  1. I've been to a least a few museums where they would have a part of an exhibit dedicated to the Carboniferous era (of which the Field Museum's section for that in the Evolving Planet is pretty good). But I do wonder what would it be like if a whole A grade small to medium sized museum opened dedicated solely to the fossils found in the Mazon Creek area, including the Essex Fauna. It could be located close to the Mazonia-Braidwood State Fish and Wildlife area and include life sized reconstructions of both the terrestrial and aquatic environments. It could also be a place where fossil hunters cou

    NE Oklahoma Fossil Deposits

    Hey everyone, I've been trying to plan a little trip for me and my family to go on a little fossil hunt. I live in Bartlesville Oklahoma and I have several nice places I can go to find fossils all over. Mainly mississippian and Pennsylvanian. I'm looking for areas within an hour or so drive from where I live. I'm aware of the pliestocene finds in the arkansas river in tulsa area. I'd love for someone to send me maps or geologic surveys showing what areas in the topography, and other recomendations. Places I've been to worth noting: Kaw Lake spillway, Ponca City (good shells everyw
  3. I've visited the Pennsylvanian Bond formation in Oglesby Illinois a few times but have only found a few cladodont teeth so far! I find a decent bit of teeth from crusher plate chondrichyans like Deltodus, but I've also heard there have been some large cladodont teeth found in the area. I'm just curious what is the largest cladodont teeth found in Oglesby Illinois?
  4. During my trip to a Bond Formation Rock formation in Oglesby, Illinois on October 8th, 2022, one of the limestone blocks I found had a small reddish fossil sticking out on the side of the rock. It was about 2mm in length so pretty small. I thought it was interesting so I brought it back with the rest of the fossils collected that day. There was not a lot of room in my garage for the block so I put it outside on a supply bin for a while. The next couple of days, It rained ALOT. One day I remembered that the calcite in limestone dissolves in rain, so I went out that night to check on what could

    Ameura missourienisis

    From the album: Missouri Trilobites

    One of the smaller specimines, but that just makes for better details! Found this little guy in what I call the upper Winterset Limestone member from the Dennis Formation. This pygidium less than 5mm.
  6. I recall not too long ago there was a pretty interesting scientific article published in the Journal Science describing how scientists analyzed the amount and diversity of chondrichthyan denticles in ichthyoliths from the North and South Pacific dating from around 20-19 million years ago and discovered a sharp drop in the number and diversity of denticles around 19 million years ago, indicating a massive extinction took place which took sharks 2 to 5 million years to somewhat recover from (it's still unknown if this impacted chondrichthyans worldwide or just in the pacific). Here's the paper:
  7. Starting in early 2021, I've been going fossil hunting at the Mazon Creek area in Grundy County, Illinois. The site I visit the most so far is the fairly large Mazonia-Braidwood State Fish and Wildlife Area. After advice from other members of the Fossilfourm, I've decided to put the nodules I'm most curious about under the microscope and dissecting scope! With these better photographs, I'm wondering if anyone could give a proper ID for these specimens?
  8. Starting in 2021, I've been going fossil hunting around the Mazon Creek area in Grundy County, Illinois. The site I visit the most so far is the fairly large Mazonia-Braidwood State Fish and Wildlife Area and at first, I would barley find anything. Then after visiting Monster Lake and another secret location in the area, I started finding more fossils. However, most are around 2-7 cm. In length and I'm still having difficulty getting IDs for them? Would anyone be able to help ID them? I think this could be some sort of Chondrichthyan or a lobe finned fish?
  9. This is the second part of my post describing my recent fossil hunting trip with @Tales From the Shale in Utica, of which it was awesome!!! So after visiting the abandoned clay pit, we decided to go to another location in Utica one might not expect to be productive - the former peabody coal company Pit 15 (or at least its outskirts), located not to far away from Lake Shannon, Kankakee County, Illinois (I'm am not going to tell the specific route or address so the area doesn't end up being picked clean). We went there as I had heard a report that a while ago, someone found a sizable
  10. On Saturday, I went on a fossil hunting trip with @Tales From the Shale in the area of Utica, LaSalle County, Illinois. After some time driving and looking for roadcuts, we discovered an abandoned clay bed/outcrop not too far away from the town itself. There, we discovered an absolutely massive amount of shark spines and teeth! I would like to know if anyone could properly ID some of the specimens we found!! \ This is one of the best shark spines I found at the site!!! It does look somewhat like the spine of Listracanthus, but I'm not 100% sure
  11. I've been recently trying to find some good places to go fossil hunting in the Mazon Creek area and there is one area some say is good but I've never heard or or been to before. It's called the Essex Quadrangle or Essex Quad in Kankakee County Illinois. It's supposed to be extremely close to the old Peabody coal company pit 15 and have fossils from the Essex Biota dating to around the Pennsylvanian period. https://isgs.illinois.edu/maps-data-pub/quads/e/essex.shtml https://ilmineswiki.web.illinois.edu/index.php/0359 I'm wondering if anyone's heard of
  12. Saturday, October 15th, 2022 was the ESCONI Mazon Creek Open House. It was a great day with about 100 visitors to enjoy a event devoted to Mazon Creek fossils. There were numerous forum members in attendance.@connorp @bigred97 @flipper559 @fiddlehead @RCFossils @Roby @Hurtlady @jdp to name a few. For a full report with videos of 3 of the 4 presentations, please visit the ESCONI website. The fourth video will be posted after the research is published. Recently, we've had a few historical posts about the Mazon Creek Open House events in the past, Mazon Monday #133 and Throwba
  13. I've been looking at the records of the Carboniferous Eugenodontid Chondrichthyan Edestus in Illinois (famously referred to as the coal shark) in Illinois and I've found that there are a large amounts of reports from Underground mines at Sparta and Coulterville, Randolph County Illinois. I also found a record from fossilworks.org simply listed as "Coal mines of western illinois" at the coordinates 38.7° N, 90.0° W. http://www.fossilworks.org/cgi-bin/bridge.pl?a=collectionSearch&taxon_no=34453&max_interval=Carboniferous&country=United States&state=Illinois&am
  14. I've been looking recently into possibly fossil hunting by Alton, Illinois for specimens of Mississippian era fauna. I'm specifically looking for general places like roadcuts and quarries with 330-340 million year old St. Louis Limestone (Meramec group) in the Alton area. I'm just wondering (without anyone being too specific about localities) is there any general places like quarries or roadcuts that match that description in Alton, Illinois?

    Trip to Oglesby 10/08/2022

    A few days ago, I went with @Tales From the Shale and another friend on a fossil hunting trip to a Bond Formation Roadcut in Oglesby, Illinois with rocks dating around 307-303 Million years ago, to the Pennsylvanian section of the Carboniferous era. We worked for at least 5 to 6 hours, but it was worth it! This was one of the best fossil hauls I've had in a long time at that location! The true gem of that trip was this Cladodont tooth I discovered by sheer accident!!! The specimen may come from the Shark Gilkmanius, but I'm not too sure?

    Bond Formation Cladodont species ID

    Recently I went on a fossil hunting trip with a few friends to a roadcut in Oglesby Illinois from the Pennsylvanian Bond Formation. This was around July and I found a lot of cool Brachiopod fossils, but I decided a few days ago I wanted to get a closer look at some of the larger matrixes I collected to see if I missed something! At the very edge of one the matrixes, I discovered a small pretty exposed cladodont tooth that I couldn't find a specific ID of? The specimen is about 1/2 inch in length (5.0 mm.). But I wanted to see it a bit closer, so I put it under a microscope on

    Saivodus in Illinois?

    I have recently been combing through the geologic records of the Carboniferous Ctecanthiform shark Saivodus striatus and I'v found something curious. It's been found in Mississippian deposits in Indiana, Kentucky, but not really Illinois! https://www.uky.edu/KGS/fossils/fossil-of-the-month_2022-07_Saivodus.php I've heard that Cladodus ferox and C. spinosus (considered synonyms of Saviodus striatus) have been found in the Carbondale and St.Louis Formations in Kankakee and Madison county respectively, but I'm wondering if this is correct? I'm wondering if any

    Oglesby Fossil ID Part 2

    I've visited Oglesby Illinois a couple of times to collect fossils from the road outcrops with Pennsyvanian era fossils - which so far is one of the best fossil locations I've been to so far besides Mazon Creek! On one of these trips, I found what I believe to be extremely Chondricthyan teeth with each only around 1-2 mm. Would anyone be able to give an ID for these specimens?
  19. Muffinsaurus

    Is this coral or sponge?

    My neice just pulled this out of the creek at my mom's near Ashland Kentucky. I know the area to be Carboniferous. I think it's a coral, but I'm still too much of an amateur to know for sure. Any help would be appreciated by myself and my neice.

    Mystery Danville Trace Fossil

    Hi all. I found some pretty cool boulders of calcite littered with crinoid impressions in a public park in Danville, IL back in late August, but left everything until I got approval from their park department to remove them. I finally heard back last month, but didn't get around to going until today. I found a few interesting things that I'll post when they're cleaned up, but I probably won't even begin the process until Thursday. In the meantime I took a photo of a trace fossil that was sitting near the top of one of the specimens. I can identify most of the things in the pieces, but am
  23. hello! I went fossil hunting a few hours ago and while doing so I came across a phosphatic nodule that was naturally opened most likely due to freeze thawing Formation: Muncie Creek Shale nevertheless I was wondering if someone could confirm if this is a Campodus sp. tooth as I am assuming it is since it resembles my other Campodus teeth and also wanted to see if anyone can help me remove the the mud from this tooth without damaging the fossil inside by giving advice/Tips I do not have any prep tools Without further delay h

    Unknown Mazon Creek Fossil

    A specimen from the 1970's or 1980's, but unfortunately date and specific locality are lost to the ravages of mind.... I would appreciate any help in un-Insertae sedising this one! The light blue grid is one inch.
  25. Howdy all! A few more odd finds from the Bridgeport Pennsylvanian matrix. I could use your help! 1. Size 1/4 inch The first one looks maybe like one of the sponge Girtycoelia surrounded by ...something. A bryzoan perhaps? It does not look like any bryzoan i know, but i know very little about the Pennsylvanian (although I did get the Color Guide on CD! yay!) Close up 2. This thing: Size 1/16th inch. I thought it was a seedpod originally (which in my previous posts....yeah, those were indeed seed pods...finally crushed on of them). I tried to
