  1. Possible fossil?

    Found this while hiking in a mostly dry creek bed in North West Arkansas. Picked it up because I thought it was interesting. When I first spotted it I thought it was a piece of bone. Seems very solid, no porousness in the center or striations outside. Is it a fossil of something? Just a neat rock?
  2. Tabulate Coral? Am I right?

    I need help identifying this one. Thanks
  3. Antler, Bone, Other?

    These 2 items were found close to each other in a creek bed in Northeast Arkansas near the Missouri border on Crowley’s Ridge. Because of the heavy flooding during the year that these were found, I organized my finds according to date. Every flash flood seemed to bring different oddities.
  4. Burrow, Bone, or mineralized iron

    Below are 2 items found on the same day after a few days of heavy rain/high creek water. Both of these are heavy and have a hard iron-like shell or covering. The 2nd item was split into 2 pieces when I found it. It is made of the same material as the first. We have iron in our well water at the base of the ridge so I’m very familiar with the color and the smell of iron. These items don’t usually wash up in the creek. I picked them up because their unusual shape and texture contrasted with the creek’s normal sand and gravel.
  5. Crowley’s Ridge

    All of my pieces come from a creek on Crowley’s Ridge in northeast Arkansas near the Missouri border. Crowley’s Ridge is believed to be about 10,000 years old. Located as far north as New Madrid, Missouri and as far south as Wynne, Arkansas, it is believed by some to be a former bank of the Mississippi River. At some point, it may have even been an island. Some research has suggested that the ridge was affected by volcanic activity in the distant past. Today, Crowley’s Ridge is known for its gravel pits, uplifts, and bluffs which were likely caused by the New Madrid fault on which it sits. Our roads are covered with Crowley’s Ridge chert from the gravel pits. More practically-at least for me and my farming family-the ridge is partially covered with fertile, wind-blown “sandy loam.” We are rice farmers at the base of the ridge. I have explored the ridge since I was very young. The pieces I have collected were strange or out of place according to my limited perspective. I should also add that Crowley’s Ridge is Home to flora (plants) that are so far unknown to the Appalachian chain to its east and also unknown to the Ozark chain to its west. In this way, my little ridge is very unique. Memphis State University has done research on (Cretaceous?)sea fossils found in a creek bank near Wynne, Arkansas—-near the southern end of the ridge. I haven’t found those kinds of fossils in the area where I’ve explored. I learned most of the above information in a couple of upper level geography courses I had to take to fulfill my degree in Social Science. I don’t pretend to be an expert in fossils, minerals, or geology. I am here to learn about my “cool” rocks and clay.
  6. Fossilized teeth ID

    Decided to take my kids fishing today at a creek we frequent sometimes. We were getting ready to start packing up and head home when I look down and see what I think is pretty colored rock partly buried in the ground in some sandy soil(I'm a rock hound, lol) Upon unearthing it i was surprised I had stumbled upon this pair of amazing fossilized teeth! The excitement is real and I've never found anything like this before! I have no idea what these are from but I'm sure sone kinda bovid. I'm also in South Arkansas btw if that helps any! Thanks!
  7. Not a Thunder Egg

    Hi guys, avid rock hunter here, brought home this “thunder egg” from crater of diamonds in Arkansas a few years ago. I finally got a slab saw and it’s not what I expected! It’s semi transparent in spots and some druzy inclusions. Some areas seem a little oolitic? Could it be an “agatized” fossil of some sort?
  8. Fish Skin?

    I was in my favorite creek bed for ammonites and nautiloids in a nice bed of Fayetteville Shale, when I found this fascinating little rock. I think I read somewhere that you can find fish skin in the lower Fayettteville shale? Whatever it is I've never found anything like it. It's about 2in long, .5in wide, 1/8in thick. There's a section running through it that looks like a core, but it didn't photograph very well.
  9. What is this?

    My son found this while on Boy Scout canoe trip on the Buffalo River in Newton Co., Arkansas. (6-2-20) Found in a river bed. Some type of molar tooth?
  10. Rock or fossilized bone

    I found either a rock or a fossilized bone in NW Arkansas along the War Eagle River earlier this year. The War Eagle Quadrangle https://core.ac.uk/download/pdf/72842749.pdf has sections that are Ordovician, Devonian, and Mississippian. That being said...is this just a rock? I don't want to state why I think it might be one thing or another....needing a fresh perspective.
  11. I don’t have a clue. Fern? Snake?

    I was looking at shale pieces that had some cool shells sticking out. I thought I would break the best piece off instead of toting the whole slab to the truck. I went to knock a chunk off and this was exposed. I first saw the snakeskin looking part and then I saw the red. I never would’ve know it was there if I hadn’t broke it. Can anyone tell me what it is and can it be saved? I think I managed to find the majority of the small bits. For reference it is only about 1.5in long. I ended up toting the whole piece back. Now I gotta see if it was worth it.
  12. Concretion Fossil ID

    I found this over the weekend. I’m trying to figure out if it’s a fish vertebrae or something else. It appears to be coming through on the other side as well (3rd picture). I’ve included some pics of other fossils in the same rock. I’m sorry for size reference. I don’t have anything in millimeter lengths laying around. Thank you all.
  13. Please help ID this little guy

    Hello folks. I'm back after an extended break. I've found some really cool fossils on my land in southern Missouri, Texas county, USA. Just a few miles south of cabool. A seasonal stream flows through my land exposing some cool finds, not to mention- the heavy rains are washing the topsoil away. From the hundreds of artifacts I've collected, this spot must have been an indigenous settlement. My best guess is that this item was in the hands of those early Americans. I can see why, this is my 2nd most favorite of the collection. Please help me identify what this is. Any help would be greatly appreciated. FYI, I have overcast skies at the moment and very limited internet access. These pics are the best I can do. Mm measurements are roughly 66mm x 38mm x 25mm
  14. Unidentified spiral fossil

    Three different people have posted what I think is a very similar if not the same fossil. In my original post I said it was Mississippian. However, I did purchase it from a dealer that described where he found it. I was not there. He was elderly at the time so there could have been confusion. I think he has passed now, so no way to know Let's assume age is unknown. Here are the other postings. https://photos.app.goo.gl/BCMTpriMfuSoaCi79
  15. I was at a creek bed today looking for stone points and artifacts. I found these two fossils Any help IDing them appreciated.
  16. crinoid ?

  17. crinoid & ?

    found this today on my land in Missouri. crinoid on left and something else on the right??
  18. bone or tooth?

    Hello. I spent a few hours looking around my land outside of Cabool, MO. I found some fossils, but first- is this anything cool?
  19. yesterdays finds

    Hello again. I found these yesterday. The clam is a dead giveaway(correct?), and the one on the top left is a coral, I'm guessing. What about the rest? Any help would be great. You see, I'm a carpenter. If it were a piece of dimensional lumber, I could ID it by smell and feel alone. hahaha
  20. Please ID this

    Hello from the heart of the salem plateau. I bought 20 acres outside of Cabool, MO. The plot has a few deep cuts exposing a lot of marine fossils, minerals, and such. This specimen doesn't look like anything I've seen thus far. Please help me ID this guy. Thanks and Season's Greetings.
  21. Vertebrate?

    I found 2 of these when I put in a septic system along with crynoid calyxs, nautilus, and ammonite peices. Wouldn’t expect to find anything like this here.
  22. Horse or Bovine Tooth? Approximate Age?

    I found this tooth last week in the Illinois River in NW Arkansas. I’m guessing it’s not terribly old, but I’d like some help narrowing down if at all possible. I think it’s a horse, but not positive. It looks as as if it has been buried in the mud at some point due to the dirt being up in the root. Thank you for any help given.
  23. North Arkansas curiosity

    Hi, this is my first post, very new to fossil/mineral collecting. Does anyone recognize this portion of what I believe to be a fossil? Pic 1 is what I am calling the top. pic 2 is a close up of an interesting portion of the top. Pic 3 is where the top and bottom wrap around the side to meet each other at some kind of a "V". Pic 4 is what I am calling the bottom. My in-laws are building a house in North Arkansas, I found this in the excavation. I have already identified coral, stromatolites, Shells in other rocks found in the same piles. The main minerals found are quartzite, chert, red sandstone, red clay, calcites, iron, zinc. The area they are found appears to straddles these two regions according to Arkansas geological maps. The house is being built on the top of a large hill: https://www.geology.arkansas.gov/docs/pdf/geology/Collecting-Fossils-in-Arkansas.pdf The Salem Plateau: contains the oldest rock present and is made up of dolostone, limestone and sandstone of Ordovician age. Algal structures called stromatolites, corals, brachiopods, bryozoa, crinoids, gastropods, and some cephalopods are the fossils most commonly found in the limestone and dolostone. Trilobite fragments are less common but are present in these strata. The St. Peter Sandstone contains the vertical trace fossil Skolithos. Silurian and Devonian strata are limited in their outcrop area. Silurian limestones contain crinoids, trilobite fragments, and small algal mounds. Devonian strata are usually unfossiliferous. The Springfield Plateau: is made up of limestone, sandstone, shale, and chert from the Mississippian Period. Corals, bryozoa, brachiopods, crinoids, bivalves, cephalopod, and gastropods are common in these rock types. Trilobite fragments are less common but are present in these rock types as well. Echinoid fragments are present in the Boone Formation. Starfish and bivalve resting traces called Asteriacites and Lockeia respectively, and worm trails are common at certain localities in the Batesville Sandstone
  24. 3 Day Trip with my girl

    Hi Folks, I am planning out my first long road trip to collect with my youngest daughter for next week.(she's 13 and we have our local Pennsylvanian rocks we collected together for years, but I have been overseas working for a year, and I am getting ready to go back to do one more year, and I want to do something fun with her and she asked to go look at rocks and collect since she knows it's my favorite thing I never get to do) Anyway, I've been out of country until about 2 weeks ago, and I know there's been a ton of rain in Oklahoma, and I am curious if I should try to head to Mineral Wells and Jacksboro in Texas, and maybe head back towards Arkansas, or should I head north to Kansas and maybe cross over into Missouri. I'm at a loss since I don't get much US news in Vietnam, so I have no idea what everyone's weather has been like, and I'm not looking for honey hole suggestions, just a few places I can take her that she can find stuff and we can just have some time together. Pay sites are okay too if you have some suggestions. Thanks, Jim
  25. Petrified wood or ???

    Hi everyone, I enjoy finding agates and fossils along eroding sections of Crowley's Ridge, a ridge of glacial deposits that runs through eastern Arkansas into southeastern Missouri. I appreciate your help ID'ing this chunk of something. As I recall, it's around 15cm long, around 7cm wide. I'll measure it tonight. Most of the petrified wood I find along the ridge is very dark: predominant colors are blacks, browns, and dark reds. I'll include a couple of samples in a picture below Both of those specimens are 7-10cm across. Both look a shade darker in "person." This is light to medium grey (just a shade lighter than it appears in the pics). The growth/deposit rings look interesting. Any thoughts? I appreciate all information/opinions on the grey chunk or the two smaller pieces.
