  1. Horn Coral in NW NJ

    Found this horn coral on Trilobite Ridge in the NW corner of NJ this past weekend. The 2nd picture is the back side of rock. Is it possible to identify the species with these pictures? Thanks, Mike
  2. I like to look for rocks in Tennessee (almost the Kentucky Border). This one I picked up thinking it was horn coral, but I do not see the normal markings on horn coral. I have never seen the "curl" on the end of any rock look this. Possible shell? Curious what everyone thought.
  3. Fossil Ore Finds

    Friday I returned to one of my favorite spots that soon will be developed over. Its for sale and I wish I could buy it. These are from the [Silurian] Clinton Group, Keefer Formation - locally called the Upper Frankstown Ore Bed. The white is calcite material. The red "iron ore" is somewhat pisolitic and some fossils are filled/replaced with specular Hematite. (which doesn't photograph well.) If anyone has any idea what the big flat "Scallop like shell"{414C. 414D} is I'd be interested in hearing. I enjoy the level of detail that is sometimes preserved.
  4. To begin with I am not an Ordovician collector, but after seeing recent posts from other FF members, I decided to stop at the St. Leon and Lawrenceburg road cuts in Southern Indiana as I was making my way to North Carolina. I will post picks without specific ids, I know I have bryozoans, brachiopods, horn corals- but no trilobites. I did find 3 things that look to me to be possible Cephalopods, but could be mistaken. I also found 1 other item that I have no clue to its I'd. Any help with these last 4 items would be appreciated.
  5. Help me ID this "rock"

    I found this many years ago as a child on a beach, either in Florida or North/South Carolina, but I'm not 100% certain. I always assumed it was maybe fossilized poop of some sort, or maybe even fossilized coral. The "rock" is very dense, can scratch almost anything(note glass), and is maybe .5-2lbs. I have dropped it onto concrete from approx. 3-5ft, and it chipped the concrete, and I at least noticed no changes to the "rock". No odor, not even when I originally found it. Non-magnetic. One Side of this "rock" appears to have a crystal-like structure/pattern, but going from the center to the outside. I've included pics: https://i.imgur.com/hmglsiL.jpg https://i.imgur.com/v0KFYv4.jpg https://i.imgur.com/dTiw952.jpg https://i.imgur.com/3QZqrfJ.jpg https://i.imgur.com/iJqIBYM.jpg https://i.imgur.com/SP3ykwU.jpg https://i.imgur.com/UWibNML.jpg https://i.imgur.com/Ory9WDp.jpg Yeah, after about a week of researching I'm thinking(like 85-95% sure) it's a Fossilized(?) Horn Rugose Coral. Looks very much like these pics on this page: http://woostergeologists.scotblogs.wooster.edu/2015/10/09/woosters-fossils-of-the-week-a-rugose-coral-and-its-encrusters-from-the-middle-devonian-of-new-york/ and it also looks very familiar to these/this pic(s): http://woostergeologists.scotblogs.wooster.edu/files/2015/08/3-Wanakah-corals.jpg The one pic I included( https://i.imgur.com/v0KFYv4.jpg) looks like calcite crystals I am also curious how old this item may be, and I think it's app. from the Ordovician to Late Permian era, so maybe 485.4–443.8 million years to 298.9–252.17 million years old. Any help is greatly appreciated, and thanks in advance!
  6. Penn Dixie Site - May 2016

    Here is a smattering of my finds from May 2016 up until last week! Good season already! I don't own an air eraser yet so I haven't done any detail prep work on anything yet. Small enrolled Eldredgeops
  7. Rugosa?

    I broke this out of a very hard chunk of Osagean limestone from Lawrence County, MO. The top disintegrated, unfortunately. There was a hole in the rock about the size of a penny, which allowed my daughter to spot the fossil. But that meant it wasn't protected from weathering, and as a result parts of the top were the consistency of rust when we found it. It appeared that the septa originally converged to a nice point. Is this rugosa? And if so, what type?
  8. I've been going through the fossils I collected over the summer, trying to identify them. I have a lot of horn corals, several of which look like they could be either Streptelasma ungula or Stereolasma rectum: Several of them have matrix filling the calyx and obscuring the detail. With or without that, though, I don't know how to tell them apart! Except that my fossil guide lists Stereolasma as potentially being a little larger. This only rules out a couple of my specimens, though. Can anyone tell me what the diagnostic features of both species are?

  16. Petrified Mushroom, Horn Coral, Or...?

    I found this on the shore of a lake. At first I thought it was a petrified mushroom. It looks very similar to a mushroom. But, someone mentioned it could possibly be a horn coral. I really have no fossil knowledge so I'm just interested in what this possibly could be. It's very cool looking.
  17. Horn Coral from Giles County

    From the album Silurian Fossils - Giles County Tennessee

    Stegerhynchus from the Silurian Period 443 million to 416 million years ago. The Rugosa, also called the Tetracoralla, are an extinct order of coral that were abundant in Silurian
  18. Very Large Crinoid Stems

    I revisited a creek Tennessee that I had mildly glossed over in the past. With more purpose this time I searched and found some of the most beautiful and large fossils I have encountered yet. As a crinoid enthusiast I was overjoyed, and even more exciting was all of the OTHER marine fossils I found, expanding my appreciation of all kinds of fossilized beauty. here are a few of my favorite examples and I may post more as I continue to photograph my finds.
  19. I'd heard this location had blastoids, which I've never seen before, so last Friday me and a friend headed down there. We arrived around 930 or so and were immediately stuck by the steepness of the cut "we have to go up this?". We got up near the top where the really productive layer is and immediately started finding blastoids, archimedes, and small horn corals. Most blastoids were in the 1/2" range, I found one archimedes that is around 6" in a slab. Buddy found one blastoid that is probably over 1". The horn corals are generally small. Lots of crinoid bits and pieces also. We took a break for lunch and when we returned we had company. On the west side there was now a man and his son. We hit the east side but it wasn't very productive. Dropped back down and the man & son were gone, but now there was an older lady with 3 young boys. We crossed over and said hi. They were looking for fossils on the very bottom layer, which is hard limestone and not very productive. The boys got very excited when they saw my rock pick and boots. I gave them some of the duplicates of everything I had picked up earlier. I told them the good stuff was up there. Things evolved and me and my buddy wound up taking the two older boys up the road cut to hunt. The boys were very polite, calling us "sir" the whole time. We spent around 30 minutes up high, with them finding several examples on their own. I ended up giving them my bottle of water because they were dried out. I was identifying what they were finding or debunking psuedofossils (lots of those when you're 10/13) the whole time. They eventually asked me if I was a scientist. Eventually grandma yelled up that it was time to go, so we had to get down. I think all the grown-ups were much more concerned about it than the kids. The 13 year old scrabbled down 3 steep 4' shelves in no time. But I slowed down the 10 yeard old, I was afraid he was going to fall. I ended up getting below him and lifting him down each shelf. He actually told me I was really nice. Overall a fun trip, if a bit short. It was made more enjoyable by getting to help stir an interest in science in some youngsters.
  20. Hoping For Fossil Id

    A friend sent me these pics from Val Verde County, Texas near the Edwards Limestone formation, about 17 miles south of the intersection of Highway 277 and Highway 55. Approximately 6-7 inches long and approximately 1.5 inches diameter at the base although oval not round. It is carbonate material, and looks like it was calcified. Any help on identification would be helpful. 1) 2) 3) 4)
  21. mikeymig started a thread a few weeks back that got me looking through my collection of bryozoan encrustings (does someone really have such a collection? I have a cabinet drawer devoted to them.) I posted several specimens. Looking further I came across an Ordivician speciman I'd had for several years and had never gotten around to cleaning, so I did. The further along I got the more fired up I got. Upon finishing I knew I had something special. There appears to be 2 different bryozoans on the horn coral. The process that took place for this to occur must have been amazing. [
  22. Horn Coral

    From the album Ohio Fossils

  23. My wife and I have been exploring our local Mississippian Warsaw formation. These are some of our less common finds from the Warsaw Formation on the Meramac River from the last two weekends. Meloechinus maltiporus Echinoid - Warsaw Formation- Mississippian Age Horn Coral - Warsaw Formation- Mississippian Age
  24. Recently a hill of dirt and rock has been pushed in front of the drive to keep water and washed out materials from gushing down the driveway and into the street. This was the first time in at least several years that this had been done. My first visit to the site produced probably 30 horn corals and brachiopods strewn just across the drive all the way down to the street, pushed there by the flooding caused by rainfall. Obviously, no one had been there in quite a while. The floor of the quarry has become “terraced” due to erosion. The terraces are at most 3 inches tall and may run up to 30-40 ft along the curved contour of the floor. Last month I visited for the 2nd time this year…. with the recent drought followed by several gulley-washer storms within a week’s time I had a feeling a lot of material could have washed out. I was correct. In 3 visits (Th-S-Su) I ended up with 65 lbs of fossils. Around half being brachiopods…. Herbertella, Platystrophia, and Lepidocyclus. (about half of the brachs found) Along with some decent horn corals and cephalopods. Often times a wide range of specimens would be clustered in a small area, such as in the photo below. What all do you see in the photo? Or, there might be a cluster of the same kinds. The brachs in the next pictures, were found clustered in each of their own 1 square foot areas. As if someone set them there. Just sitting right on top of the ground rather than stuck in the rock. At this time I don't intend to visit this site again until next spring, although I may have second thoughts if a huge storm rumbles through in the Fall.
  25. In 2011 a veteran rockhound (no longer in shape to go on field trips) in the Dayton Gem and Mineral club mentioned this no-name Ordivician site where he’d had a lot of success in the past finding fossils. I’ve visited the site about 5-6 times now and have never been disappointed. It has a constant erosion of horn corals, brachiopods, cephalopods, bryozoans. As I heard it, at least 20 years ago an entrepreneur bought a hill/hillside plot of land just within the Dayton, OH city limits, less than 2 miles east of downtown. Just on the edge of a commercial business area. (looking west) (looking north from the driveway) He immediately turned into a small limestone quarry. Within 10 years he ended his business and the quarry has seen little or no activity except for an occasional illegal dumping. The “Y” shaped quarry is entered by walking up an eroded blacktop driveway. The East “wall” is about 150 yards away, the Southeast “wall” about 75 yards, and the South “wall” about 175 yards. An apartment complex can be found within 50 yards beyond the SE and S “walls”. The far “walls’” base being maybe 8-10 feet higher than where the drive meets the quarry floor. The West side of the quarry is lined with trees sitting atop a 3-6 ft tall hill. The old business district begins just on the other side of the hill. To be continued....
