    Geodized fossils?

    Hi folks, I ventured out today and found these in a creek in Monroe County, IN. I've seen (what I think were) geodized fossils at a local show in the past, so I was keen on trying to find some of my own. Attached are some photos. I think one is a geodized horn coral, while the other appears to be a crinoid calyx or blastoid. There is a small horn coral in some of the photos as a reference. These were somewhat common in the creek. I'm not really concerned about species here as they are fairly distorted, just interested in hearing if you think these are, in fact, geodized fossils.

    Rugose coral or nautiloid shell imprint?

    Here's a find from last summer. I originally classified this as a nautiloid, though I think it could be a horn coral too. Unfortunately I'm not very familiar with the inner workings of either and I can't see much that could point one way or another. I do think it's a nautiloid judging by how straight it is, but I would appreciate feedback from anyone with more experience.

    Hoooooooooooorrrrrrrrrrrraaaaaaayyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Here we are at last, into Adam's Silurian. Thanks for looking. First up is the Lower Silurian or Llandovery and I begin with a problem. I posted this one incorrectly in Adam's Ordovician as it had got it's label muddled up with an Ordovician Favosites I had that has vanished in the move here, but is being replaced by kind forum member @Herb Anyway, this, I remember now I've found the correct label, is from the greenish Browgill Formation, part of the Stockdale Group from a cutting near Skelg
  5. Day Two ; Locality One (or Six if you include Day One) Black Sahara, South of Erfoud 20th February 2019 Well this is where things really get interesting, so stick with this thread as there are dozens of photos of fossils coming up. Looks at the tags if you want clues. I was up bright and early and wandered out at about 7 am to watch the sun rise over the still mighty Erg Chebbi dunes. And as night's candles were burnt out and jocund day stood tiptoe over the misty duney tops, the chaps came to join me and managed lots of photos. Here's one, if you w

    This one is big!

    This one was found about 1 meter under the soil in Hidalgo County NM while digging for irrigation piping. The area is from the Maastrichtian epoch as far as my research has lead me. It was found directly beneath the soil where my " ocean dwellers" post was found. It's very heavy for it's size, maybe 40 lbs or more. I have spent many hours with this monster perched on my lap and with small tools and nylon brushes (very very carefully)trying to reveal as much as it shows.

    Port Huron, Michigan trip

    I drive 8 hours with a friend to a location he remembers from his childhood as yielding a lot. Oh boy it did. 100% worth the drive. Lake Huron, among the agates, pyrite, yooperlite, has some extraordinary Devonian fossils. All fossils were collected from the beach of his family’s property except for the fenestelid bryozoan, which was found at a gas station on the way there. please enjoy this collection of gastropods, petoskey stones, various tabulate corals, crinoids, stromatoporoids, bivalves, Brachiopods, tenteculites, horn corals, an unidentified agatized fossil in jasper matrix

    Horn coral or bryozoan colony?

    Found in landscaping gravel at a gas station on a 6.5 hour drive to Lake Huron for some fossil hunting. This is probably Devonian. Instinct tells me horn coral but it looks rougher than that and lacks visible septa at the top. Bryozoan colony? That’s my next best guess. Thanks! Love you guys.
  9. Hello all – Stumbled across this great site/forum after rekindling an interest in fossils and minerals from my youth. I was able to visit a spot I spent a lot of time in summers as a child with my own children and looking to get them interested as well. Location: Southern Ontario on Lake Erie After doing a little research, according to this map (https://www.geologyontario.mndmf.gov.on.ca/mndmfiles/pub/data/imaging/M2544/M2544.pdf) from the Province of Ontario’s Ministry of Northern Development and Mines, the bedrock is Middle Devonian (from the Detroit River Gp.; Onondaga Fm. –

    I found this in a small creek by my house can someone help me know what it is
  11. Hey fossil people... more specifically hey Arizona fossil people. I'm wondering if any of you have run across fossilized horn coral in this state? If you have, tell me about it. I'd love to see examples of what you've found. I"ve found lots of brachiopods and other marine life in Arizona but this is the first time I've found horn coral. The idea that Arizona used to be underwater is fascinating to me. Theyre not the prettiest specimens... but i found them and they're mine! Lol. For those wondering, I found these near Payson Arizona. Same place I've found byrozoans, brachiopods, and

    Some Kentucky finds.

    I went to a locale in Kentucky I'd heard about and did some hunting for blastoids, which I had never looked for before. After about an hour I came away with a bunch of crinoid pieces, some brachiopods, some random bryozoan pieces, a few horn corals, what may be a gastropod, and a bunch of blastoids of at least two different species. On to the pictures. I also included some random odds-n-ends at the bottom. A pile of fossils. Some of the more interesting crinoids. The three on top have some pyrite encrustation. The four on the bottom are interestin

    What kind of horn coral is this?

    If it even is a horn coral? Not sure if it’s possible to tell from this. Found on Lake Erie in Erie Pa. Thank you.
  15. On our trip out to some Rocky Mountain states this past summer, we found red agatized horn coral in the Uinta-Cache National Forest. Back home, we polished the agate, which is jewelry-grade material and transparent--so real agate, not jasper. Here's the video we created about our trip. Lloyd

    Silurian/Devonian horn coral?

    A friend gave me this ... horn coral? collected somewhere in the vicinity of Springville, Iowa, just northeast of Cedar Rapids. Macrostrat has that entire area underlain by Silurian to Devonian marine carbonate rock. Would be nice to confirm it's a horn coral, and perhaps get a more specific identification. Ruler marks are cm. It will be difficult for me to get a deeper macro with the camera I have, unfortunately.

    Fossil from my Great Grandma

    Hello, this is my first post as I stumbled upon this forum attempting to research a fossil my Great Grandmother gave me some years ago. When I was younger, I thought they were teeth of some sort, but after some digging (no pun intended), I am thinking it may be horn coral!? Also, in the second picture I labeled part of the rock #4; it appears to be different from the rest of the rock. Some of it is like a milky matte material and beside it (hard to see in still picture) is a section that glimmers in the light. I wondered if it was some sort of crystal or just another form of a fossil/the limes

    So reading through some old posts and seeing @Jeffrey P finds, I decided to get out today and take a trip to the Dave Elliot outcrops. After digging through what Jeff left behind I decided to take a look around that area. I’ll post more as I get them prepped but here’s a few to get started. Largest intact Horn Coral I have ever found.

    Crinoid? Cephalopod? Other marine life?

    Hello all, and thanks for being here! I am looking for an ID on these fossils for my own gratification! My focus is in archaeology, so I come across fossils often during surface collection adventures! A little about the location: These were found in Nancy, Kentucky, USA on a partially man made flood-control lake called Lake Cumberland (Cumberland river basin/Cumberland plateau). The banks are rich with small to medium chert concretions, fossiliferous sedimentary stones, and small to medium iron inclusions. Preservation of these specimens are, generally, fair to good.

  21. Here is a E. rana fossil I found at Penn Dixie the year after I started collected fossils in 2015. It shows clear evidence of having been partly crushed by a horn coral on pleurites 5 through 10 only on the right side. The curvature of the thorax elements support this interpretation as well as demonstrate remarkable flexibility. This is a specific event that must have taken place shortly before, during or after the demise of the trilobite, while it was still malleable to be so contorted. Pardon the poor prep, I used a sewing pin in a pin-vise to clear away matrix. All images are the same speci
  22. I had the opportunity to visit another Silurian site in the northern Georgia/southern Tennessee area. This is now the third such site I've visited, but the first in the Rockwood Formation as opposed to the Red Mountain Formation. As far as I can tell there's very little different between the two lithologically and paleontologically, with the Rockwood and Red Mountain occupying pretty much the same stratigraphic position. The difference seems to be that the TGS prefers to use the term "Rockwood" to describe it's Niagaran Silurian system and the GGS and AGS prefer the term "Red Mountain", mostly

    From the album: Lime Creek Devonian Rockford Iowa

    For now I'm just generally identify as Homalophyllum. And some people said they have trouble finding horn corals but for some reason as this massive pile shows, they're easy for me! SW corner are some largest and smaller specimens. The larger ones are easier to find and thus are the rarer while one inches and less seem to be the hardest for people to find.

    Payson Arizona corals

    Some more fossils that I acquired from fellow members of the local rockhound club, a couple who spend their Winters down there (except this past Covid year). I've got the location info but not the accurate stratigraphic info nor IDs. These are from two different locations in the Payson area. According to the maps in Gem Trails of Arizona (which the couple used to find the sites), the horn corals are from a spot along a road on the way to 'Agate Mountain', and the colonial types are from Houston Mesa, "right at the top of the hill". I don't know if the two locations are the same formation, or..
