  1. I had contacted someone to register myself regarding a private hunt in a creek. They serve a picnic afterwards. I was to receive verification a month ago and none has come. Does anyone know how to contact the couple offering this? I have lost their information. Mike
  2. Over the past year, I've become fascinated with the often bizarre fish and sharks of the Pennsylvanian. Fortunately, my home state of Illinois is a great place to hunt for such fossils. I've shared several of these in other posts before, but wanted to put everything together in one thread. Probably won't have much to post for a few months after this, but once summer rolls around, I should hopefully have plenty of new finds to share. I would say there are three major settings in which you can find fish fossils in Illinois: Mazon Creek, black shales, and limestone. I have not had luc
  3. Last summer I posted a trip report about finding some Pennsylvanian black shale in a river bed in East Central Illinois http://www.thefossilforum.com/index.php?/topic/106753-628-illinois-black-shale-trip-w-listracanthus/. I was able to visit the site again once more in the fall last year when the river was running much lower and collect more and larger pieces of the finely bedded and fissile shale. Since then I have been slowly splitting and going through the rocks I brought home, and finding many interesting fish parts- that is definitely the dominant fauna presen
  4. Hello everyone! I've been inspired by so many good Mazon Creek topics in this forum, I thought I would start my own. I'll post my own finds, which so far don't include anything as exotic as a Tully Monster, but maybe I'll get lucky on page 134 or so... I have to credit my kids with getting me interested in fossil collecting. I was always interested in rocks and fossils but when my 10 year old son had his dinosaur phase it really sparked my interest again. I wondered if an ordinary person like me could go out and find fossils? So I Googled fossil collecting and found out that not on

    Mazon Creek Collection

    I'll update this thread with my Mazon Collection over the next few weeks. With some good weather out yesterday, I managed to get my first fossil hunt in for the season and will post a report in this topic. I will be moving this upcoming summer which will put me even further from Mazon Creek so I have purchased a few pieces to fill in the genus/species I haven't found yet and will mention if I purchased a fossil. I still hold out hope to find some of these pieces I purchased eventually but will realistically be difficult if I only can make 1 trip a year. Fauna Tullimo
  6. With the nicer weather last week, I was able to make two brief trips to kick of the year. There still ended up being a lot of snow on the ground, but it was manageable. My first trip was to one of my favorite sites, a roadcut in the Pennsylvanian LaSalle Limestone in Illinois. Lots of the usual stuff was found, but the two trip makers were a small Peripristis shark tooth and a Linoproductus mass mortality plate. Here's the tooth. I think it will clean up nicely. And here are the Linoproductus. There's around 50 individuals present, and they are all quite small com
  7. Hi! My son (10) has been very interested in Mazon Creek fossils for years, and has been asking to go down and try to hunt for fossils there. He’s quite serious, knows a lot about Mazon Creek for a kid, and has experience with both all-day hiking and moderately successful fossil-hunting. Is there any chance that someone does (or would do) a guided trip there? I would feel so much better trying the trip if we had more expert help. I know he can handle a long day in the sun hunting - but I honestly don’t have the skill to be 100% sure of what I’m doing, and I certainly don’t know exactly where to

    Mazon Creek Jellyfish?

    Location: Mazon Creek (Illinois) I think some or all of these may be jellyfish, but I'd like to defer to others. If they are not jellyfish, what are they? The last two photos are both sides of the same pieces. There appears to be something on both sides. Thank you for your time.
  9. Current forecast is perfect – rain all weekend but sunny and clear on Monday. Fingers crossed it stays that way! Hope to see some of you out there.
  10. For the last 4 years I have been collecting plant fossils from sites in East Central Illinois. These fossils were all brought to the surface by underground coal mining in the first half of the 20th century. Most of the spoil piles in the area have been graded or flattened out, but a few still remain, standing tall above the flatland. One particular pile is, I believe, the source of most or all of the fossils I find. The shale that makes up the spoil has been fired by the internal heat of the pile, resulting in the hard, reddish material known as "red dog". This shale i
  11. Another find in Pit 11 of Mazonia-Braidwood complex. Found already open on the ground. I was unable to find the other half. It looks a bit like the images of Neuropteris fimbriata and Cyclopteris trichomanoides in Jack Wittry's "The Mazon Creek Fossil Flora."

    Mazonia-Braidwood Vertebrae

    Pretty sure these are amphibian vertebrae. Found in Pit 11 in the Mazonia-Braidwood complex.

    ID help, Maclurites?

    Hi All, Wondering if I can get some ID help with this, after reviewing various sources I am thinking Maclurites? Location: Belvedere Quarry (ESCONI trip 2020) Dolomite, Galena formation Thank you!
  14. Today I was looking at fossils that I have paid any real attention too in quite a while. I figured that I would try and organize some of them and I started moving containers and pulling out concretions that contained coprolites. The pieces that I was working with were larger pieces, and that is what this post will show. I have found coprolites in the Essex (Marine) and Braidwood (Fresh) biotas. Many collectors in the past would skip over coprolites, just like they did with Essexella asherea Jellyfish, but that is not me, I would pick them all up. Mazon Creek coprolites have been known to conta

    Southern Illinois Shell

    Hi All, I've been spending some time with family in Southern Illinois, in Madison County. In between eating too much for the holidays I've been exploring around the farm and the creeks for arrowheads and anything else I can find...while exploring one creek bed near some rather large cliffs I found what I am guessing is a fossilized shell, some kind of sea snail/whelk/conch. I don't know if this was an unwanted hermit crab someone tossed away, or a part of a shell garden that made it's way in there, or a legitimate fossilized shell. Any help would be apprecia

    Black Shale from Illinois

    This was collected at a private recreation club west of Pit 11 from old spoil hills. I have found Listracanthus spines from this type of black shale. I’m not sure if this is a large spine or something else. Thanks

    Fossil or Odd Rock?

    Like in the title, I am unsure if this is even a fossil.
  18. I graduated college back in May, and since my graduate program did not start until September, I was fortunate to have quite a bit of time this summer to explore further away from home. I've been slowly prepping and cataloging over the past couple months, and figured I would share some of my favorite finds that I haven't shared yet. First up is dump piles of Silica Shale (Middle Devonian) in Paulding, OH. My university was not far from here, so this is really where I started fossil hunting. I've been here quite a few times, so most of what I found I already had in

    Trilobite ID request

    Good morning folks. I have just received a Trilobite from the Silurian Period of Kankakee, Illinois. It has not been identified by the seller and I'm wondering if someone here might know what species this is.

    Think its a bone

    Hi, thanks in advance. Found near st Louis in illinois. It seems to have hematite or iron coating. I also collect bones and that sure looks like a fossilized bone. Really lightweight.

    Pit 11 Poychaete Identification Help

    Hi all, this is one of the polychaete worms from the batch of Pit 11 concretions I'm working on. From what I can see of the conical jaws it most closely resembles Didontogaster corydylina but the jaws blend a bit together and aren't as distinct as some other specimens I've found. The body profile seems a little off (no swollen front section for one) so I wanted to ask for second opinions. Am I getting too hung up on the profile of a body that could just be more outstretched? I appreciate everyone's thoughts.

    Pennsylvanian Bivalve (Bond Formation)

    This bivalve came from an outcrop of the Bond Formation in Edgar County Illinois. Edit: After further research it seems to resemble something in the family Sanguinolitidae but without better references that is likely as far as I will get with it. Hopefully someone will have another idea or more experience with this strata and area.
  23. I collected this little worn cephalopod in a stream in Peoria County Illinois. The area is primarily Patoka-Shelburn Formation Undivided (Pennsylvanian) but it wasn't found in-situ. I sectioned a piece for identification and the siphuncle seems large for the Pennsylvanian cephalopods known from the area. To my eyes it looks a lot like Actinoceras (which I guess would mean Ordovician) based on the position and size of the siphuncle. Does anyone have any other ideas?

    Devonian of Illinois Identification Help

    This beautiful specimen came from the Clear Creek Formation (Devonian) of Illinois in Union County. Does anybody have any ideas for identification?
  25. Hi everyone, These unidentified specimens were collected in Union County, Illinois. It's from Mississippian strata, likely the Ste. Genevieve Limestone or St. Louis Limestone. I haven't been able to track down a proper map of this quadrangle yet. The smaller specimens resemble mound bryozoa like Prasopora and the cups of all of them display concentric layers like related bryozoans. There aren't any pores visible so I've been thinking about bisecting one of the smaller specimens to see if any radiating zooecia are visible. What does everyone else think? Does
