I have no clue what this could be. Not a trilobite, not sure if it's a rugosan. Age: Late Eifelian Locality: Southern Belgium Width: 1,3 cm Length: 1,5 cm

Hi everybody first time here.I found a bag of polished stones none bigger than a quarter.I don't know where there from but I'm in Colorado so i take them home and put some of them under a microscope that connects to my computer and this is what i saw.The rocks themselves are dark red almost black in color about 1/2 inch long by 1/4 inch wide and corkscrew like shape.What are these how could these things get trapped inside the stone like this.if anybody has an idea of what these are let me know.thank's

Can someone please help me identify what this may have come from? It was most likely found in South Dakota or Montana but I can’t be 100% sure. IMG_4025.mov

Hi, We found this fossil on the edge of a nearby lake. Can you please help me to identify it? It's about a half inch long. I'm located in Northbrook, Illinois, USA. Thanks in advance!

Here are three fossils I need help identifying. I found one from last year's summer and two from a couple years ago. Here is a possible goniatite/gastropod. Sorry for the bad quality of the images, but if you look close enough, there is a small ammonite-like shape that has been crushed. I'll see if I can get better pictures if you guys ask in the comments. Right beside the larger one is a smaller one that is facing opposite too it. Both are really flat and their spirals doesn't go all the way in. Their outlines are very hard to notice, not sure if this is a fossil or just some rock formation. A twisting cylindrical fossil that branches into two. It has cracks and resembles very much a coprolite. Might be a rock formation, but I don't think so. Sorry for the bad quality pictures. A little round cone with lines all over it coming from the tip. It is round and underneath it there are more lines coming from the outside. If you guys could identify these fossils I would be very grateful because I could not. I would be glad if these were what I assume they are because they are very rare in my area.

Hi, Anyone know what this is? Sorry have no info on it, not even provenance. No scale but based on the coin seems to be on the order of 10cm or less. Thanks.

I got this tooth and a few others in trade from a geologist in Southern Morocco probably close to twenty years ago. At the time he sent me a number of teeth, all identified as mosasaur. This one always bothered me with that id as it looks quite a bit different from the other mosasaur teeth. It has a more compressed oval cross section than most of the mosasaur teeth I have had in the past. It also appears to have a bit of serration on the edges. Supposedly location given to me: Timhdite, Morocco, possible Oil Shales The geologist was working for oil companies in the area at the time. I have long ago lost the contact information so can't contact him for further information. Also wondering about the color. All the teeth I got from him were pure black, reminding me almost of the California tar pit colors. Thanks for any help you can give me.

L.S., Hopefully the collective knowledge of TFF community will once again prove able to identify something that has stumped me. This time I need your help with these curious stem fragments! A good friend of mine purchased these at a mineral show on the US mainland. The specimens potentially originate from Kane County, Utah, but this provenance is far from bulletproof. It is quite likely, however, that they come from somewhere within the USA. The stems exhibit a hollow centre, with a ribbed internal surface (pith structure?). None of the specimens show nodes or other signs of axial segmentation, however. The cross-sections (both rough and weathered as well as polished) show seemingly regularly spaced vascular structures. The larger "pores", especially, are quite striking. Scale on images is in centimetres. If the Kane County provenance is correct, then a Mesozoic age seems likely. But, again, provenance is very much in question still! Has anyone on TFF seen this type of petrified stems before? Any information you could provide would be very much appreciated! Thanks, Tim

Hello, I have a whole bunch of unidentified crinoids I'd like some help identifying. From my guess on the species and the fact that there were all together (as well as the other specimens that came with it), my guess is that these are Pennsylvanian or Permian-aged crinoids from Texas or Kansas. I'm hoping narrowing down the ID would better pinpoint the provenance for them. Here goes. The calyxes all range from 1-2 cm wide. I did attempt to ID them, using resources including this by the forum's @Missourian: #1-#4 I think are all of the same species or at least genus. I'm inclined to say either Delocrinus or Graffhamicrinus, which are similar-looking genuses. 1. 2. 3. 4. 5. This one is a bit unusual in that it seems to have some arm bits preserved, which look like thick spikes. It's a bit crushed but I think based on the calyx pattern it could still be a Delocrinus or Graffhamicrinus. 6. This one has a basal plate pattern like Delocrinus or Graffhamicrinus, but has unusual spines coming off of the radial plates. The following 3 specimens (#7-9) look similar to the above calyxes, but I noticed they somehow seem more globular and rounded. They may be the same genus/species and just variants, or a different genus/species. For instance, if the above are Delocrinus, perhaps these are Graffhamicrinus? 7. 8. 9. The following four (#10-13) are clearly different from the above. Each has a clear infrabasal circlet and stem attachment, plus the calyx expands towards the top, which gives it a more cone-like appearance. These may be Bathronocrinus according to this: http://inyo2.coffeecup.com/kansasfossils/crinoids2.html 10. 11. 12. This one has some proximal arm bits still attached. 13. This next one has very bulbous/swollen calyx plates, which are especially noticeable from the side view. Perhaps a Galateacrinus according to Missourian's diagram? 14. 15. The plate structure is harder to tell on this one, but it has slightly swollen basal plates that form dimples/notches where they meet the radial plates. This is clear on the side profile. I honestly have no idea what this one could be. 16. This one has no plating texture, and I'm thinking it looks like the basal plate of the floating crinoid known as Paragassiocrinus, which is known from Texas. If so, and it is specific to Texas, perhaps I can attribute all these specimens to the Pennsylvanian of Texas as well. 17. An odd specimen, might be a set of basal plates. 18. This seems to be a stem and basal plates. 19. These seem like spines from the anal tube or "umbrella" of a crinoid such as Plaxocrinus (https://www.google.com/search?q=plaxocrinus&sxsrf=ALiCzsbwpZnGPNxgLHUJ4758h1D4GTNkKQ:1669188769957&source=lnms&tbm=isch&sa=X&ved=2ahUKEwjM5sjd5MP7AhWmKkQIHb3vAIkQ_AUoAXoECAEQAw&biw=1257&bih=764&dpr=2#imgrc=atyg4qzOxLWjRM). 20. I'm unsure if this is from a crinoid, but it might be part of a spine. 21. This one I placed separately because the color of the calyx and matrix are different from all the rest, and so it may be from a different locality. Species-wise it looks similar to the first 9 specimens I posted, so it may be a Delocrinus or Graffhamicrinus.

Hey guys I’m kinda new here. I found this fossil a couple of months ago and I need help identifying it. Any clue about what it is??

Greetings from Kentucky. Wandered across this forum trying to identify what looks like a fossilized vertebra I picked up roaming around with my nose to the ground. I've loved rocks ever since I picked up a huge chunk of fossilized wood as a little girl in Louisiana. Married into a family of stonemasons who used to drive into the creek and pick up the rocks for their jobs. They'd been masons for maybe 20 years and the first time I went to the creek with them I was the first of the family to find an arrowhead! Picked up all sorts of neat geodes and other pretty rocks through the years and have never stopped loving to pick little pretties. This thing was a big chunk that I thought was a geode. After dropping it into some vinegar to clean it up I was completely shocked to find this heavy fossil. Not sure if that little protrusion is some sort of barnacle or a tooth sticking out of it. Either way, this fossil is my pride and joy and would love help identifying it. Measurements: Front to back 6.5 cm (no spinous process) Left to right 5.5 cm Top to bottom 3.5 cm Weight 195.75 gm Feels a bit waxy. When picked up it seems heavier than it looks. Thanks! Michele

A guy I traded with gave me this possible dinosaur claw. I'm trying determine if it's a dinosaur claw. He said he was snorkeling in hell creek and found it. It's about 5 inches give or take. It's heavy and It has a blood groove on one side which only dinosaur claws have and the other has grooves or grains of bone like look and feel. It resembles a dinosaur claw and the patina on it, brown like, would be the result of being underwater for a long time. Please some help here determining this is a dinosaur claw or something else. Thanks. Brittan

Hi there. Wondering if anyone can help with this. strange story: Found it in a fossilized ash beach- and it had clear impressions on the exterior of suction cups kinda shapes. However the substrate wasn’t stable and was kinda falling apart over time. so… I put it in my kiln to IDK see if it would turn into a ceramic. Instead the top blew off and revealed a similar shaped but non aligned actual fossil. any help with ID appreciated!

I hope someone can help me Id this. I live in Southern Indiana in Spencer county and due to man made environmental issues my house has began to sink, as we are on an aquifer and when under the house trying to figure out if we could help stabilize the area we came across this turtle looking object. Before it dried it was connected from head to what looks to be a shell structure. I'm so lost to this as I haven't found anything similar yet. All help identifying appreciated.

I bought this fossil at a fossil show yesterday. Seller said it was a Starfish from Morocco. He had a few but only this one had another fossil next to it. He didn't know what it was. Does anyone know what is next to starfish? Was he even right about this being from Morocco? Also anyone know what type of starfish it is?

Here's a couple that I have no clue on ID. I'm asking the usual gang to help with ID, and anyone else with an educated guess. @connorp @fiddlehead @deutscheben @Nimravis @RCFossils @stats

This piece of incomplete fossil is from Yunnan, China. Same locality with Keichousarus, Triassic Formation. Any idea what is that? It looks like there are broken bones.

Hello, thanks for the first batch of fish scales yesterday. I!ve dug up a few more stuff from out storage room. This batch has some weird pieces. the first couple looks like some broken piece of... coprolite to me. The surface, the shape suggest some quite compact dropping, although that hole in the is odd compared to the crocodila coprolites we have. Poopstone or not? The second weirdo looks like a claw to me, but could also be a less perfectly conserved Onchopristis tooth? The third piece looks like some vertebra to my untrained eye, maybe somewhere around the tail end? And last but not least, the fourth looks like some bigger bony structure, but I have no clue what it could be. (Tried to shoot with super macro on my Mate 20 Pro, I hope you get the details.)

Hey everyone, Any ideas about what this could be? We found it on a beach shore in Acadia Michigan. It has so many features that makes me think it's something special. - Triangle shape - possibly single root lobe and root line on top? Was thinking shark tooth but doesn't have two root lobes or v shaped root/gum line. Also seems very old. Was also thinking dinosaur, but It's my understanding there are no dinosaur fossils in Michigan, so possibly very old? Curious to know what you think! Thanks.

Hi, i have this lot of shark teeth from France but their previous owner, who live in the department of the "Pas de Calais", had them since decades and doesn't remember nor where they where found precisely nor their age. Is it nonetheless possible to determinate them ? Your help is appreciated. The squares are a centimeter aside. The photos one and two show the same teeth. Idem for the photos 3 and 4. 1 : 2 : 3 : 4 : Cheers, Fifi.

Spotted this in a small bay on Anglesey, Wales. There were lots of other small shellfish type fossils mostly in slate rocks, but this one was larger and seems to have vertebrae? Could anyone offer any insight into what this is please? Many thanks.

I found this years ago off the beach in shallow water in North Miami with a bunch of shells. It is not metal. Won't give a whisper on a metal detector. Don't know if it is a fossil or not. No idea. It has stumped me for a long time. Any help appreciated. Thanks.

What is this? I pulled it out of the dirt. It has a sand like texture outside smooth on the lighter part. I have no idea what it is.
