  1. What is this?

    I have no idea what this little object is. It’s not wood, not man made, not a concretion as far as I can tell. Half inch long & found in big brook
  2. Liesegang rings?

    At first I thought it might be the cross-section of petrified trunk but upon a closer inspection, I doubt it's petrified woods. It is not silicified. I wonder if it's a concretion or Liesegang rings? I don't think I have seen something like this in person before. I couldn't get it extracted because it's embedded in the bedrock.
  3. Location: Missouri Geological time period: Pennsylvanian Formation: Muncie creek shale I believe it is some sort of cartilage or fish material but I honestly have no clue.
  4. Concretion 5: Fish Cartilage

    From the album Muncie Creek Shale Nodules

    One of my larger concretions and personal favorites
  5. Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale Found this very small tooth like structure and was wondering if anyone could confirm if it is a tooth or not. Normally I can identify teeth if they are large enough, but this specimen is very small. I have found teeth before in these concretions but much larger such as a possible Symmorium or Glikmanius along with a tooth from a member of Eugeneodontida. Here are some images I edited that might make some details more clearer:
  6. Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale I assume this could be some part of a fish, as I have found other parts of them inside a few of the concretions from the Muncie Creek formation such as cartilage, or it could be some sort of crustacean part but I do not know what this one could be.
  7. Drum fish or concretion or ?

    I’ve had these in my substantial pile of ??? I saw a recent post that looked similar and pulled these three out. Roughly 1/4 inches. Are they drum fish or concretions or ??? Thank you
  8. Fish Spine Fossil? ( Missouri )

    Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale I was cracking Phosphatic concretions and this baby popped out! I was excited and thought I should share and ask what it is! I believe it is a cartilaginous fish spine, but I have little knowledge in such topics. Ps Information on good glue to glue together the cracked piece is welcomed!
  9. Ironstone fossil?

    Is this even a fossil? Ichnofossil? I'm stumped by this weird pattern. I found this ironstone in my parents' gravel driveway. Gravels were recently obtained from the local sand pit company here in Salina, KS., so I'm pretty sure this stone was transported in the river from Kiowa or Dakota formation (Albian) before being deposited.
  10. 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
  11. 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
  12. Is it concretion ?

    Hi I would like to ask if this is a concretion? The age should be Ordovician
  13. Small concretion, what's inside?

    Hi! I opened up this small concretion this morning. It looks like there is something inside, but I just can't make it out and I guess it could be anything really. Maybe some of the more knowledgeable people can see something. Was found in an area where I have found an ovulate scale. The concretion is blackish while the matrix it was in is a light Grey.
  14. Coprolite, concretion, or scute?

    Hi there! These two rocks were found in the Aguja Formation. Wondering if they could be coprolite, concretions, some kind of scutes (unlikely), or meteorites? Material from the Aguja formation is very foreign to me, so I’m at a loss! They are rounded at the top and flatter at the bottom. Found amongst very large dinosaur bones. Thanks very much! Lauren
  15. Fossil bone?

    Something that looks like a fossilized bone. Got it out of a rock I split open, the rock in the pic with the green arrows pointing to where I extracted the thing in question. Any ideas?
  16. ID-concretions?

    I found these in a creek near taughannock falls (Tompkins county, NY). Are these concretions? Do they possibly contain fossils inside? Thanks! 1. About 25-30 cm in diameter 2. About 40 cm in diameter, with an interesting protrusion on a side
  17. Upper Cretaceous oddity

    While out in the Puerco, I smacked open a concretion to find an unfamiliar pattern. Any thoughts or ideas are greatly appreciated. The specimen is from the Upper Cretaceous (Turonian) Carlile Shale. It is layered and each layer has this pattern. I currently do not have a measurement but will do so. Thanks for taking a look.
  18. 'Spikeball'

    I'm guessing it's an iron concretion and not a fossil, but I would like to make sure. I have never seen anything like this shaped like a spikeball or flower, except in crystals. Fossil or not, I took it home because it's so interesting! Dakota formation and early Cenomainian. This formation are known for fossilized plants, leaf imprints, and petrified woods.

  19. Purse state park find

    Found in Purse SP, Maryland . Need help identifying
  20. What is it? concretion? egg?

  21. Please help identify

    I live in Northwest Indiana and my mom found this concretion. One side of it is fossilized though and has these indentions in lines. Any help identifying would be greatly appreciated. Thank you.
  22. Just some of my concretion landscaping. They were all found in Middle Tennessee. I’m curious what other kinds of fossils may occur in them besides gastropods? I have found several that nature cracked open containing Gastropoda.
