  1. I had polished a number of these fossil bearing cherts. The were studied in a paper Paleozoic fossils of the Jersey Atlantic plain, by authors William and Ardis Kuehne. It was determined that these cherts were brought by rivers erroding fossiliferous limestones in the new jersey and new york ridge valley areas and ended up here on this beach with the famous Cape May diamonds (clear quartz) I had these tumble polished by my friend Leo Thomas. I am posting some finds. If any one has more detailed experience with identifying bryzoans and other things from the Ordovician to devonian period please help me out. The last two picture show an odd black piece of what?? Thanks Fred Flinstone.

    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 similar shape. Many of the tube walls seem to have a similar and uniform thickness. Most are about as thick as a finger or thumb and range from 4 to 18 inches long. They could be much longer but there's no way to tell as they are broken at the ends. There are dozens of them in the area. I really have no expertise and I sure don’t mind anyone telling me I’m wrong. But I wanted to give you an idea of my thinking. Please let me know what you think--thanks. #1 shows a typical one #2,3,4 show the far ends of #1 #5 shows another one with a hollow tube structure #6 and 7 show two other structures # 8 shows a far end of #1 #9 shows another structure end #10 shows two that seem to be crossing each other
  3. Stumbled upon interesting "imprints" and "casts" in one of our backyard landscaping rocks (Houston). The landscapers call it "Bull Rock"... I think it is actually "chert". Looks to be marine invertebrate fossils? Would that be common or rare in this type of rock? Wondering if it is worth searching more in the back yard?
  4. Hi! I found this very large and irregularly shaped flint nodule on the Thames foreshore, London. To me, it kind of looks like the branching arms of a sea sponge, but I have heard that flint nodules also sometimes filled the shape of animal burrows and other things. It has a number of holes/handles in it. What do you think it is?

    Strange flint fossil

    Hi! I found this strange piece of flint on the Thames foreshore. Is this a fossil sea sponge? Thank you

    Fossil find in Yellow Jasper

    Found this in the ‘Golden Gravel’ in our garden. Source unknown as it was here when we moved in and rock ID’d (using an app) as Yellow Jasper. The closest thing I’ve been able to find for the fossil is Hamulina or Toxoceras (last image), but not been able to find any mention of this being found in Jasper. Any ideas?

    Is this stromatolite?

    Hi! Is this a stromatolite? I picked up this rock on the premises of the Teleajen oil refinery in Prahova county, Romania. I have seen a chert wedge in a limestone boulder once upon a time, but this stone is different. It has layers of chert and carbonate, right? I grinded and polished the stone. Here is a close-up from the carbonatic area (fizzles with acid): Any idea how old are these rocks when found in S-E Europe? Thanks!

    Mudlarking the Meramec River in Missouri!

    Hi everybody, I'm a neophyte to the geological realm (especially regarding paleontology), but I thought I'd share some finds on the forum. In Layman's terms, I found some clams, possibly some coral, and (...wait I know this one) Crinoids! Any possible fossil ID would be great, happy to be here, and glad to join a community with similar interests! All items below were found within 100-200 yards of each-other on the Meramec river just outside of St. Louis, Missouri. 1) 2) 3) 4) 5) 6) 7) 8) 9) 10) 11) Artifacts:

    Fenestella sp.

    From the album: Missouri Bryozoans

    One of my favorite finds due to how its almost complete and is in a very hardy rock I am assuming to be chert
