgive any inaccuracies, I haven’t hunted for fossils since childhood on the South coast of England so very much a novice. I found this whilst scouting out a new vineyard site in Waipara Gorge, New Zealand which is a pretty rich area for fossils (mostly Paleogene, and Cretaceous from what I’ve read). It was at the very top of an escarpment rather than the river banks where most are found and definitely in limestone, though I couldn’t tell you the exact type. There’s not much structure left to it (close up picture gives a better idea) but are these vertebrae and any idea what from? About 2cm diameter and 30cm in length. If anyone has any experience with this area I’d love to know more!
  17. Hi All, An acquaintance of mine noticed this fossil, embedded in a step stone in his parents’ garden, after many years it sat there unacknowledged... I don’t have a lot of information about it, but what I do know is that it’s in Israel, the stone’s origin is most likely from a strip mine 5km west of Jerusalem (Kfar Shaul), the total length of the fossil is 6.7 cm (~2.64 inches) and that it’s a limestone with a reddish hue… unfortunately that’s about it. Personally, I’m not even able to determine whether this is a fish or not… but I’m definitely curious… Can anyone help me identify it or at least narrow the options a bit? Thank you!
  18. I found this shell cast on Honeymoon Island, Florida, USA. As you can see from the photos it's a complete shell cast and measures about 4 x 3 1/2 inches. I did some research and found similar pictures that looked like Turritella Shell. Would the Forum agree with this ID?? If so I read that this is an extinct species of fossil sea snail. Is this correct? I appreciate your feedback. Thank you!
  19. excursion/field guide/IOWA

    here(lessthan 5 Mb) The Cedar Valley/Lime creek piece by some noted experts would seem to steal the show fig 3,with its correlation chart(useful inclusion of a Vail T/R* cycle chart!!!!) Figure gets better and more useful each time I look at it *Transgressive/Regressive
  20. Hello everyone, I will be going out for the first time to collect the lower Devonian Helderberg Group. I am wondering about which chisel and geology hammer are most appropriate for splitting the rock. Any help is appreciated. Joseph
  21. Mold Fossil of Shells?

    Hi, I'm a rock collector/hunter and found many of these shell imprints in limestone rocks on the beach. This one looked like a bullseye or pictogram. Is this considered a fossil? Does anyone know what type of shell and/or geological time period? Thanks!
  22. Fossil ID Ammonite?

    After walking 2+ years by the same spot, just noticed this, yesterday. It sparked an interest, but I know absolutely nothing about fossils. Is this a normal size for what I think is an ammonite? Found in Northwest Austin, Texas near the bank of Walnut Creek. I am assuming it’s limestone. Grandfather’s hammer is 37 cm.
  23. Graptolite?

    I collected this last year at Partridge Point (Alpena) Michigan. Middle Devonian. Thunder Bay limestone formation. Is it possibly a dictyonema crassibasale? Or merely a bryozoa?
