  4. This Missourian is headed out to the Late Devonian of western New York state and Pennsylvania this coming week and hoping for a little help from y'all on localities for eurypterids and the sponge Hydnoceras. Are Clarke's (1920) Hydnoceras localities at Brown Hill (near Cohocton, NY) and Irish Hill (near Bath, NY) still productive and accessible? Are Ehlers' (1935) eurypterid localities at Bush Hill (near Smethport, PA)? Or are there other spots I should be checking out? I understand that the Trimmers Rock Formation in the vicinity of Bloomsburg, PA, is also worth a look for eurypterids, but I

    Guadalupe Mountains National Park

    I found this a few years back near (but not in) Guadalupe Mts National Park. Is it a sponge, coral, algae, or something else? Piece is about 6 inches across. Thank you for your help.
  8. Hello, I purchased this specimen a few months ago at an estate sale. No label, no information. The fossil has been split lengthwise, polished, and the interior void space looks to have been filled with a sort of yellowish epoxy. Each half measures approx. 4.75 cm long x 2.5 cm across. Original depth before cutting looks to have been around 2.5 cm. I believe it is a Turritella, in a distinctive layered, calcareous concretion. I was able to find a photo of an almost identical specimen on a college professor's website, but I was unable to get additional information after following

  12. This fossil was found by a friend near Falls of the Ohio, so presumably Middle Devonian but who knows. The hollow elements are straight, with angular cross-sections, and seem to be organized in alternating orientations. Any and all insights appreciated. The coin is an American quarter dollar, about an inch (24.26 mm) in diameter.

    Possible fossil coral

    Fossil forum, This is another fossil from the Leighton Fm haul. I was thinking coral, because of the external mold of it, but the internal mold has interesting segments. Unfortunately, the internal mold is missing a piece. Here are some pictures (internal mold on the left, external on the right):

    Unknown invertebrate fossil

    Fossil forum, Good morning. I recently found an interesting fossil invertebrate. It was found at the Leighton formation, Maine. I was thinking possible coral, but the segments on it were perplexing. Trilobite didn't seem to fit because of the size and the shape of the segments. Any help would be appreciated. Here are some pictures of it (the internal mold is on the left, external on the right):

    Hey everyone, I recently got a bunch of stuff from Mazon Creek, which I have zero experience with. I would really appreciate some help in identifying this stuff, so here's a few of the things. Everything is from Mazon Creek Pennsylvanian in siderite concretions, the scale bar is in mm. The picture labels are what came to mind looking at them. Thanks Everyone!

    Silurian Invertebrate Needs ID

    These are two fossils of the same species collected at the Long Pond Road Site along the Erie Canal in Greece, New York. They are from the middle Silurian Rochester shale. These were collected last winter, and I have since been unable to identify them. Both are no greater than 3cm in length. Some interesting fine detail is visible on the first specimen. The American dime is 1.8cm in diameter.

    Invertebrate ID help requested

    All, This is my first post, although I have been reading with interest for some time. As I approach retirement, I find myself returning to the hobbies of my youth, including fossil hunting. I found these fossils in a single rock in Northeastern Oklahoma (a few miles South of Tulsa). It came from demolished concrete structure, so I do not know where the rock originated. The rock is very hard and very fine grained. It reminds me of chert or a very hard limestone. The first photo shows one end of the rock, where the closeup photos were taken. The fossil in the upper left is about one inch (2
