  1. Lingula brachiopods

    Could these be Lingula Brachiopods? If not, what? Thanks Greg
  2. Coral or Sponge?

    I found this yesterday during my creek walk. It appears to either be a Coral or Sponge atop a Concretion. It also has the "mud" on top which is fairly common...but it's very hard. It was found between the Upper Tully and Lower Tully formation which are both Limestone, between is black shale. The diameter on top is approx. 10"-12" and the reveal of the side is approx. 6". Thanks Greg
  3. Coprolite or concretion or ?

    Good morning all ive never found coprolite as far as I know. I’m wondering if either of these two are. If so, of what and if not, what are they? Note the hair or fiber of some sort in the lighter colored one. As always, thank you for sharing your knowledge
  4. trying to identify another find

    The front, back, side and bottom of whatever this could be? I could not find anything to measure it with but for now hopefully the pictures alone help for the meantime. The shape of it reminds me of a bone for some reason so that's my guess as to what it could be; not quite sure of what this texture on it is though, i scraped a bit of it off fairly easily and it was dusty brown coming off of it, but not too hard when scraping the surface it barely had any resistance. I tried scraping the exposed part of my other find; the iron concretion to compare the 2 and the concretion was much more durable on it's exposed part to try ruling out if it is just another ironstone concretion. It was found in the same brook called "big brook preserve" in central new jersey in the united states. Another possibility that I've came up with is that this find might be a concretion but not nearly as old and formed yet. Right now it could be anything. Thank you to whoever responds and helps with this post; very much appreciated.
  5. I have my first good scribe but have been so busy I've only really worked on my "sanity crab" Anyway - to all you beginners - dont do what I did - just commit. I started with an electric engraver, then I got a CP 710 engraver and now I have a 9361 clone - It ROCKS! Here is my new victim... I honestly thought it would fight me but I was surprised... I'll give it a few more hours...
  6. My biggest Tumido crab yet!

    Well I started my next project tonight, and compared to the last one, this one is so much fun (so far ). The rock is softer and it also peels off the shell beautifully. Things are going to get a bit more complicated I can see already as there is a thick layer of powdery calcite around the edges. I originally thought it was shell and I’d stripped off the shell the whole time But I checked with the scope and it’s calcite. Some before pictures. The concretion is 24 cm (9.5 inches) wide. The claws were already exposed like this, I found it wedged in between 2 rocks facing me like this! The big claw exposed section is 8 cm (3 inches) long, so the big claw will be at least 16 cm (6 inches long)!
  7. Egg?

    I know there are tons of 'not an egg' look alike rocks but as they don't seem to resemble this one I will venture to ask...my daughter found this in a shallow riverbed on our camping trip last week to central Connecticut. The brown shell like pieces are thick and uniform. There are some in the opposite side as well, will upload more pictures. This pic was taken the day of the find. Any insight would be welcome. My daughter is 4 and pulled it out because we were discussing all the different colors of the river rocks. This one looked nothing like the others. A man we had chatted with the day prior lives close to the riverbed and had spent the summer doing a lot of rock stacking and moving lots of the river stones around to build these rock nests in the water for his toddler to play in. A lot of the areas we were wading in were spots he'd been uncovering and relocating rocks. ANYWAY - any comments are welcome. Thanks in advance.
  8. 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
  9. 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.
  10. 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.
  11. Concretion 5: Fish Cartilage

    From the album Muncie Creek Shale Nodules

    One of my larger concretions and personal favorites
  12. 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:
  13. 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.
  14. 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
  15. 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!
  16. 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.
  17. 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
  18. 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
  19. Is it concretion ?

    Hi I would like to ask if this is a concretion? The age should be Ordovician
  20. 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.
  21. 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
  22. 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?
  23. 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
