    Rookie / Newbie guidance

    Hi - I am not sure what I am looking at or if I should bother with these types of finds. Could anyone shed some light and provide direction? I am finding a lot of "large rocks" like this in small dried-up basins between hills. The area is close to the Harpeth River in Nashville, TN. Thanks for any advice in advance. My daughter and I like to go exploring and want to guide her in what we are finding.

    No Geological Information

    Hi, I don't have any information on this specimen since I believe the rock that I found it in is foreign to the area I discovered it. Although I think the rock is from somewhere around the Western Pennsylvania/Eastern Ohio area. It is approximately 2.6 cm by 2 cm. Just hoping someone has some idea what it is. Thanks again.

    Cephalopod or not?

    I’ve had this forever, I think I found it in Middle TN. I initially thought it was a cephalopod, but I know more now, and I don’t see any septum(s). What say ye? Thanks!

    Coral or urchin fossil maybe?

    Hi everyone, found this fossil in limestone area in United Arab Emirates which was formed 66-74 mya, according to local geology museum. Not sure what it could be but looks very pretty for sure This fossil was found on the ground in sandy areas where bivalves and small shells are found quite abundantly.
  5. Hey there Fossil Forum. One of my friends found an interesting specimen showing a well preserved (lamellar?) microstructure inside the Beauharnois Fmt limestone (Joliette area, Québec). Beauharnois Fmt is Ordovician. To me, this could very well be some kind of colonial animal (like a bryozoan or graptolith), but I have never seen a similar one where I live so far. The dual branch architecture makes me think of a graptolith, while the somewhat "lamellar" microstructure reminds me of a bryozoan. However, I would not be surprised if it was something entirely different. Any guess? Plea
  6. Does anyone know what this might be inside of this limestone? Found at Maskuta Creek, Alberta, a stream connected to the MacLeod River 4 km from Drinnan in the Hinton Valley

    Mid-Missouri creek find

    Hello! I am very curious about this find. Like the title says, this was found in mid-Missouri in a creek bed. There are a few hexagon patterns I can see that are connected but I truly have no idea what I'm looking at. Any ideas?
  8. I apologize in advance for the photo quality, and the fact that I did not have a ruler with me when I took the pics. I see these things EVERYWHERE. The ones pictured here are large (6-8”, 15-20cm), in limestone slabs. But I see them in smaller sizes, in rocks that I pick up. The rocks often have recognizable fossils in them, too: cephalopods, brachiopods, crinoids, bryozoans. I am thinking maybe these are internal structures, perhaps of brachiopods? I’m starting to think I am crazy…
  9. Last weekend, I made the trip down to San Antonio to tour and interview at a school. Though the drive wasn't all that long, it was enough for me to decide to take advantage of the opportunity and make a visit to one of the most famous Lower Glen Rose roadcuts in the Northern San Antonio area. In recent weeks, I have finally hopped onto the echinoid train and begun rapidly expanding my urchin collection. To keep the ball rolling, my goal was to find at least one decent specimen of Leptosalenia texana. Luckily for me, the layer I was heading to has been dubbed the "Salenia texana zone" for a rea

    Crinoid Matrix Removal

    Howdy! I found dozens of crinoid stems recently and most of them seem to have a thin layer of matrix attached. They were found in limestone, but I don't even know what mineral they've been fossilized in...calcite? Would I be able to remove the matrix with sandpaper and perhaps even polish them? Would sanding them remove visible segmentations? All help is appreciated, thank you.

    Any Chance Dating These Crinoids?

    I was searching around a local stream when I found some limestone with dozens of crinoid stems. I can't say what the formation is as I think they rolled down a hillside which had foreign limestone blocks to prevent erosion. If they are native, they would be Pennsylvanian Glenshaw Formation. Each of them has stellate lumens and many have a pinkish hue. Can anyone tell me what variety of crinoid and is it possible to discern the period? Thanks.
  12. A week ago I made the trip out to one of the roadcuts on loop 360. I realized that I had been neglecting visiting the west side of town which, although very different, is just as rich in fossil history as the younger east. I want to also thank @erose as he has posted lots of useful information on the cuts and what sorts of things can be found. I arrived in the afternoon and slowly climbed up the gravel to get to the first bench. I made the rare good decision to hunt on the side of the road that would shield me from the sun, making the temperature nice and cool, perfect for fossili

    Crinoidal limestone?

    Hello! Is this a crinoidal limestone rock? Dimensions are 7 x 5 x 1 cm. Wet: I picked it up in Braila county, Romania. A few hours ago. Thanks!

    Very Cool

  15. Please help me identify this item. Found part way up a wooded hill side in northern Missouri.

    Cretaceous Fish (Shark) Tooth

    Please identify this tooth Found in cretaceous, turonian sandy-limestone in Poland (Górka Pychowicka, Cracow). This rock is amazing, on left there's Ptychodus decurrens tooth too.

    Help with ID?

    Hi all, first time on here and I have a fossil that was found in South St. Louis County that I would love to get a potential ID on so I can learn more about it. Thanks for any help you can give me.
  18. I have a large piece of soft limestone from Lake Texoma. It contains an external mold of both a large and small ammonites. These are the first cephalopods I've ever found, and I'd like to preserve them. Any suggestions?

    What is this stuff?

    One of my local spots to fossil hunt has a lot of limestone (I think) with what looks like worms running through it. I see this stuff everywhere and have no idea what it is. The area is definitely Glenshaw Formation and has fossiliferous limestone and shale. Any help is appreciated.

    Never seen another like this

    Please help me identify this. I found it in my yard while digging up my garden. I'm located in central Texas. Thanks
  21. With time running out before the start of the school year, I decided to spread my attention across three DFW formations to get a little taste of what each has to offer. Instead of shooting out a handful of smaller topics, I've decided to combine my trips into a single larger post. I wouldn't say any individual find is a jaw-dropper or museum-worthy, but they, all together, give a nice glimpse into what each formation can yield. In order from oldest to youngest: Goodland This adventure took place in Oliver Creek with the Dallas Paleo Society. It's a regular s

    Limestone agate?

    I found this weird rock around limestone of Paleogene age near Khurais east of Riyadh Saudi Arabia. is it a agate? and how does it form. thank you all for your time!

    Found in late Cretaceous limestone chalk

    Hi all, hoping someone can tell me what these bits might be. The kids found them digging around/in a Cretaceous limestone chalk and greensand. Took them out there for a fun day, no idea what we were going to look for or where. Hoping someone can identify any of it. Thanks in advance
  24. Hey there, me again (since my first ever post had great success)! The photos I am about to show you may depict one or two different animals, found in the Neuville Formation of the Trenton Group (Middle Ordovician). The host rock would be micritic limestone and all pictures were taken in Neuville, 30 km west of Quebec City (Québec Province, Canada). Stratas had a subhorizontal dip, slowly sinking into the Saint Lawrence River. Today, I have 6 pictures showing 6 different specimens. The photos might be showing the same animal, but seen from the top AND the bottom (which

    Tube Structures--What are they?

    Found near the Whetstone Mountains, near Tucson, Arizona. I am very curious about the long, orange tube structures I found. Some folks told me they are just chert nodules. Others seem to think could be fossils. So, I took more photos to see if I can get more information on them. They were found right near some other fossils--fenestellid bryozoans, rhynchonellid brachiopods, gastropods. The area is littered with fossils. Several of these structures reveal a tube structure, which I think would be unusual in geology. A lot of these structures have a very s
