  1. 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
  2. Hi again. So after reading around here and different places I think that these are nodules with some bits sticking out of them? I have had a little go prepping a couple to reveal what's inside as you will see in the photos. I just want to know am I wasting my time doing this? It quite hard to identify what's inside with just random pieces sticking out... Thanks again for any replies it really helps me work things out with all your responses. Oh and getting all these back to the car almost killed me :x
  3. 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?
  4. 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
  5. 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:
  6. 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...
  7. 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
  8. 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
  9. Pit spoil finds

    Some spoil finds from a few outings into the British Coal measures of Derbyshire. Sphenophyllum Emarginatum Mariopteris more finds too follow.........
  10. What are these things?

    A friend of mine(yes, it really is a friend, not just me lol)apparently got these in a box of stuff, and they were labeled as being from mosasaurs. He asked if they were coprolites, but i don't know exactly how they were described. I told him no, I don't think any coprolites would be so smooth, even, and without any imperfections(I'm sure there are some like that out there, but that must be pretty rare. A random group of coprolites aren't going to all be like that, I'd imagine). I told him I don't really know and that id ask, but my best guess would be either gastroliths, or nodules. I don't think mosasaurs have gastroliths, but plesiosaurs do, and the ID of mosasaur seems bunk anyway, no matter what they are. As far as nodules, I don't know if nodules are found in that kind of site, so yeah......does anyone have any idea? Oh yeah, they're from Khouribga, Morocco.
  11. 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!
  12. Marine fossil ID

    Well, here’s another that we found today on the James River in Virginia. It’s 2.5 inches. At least I know this one isn’t asphalt!
  13. I dont know if this is the appropriate place to ask but I thought I would go to the source to ask. Looking for people that have some crab from NZ that they wouldn't mind working a deal. trade or sell. PM me if you or someone you know can help. It's one of the fossils I'm looking to add to the collection and since I love to prep it should be a win win.
  14. Mazon Creek Nodules

    I recently bought a few collections/accumulations of Mazon Creek fossils. One of them seems to have been a collection of all fauna. After sorting out all the pecopteris ferns and such, I am left with a pile of what seems to be mostly fauna. I am not very familiar with them and don't have very much time right now to figure out the classifications. So I thought maybe someone here would like to work out some sort of trade in exchange for ID'ing these nodules for me? There are shrimp, worms, maybe a few more unusual plants, and stuff I have no idea on. I think I have about 50 nodules. PM me if you are interested, thanks!
  15. Pennsylvanian Nodules

    We went up to Terre Haute, IN for a wedding this past weekend. I was looking forward to us being able to actually hunt for some fossils of our own as I had read online about Fowler Park/Griffin Bike Park and its nodules. I decided to check out the park rules after we got up there and lo and behold, Vigo County doesn't allow fossil collecting. I didn't want to set a bad example for my daughter so we refrained, much to our dismay. On the way home we stopped at an antique mall and happened to find someone selling jars of split nodules! So, we didn't come home empty-handed after all. Below are the better pieces that were in our jar. I used this guide and decided we had some pecopteris and macroneuropteris, but I'm not sure what all of them are, especially the blobby thing on the upper right. See detail photos of blob.
  16. Are these IDs correct?

    I just got all these fossils in bulk and was wondering if these IDs are correct. Sorry for the long post. The IDs came mixed up so please correct me if you see any that are wrong. All collected in Yorkshire. Hildoceras Bifrons with shell structure showing? Hildoceras Bifrons on a small nodule Hildoceras Bifrons with some pyrite. Arnioceras Block Catacoeloceras Grammoceras Large Repaired Pseudoloceras Pos and Neg X2 Eleganticeras Androgynoceras Boneblock with Ichthyosaur ribs and verts on the side.
  17. Mazon Creek ID help

    Hey Everyone! Happy new year! A nodule from South Pit 11 Mazonia area split and can't figure out what it is? Millipede? Shrimp tale? I have the Wittrey book I've been looking through and I see similar features on multiple animals from his pictures. Thanks for your help!
  18. Just Geologic or fossils

    I have some nodules I found already opened that have rounded raised or flat curved lines that go against the rest of the directional patterns of the nodule. They seem to be found in oblong or curved shaped nodules. I didn't know if these were actually fossils or just geologic formations. Again, I am afraid to get rid of anything for fear of rejecting an actual fossil in ignorance.
  19. Stains or Fossils?

    After freezing and thawing, I broke open some nodules from Mazonia Lakes that have some interesting patterns inside of them. These are nodules that did not show any signs of opening along any natural cleavage. The first nodule broke in half vertically when the shape (oblong oval) suggested it would open horizontally. The white material seems very thin and reflective, it reminds me of a plastic decal..Any ideas of what they could be?
  20. Mazon Creek locations

    The week of Thanksgiving, my son will be graduating from Navy Basic Training in Great Lakes. My 10 year old son and I will be coming up to see him graduate. On the way home, I'd like to stop off and have a look at Mazon Creek and see if we can't pick up a few fossils. I saw on line that there is a park you can hunt at, but it apparently is only opened during summer months. Does anyone know anywhere that my little one (he's 10, but autistic, so he's not quit up to speed with other 10 year olds yet) and I can have a fairly quick stop to find a few? Also, I've read about the nodules you crack open. Any tips on how to tell a nodule with a fossil from just an ordinary old rock? And are there any other type fossils to look for? Thank you for any tips.
  21. Bumpy Nodules

    Two halves of the same nodule.
  22. Mineral Deposits or Fossils

    I found some already opened nodules that I cleaned up. I wasn't sure if these were fossils or just mineral deposits.
  23. Hi, never posted before so please bare with. Found this fossil in a house clearance (Uk). It's sandy in colour across the surface and an off white (chalky) colour in exposed areas. Have included a tape measure in the pics for length (approx 10 inches). both sides (as shown) are deeply textured and it measures 3.1/4 in depth at its deepest but does taper down. (Hopefully shown in pics). Would really appreciate some help with this. PS each "segment" is divided by a very thin, but clear ridge/seam. Thanks all for your help Any more info required, I will do my best. Many thanks.
  24. Mazon Creek Nodules

    After cleaning off some already opened nodules and freezing a few dozen others I have a few that might be fossils. (I haven't been too good at figuring what is and is not a fossil so I'm not feeling very confident.) The first nodule pictured I cleaned in vinegar and am thinking is a jellyfish? The second I found as is and haven't found anything that looks like it. I checked out The Mazon Creek Fossil Flora by Jack Wittry and Richardson's Guide to the Fossil Fauna of Mazon Creek from the library to help better understand this but I still see a lot of confusing images in my nodules. I don't know if those are the famous jellyfish blobs or just nothing. I have another sample of a nodule I split that may be a fossil, I will attach the photos next. Thanks for your help.
  25. Another Mazon creek batch to ID

    Okay, today I have four more nodules to check. Again, some may be unfossiliferous. I'm expecting a few more jellies, and maybe a rock or two. One might be iron concretion, because of the crocodile skin pattern. Some , may need to be cleaned of calcite, the one from my last post is still being cleaned. If any more pictures are needed just let me know. Thanks and good luck!
