  1. Found several of these on a beach in Grand Marais, MN on Lake Superior. The light colored part is a bit rougher feeling and the red/maroon knobs or nodules are quite hard and smooth and raised. I can’t find anything on them…someone mentioned in another forum possibly Rapakivi Granite or Granite Mica Schist but I think they seem a bit different than the images I saw of those. The largest one has a few tiny pockets of crystals. Thoughts?
  2. In parts of the Severn Formation in eastern Maryland, I will periodically find layers that are very dense with nodules. Has anyone else noticed something like this?

    Braceville Mineshaft Question

    Hi. I was planning to take a look at the Braceville Shaft Mine site this summer, ... can the public access it?
  4. I am located in Central New Mexico. I have picked up several of what I believe to be nodules, fully calcified. A lot of what I’m seeming are the teeny tiny beads of crystals all grouped together, I hope you can see the detail. I am very new and I am trying to learn the best way to prepare and clean them. The specimens I seem to find are coated in multiple layers of various sediment, making identification difficult. I believe I see sutures around the circumference of the nodule, in a spiral-ish pattern, the sutures seem to have a zipper/teeth look to them. When I try to open them, carefully, slowly….they just chip away. I didn’t want to try anymore to I hopefully don’t do more damage. I need……..help.
  5. I’ve been finding and opening Mazon creek fossils for years. I have never seen one like this. Any ideas? It’s a black shines and it goes top to bottom Thanks

    Cartilage pieces in nodule

    I found this half of a nodule in Catoosa Oklahoma. I didn't realize what it was at the time or I could have searched for the other half. I have found bone and cartilage pieces at this site before but not multiple pieces in the same nodule. There are at least 6-7 pieces. It is Pennsylvanian from the Oolagah Formation.
  7. It's been a while since my last post on here as I don't get out as much now and when I do is only locally for a short time. These 2 finds are from the spoil of a long closed pit in the Derbyshire Coal Measures UK. Asterophyllites shoots. Calamostachys A lot of digging for two small finds but I enjoyed the hunt ! Cheers John
  8. I will be working in western Washington this summer and I was hoping to squeeze in a day of fossil or fossil nodule collecting. I am looking for recommendations for one day of recreational fossil hunting.

    Unknown nodules

    I found a large area with a layer of nodules and broke open a couple hundred. I know what the denticles are and I think the teeth are campodus but everything else is unknown. Any id's are appreciated thanks

    What are these, eggs?

    I found these while digging in red clay on the banks of the crooked creek that runs primarily through bollinger county. In the same location that I have been finding many smithville snail fossils. They are egg shaped and fairly brittle. All were in the same spot in the clay. Can anyone help me identify them. Are they fossils, if so what?

    Nodules in Redwall Limestone, Central AZ

    The photo shows several nodules embedded in Redwall Limestone (Mississippian) along highway 89a west of Jerome, Arizona. Also in this layer are crinoids, brachiopods and solitary rugose corals. I think I've read about these in the dim, dusty past, and I seem to recall that they are not fossils, but some other geological phenomenon. Any help?
  12. I recently found several fossil plant impressions inside nodules from Indiana coal mine spoil dumps. It is Pennsylvanian age approximately 300 mya. Please help identify the specimens to genus, and species if possible. Thanks!

  15. These are my favourite egg cases that i have collected from the coal measures of Derbyshire UK. The largest is 120mm long. Thank-you for looking John
  16. These are some of my favourite Horseshoe crabs i have collected from the two opencasts in Derbyshire UK.that i have hunted in over the years. (some are in negative form) they range in size from 10mm to 40mm. Thank- you for looking at many years and hours of collecting. John

    Mazonia (Blob) fossils, please help ID

    I actually went to Mazon creek for once, however I’m quite new there so I need some help identifying what I found

    Greenland Fish Nodules

    Just got in some nodules from Greenland courtesy of our good friend @holdinghistory. Never dealt with these before. Do I freeze/thaw these? What would be the best course of action for opening these little fishies up?

    Pit spoil

    Went looking on a old pit spoil that is slowly giving up it's nodules,the site is in the British coal measures of Derbyshire as with Mazon Creek it is well overgrown but the nodules here are not easy to find ....Yet! These are 2 nodules from the spoil that i'm sure will one day give up it's treasures. Asterophyllites sp Lycopsids Cheers John
  20. I just went to the Floyd county Conasauga at a roadside site mentioned in https://www.researchgate.net/publication/264495630_Taxonomy_and_biostratigraphic_significance_of_some_Middle_Cambrian_Trilobites_from_the_Conasauga_Formation_in_western_Georgia (partly guided by a few locals). After searching, we found tons of nodules, and only a few exposed Trilo parts. It was only near the end of the trip that I realized that at this site, I might need to split the nodules open to find much in them. So I took a few decent sized ones with me to figure out what to do with them after I attempted to split a few, and only getting one open relaitively cleanly (nothing inside). My immediate assumption is perhaps to use the freeze/thaw method I've heard people use for mazon creek nodules (instructions?). Any other tips for splitting these nodules? They're much tougher that I personally thought they'd be (at least it was harder to actively split them on site, given their round shape makes it hard to keep the chisel going in one spot). The site: Some of the numerous nodules present:

    Mazon Creek area nodules

    Hi everyone! Today I have something different to show you all: Mazon Creek area nodules that have opened for me via the freeze-thaw method!!! These unopened nodules were acquired from @deutscheben after I asked him if he wouldn't mind sending me some since I wanted to try my luck at opening them myself. He generously sent me 18 unopened nodules, all of which have gone through the freeze-thaw cycle I don't know how many times and so far only 3 have opened up. I'd like a little help in identifying what they are - thanks in advance!!! I believe they are from the Pennsylvanian period of the Carboniferous - any and all help/suggestions are appreciated!!! Monica Nodule #1, both pieces: I believe this is an Annularia sp.: Nodule #2, both pieces: Perhaps bark or Cordaites sp.? By the way - do you think I should put the bigger piece back through freeze-thaw to see if it opened up some more? More to come...
  22. Herein I plan to post pics of my modest collection of Mazon Creek fossils, but first a question. I found this nice little map in a paper by LoBue (2010) of the general Mazon Creek area, showing the location of the numbered mines/pits. Could any of you who know the area and the fossils explain in a nutshell which areas produce the Essex Fauna and which produce the Braidwood Fauna (or flora - maybe I should say 'Biota')? I know Pit 11 is the main source of Essex fauna (Essexella etc.), but is it the only place Essex fauna occur, and those other pits produce only Braidwood biota? Are they relatively exclusive of one another or is there some crossover? I work best with maps, so if anyone can annotate the map to make things clearer, please do. Also I'd like to know where the county lines are on this map. In the following fossil pics, I have incomplete info as they all came from dealers, auctions and such, I've never been able to collect the site myself, so the info I receive is typically incomplete and sometimes wrong. If anyone could narrow down any of the location info for any of the fossils, I'd appreciate it, and please correct anything that is incorrect!
  23. On my holiday trip from Ohio back to Minnesota, I thought of taking some time and searching the Braidwood area for fossils. I overnighted in the area, jumped out of bed at the crack of dawn with anticipation and headed to the Mazonia-Braidwood State Fish and Wildlife Area. Unfortunately, the park was gated off and access was only allowed for hunting (animal) purposes. On top of this, light snow began to fall making it hard to see anything on the ground. I did manage to look under some trees outside of the gated area and found what looked like a few nodules. It is common knowledge to open these up with a freeze thaw technique, but my hammer kept calling. So after a few whacks, this is what I saw inside. Can anyone identify anything in these pictures?? I have extreme difficulty seeing what many do when looking at open nodules. So an expert eye is needed. Mike

    Small Pinnules

    In a previous post i showed some finds from the British Coal Measures of Derbyshire , this is a small nodule from there it measures 21mm long x 12mm wide and the longest pinnule is just 4mm . I have tried to show it's size in these 4 pictures. and just so you don't get bored looking at the same fossil here is a.... Asterophyllites Equisetiformis Cheers John
