@stats @Mark Kmiecik @RCFossils @Peat Burns @connorp @deutscheben@fiddlehead I had been in contact with a friend (Bob) of mine that I met over 30 years ago. I met him through my fossil mentor Walter. Bob and Walter would collect in the 70’s and 80’s with many well know collectors, including Francis Tully. The would also bring fossils to the Field Museum so Dr. Eugene Richardson and others, could ID some of their finds. In our talks over the last several months, he had spoke about selling his collection and I advised him that I would be interested. We came to an agree

I have a lot of unopened Mazon Creek concretions and though I do put some out in the winter for the Freeze / Thaw process, the vast majority, especially the larger ones do not open. So to dwindle my concretions, I have no problem whacking them with a hammer, and that is what I was doing today. As we all know, this is not the best way to do it since it can damage a nice specimen, but I take my chances. I always picked up any concretion that looked promising and never passed up larger ones. This all depends on the are that you are collecting, concretions from Pit 11 are never super

I’m sorry these photos are probably awful cause my phone quality is awful lol. But I had a few small concretions from mazon creek that opened today and these two im having trouble identifying. 1st reminds me of an egg case but I highly doubt it. It kinda looks like coprolite too. 2nd a bivalve of sorts?

Hey everyone! Haven't posted here in a while, and thought I would come back with a trip report. Recently I became interested in Mazon Creek fossils - something unusual for me as a vertebrate person. I finally managed to get out in the field this spring and visit the Mazonia-Braidwood State Park and the Braceville spoil pile through an ESCONI trip. I have collected at quite a few Paleozoic sites before, but this was my first time hunting in the Carboniferous! I went to Mazonia with a friend on a weekend in early April, when there was no foliage and it was sunny outside.

I've been spending a lot of time lately studying the Mazon Creek flora, and am continuously astonished by the diversity and quality of specimens that can be found. I don't think we see enough plants on the forum, so I figured I would go ahead and share some of my favorite finds. First is a specimen I recently shared, and a fitting start to the thread. This is Crenulopteris acadica, the most common true fern found in the Mazon Creek flora. It has been the most common plant I find, accounting for probably half my finds. Next is a favorite of mine. This is a s

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

As many of you know I recently bought a Mazon Creek collection from my friend of mine that I have known and collected with for the past 30+ years. Along with the fossils was a lot of his paperwork on the fossils- not where they were found, etc., but pictures and times that he loaned specimens to museums. One specimen was a winged insect that he had loaned to a person from Harvard (Museum of Comparative Zoology- MCZ). Bob did not have a picture of the fossil and kind of thought it was a dragonfly. This person had visited the Mazon Creek Open House that was held on October 27th, 1984, at Northea

Last Thursday decided to get out to Pit 11, Mazonia South Unit, Illinois for a day of collecting nodules and fossils. We've had a lot of rain and Thursday was clear. With all the rain, nodules are easier to see when wet as they jump out as a bright red compared to the green forest floor. And the rain hopefully erodes some fresh nods out of the ground. I sometimes go on foot for collecting but thought I would break out the kayak to get to where I need to go more efficiently. The woods are getting quite overgrown already but I haven't been out much th

Mazon fossils donated to the Indiana State Museum

I officially got notice that my Belotelsonid and trace fossil cf. Protovirgularia dichotoma were accepted into collections at the Indiana State Museum! -
Today was Day 2 of ESCONI’s Braceville Shaft Mine Trip. Rich @stats will add some pictures from yesterday’s visit. He advised me that there were several FF members in attendance, including, but not limited @connorp , @bigred97. I believe that there were 50 participants yesterday and I believe that there were that many today. The weather was great for collecting, with the temp hitting a high of 80 by the time I left at 12:30 pm. People arrived a little before 9 am for the welcome talk and information on the site and collecting details.

Hello again. I got the time to scrub off my finds from Friday and found one of interest (and a second that I haphazardly split open that I think is a dud). The top one’s shape remained after several rounds of intense scrubbing, and feels slightly 3D in the middle. Other views of top one: Is there anything in the top one or is it just suggestive mineral staining? Additionally, since there is a crevice present around the entire perimeter, would you recommend I try and pry it open or leave the concretion as is? Lastly, just so I can docu

Hello. I’m currently at Mazon and after about 1 1/2 hours of intermittent hiking and searching, I found a hillside that seems to be rife with concretions. I’m somehow lucky enough to have a tiny bit of cell service. I am concerned, however, that I have stumbled upon someone’s discard pile rather than a concretion gold mine. Most of the 100+ concretions were found either on the surface or very slightly embedded in the soil within a 30 foot radius, and most have jagged edges and are only half a concretion. A couple have even been larger than my hand. As such, I know it i

Hello! A couple weeks ago my family and I drove to Mazon Creek and found our first nodules. I was keeping my eye out for the tell-tale round layered shale, and picking up already split ones too. I also saw a similar thread posted recently, just want to confirm if these are indeed duds or not! Most of the finds are about 3cm #1, The most intriguing one to me #2 #3, all of them together to show frequency and variety of circle pattern Thank you very much for reading!

Hello, I opened/cleaned off some nodules I had collected recently and I am unsure if they are fossils or just formations of how the rock separated. Thank you in advance for your time. Also, if anyone has any recommendations on fossil books, that would be appreciated. 1) I am not sure if my eyes are lying to me or not but I see what could be a shrimp. I see the formation of a shrimp body. Also what appear to be two eyes and a nose. Again, maybe I am just seeing what I want to see. 2) Not really sure what this could be. I did not think it was anything at first but then I opened a

Hello, While searching for concentrations in Mazon Creek, IL, I discovered you can find Crinoid stems in rocks around the area. I have found a few of those but recently I found a couple that are similar but not as easily identifiable. Below are the two samples in question. Thank you for your time and assistance with the IDing. 1) This sample is very similar to the type of rock I find the Crinoid stems in. Seems to be like fossilized coral with the holes. Specifically, I am looking at the spiral with a bump in the center. I think that is an impression of a Crinoid stem t

Hello, I am new to the fossil finding hobby. I have been finding nodules with no discernible fossil but are different than others. If anyone could tell me what these are, that would be great. Thanks for your time. These 2 have grey circles in the center. Are these just mineral deposits? This one is similar but it also has crystals in the center, almost like a geode? Then I also find nodules like these that have this strange inner part.

We are slowing finding a few things in our freeze/thaws! Please help ID the six posted below. I am very much a novice on this so my guesses are likely not right, but I tried. 1 & 2: Annularia type? Second pic is how it is also visible from the other plane! It didn't split well, whatever was on top of it crumbled off in the freeze/thaw cycle instead of coming off as a smooth plane so I unfortunately don't have the other half. 3. Probably nothing? I think it's just an unusual fracture, kids are convinced it's more. 4. Coprolite? No clue. 5. Stepanospermum konopeonus?

Hi All! I had the chance to head out last Sunday with my kid and again for a few hours yesterday solo - both times we came back with very heavy backpacks. It’s not easy collecting, but neither of us mind the army crawl in the underbrush. We’re still learning what to take and what to leave - just my 3rd and 4th trip there (thanks to fellow member and friend tom_mo for showing us the ropes and getting me addicted!!) We look for the small water created gully’s in the steep hills, lots of these have been collected over the years but just as many have not it seems. Or maybe the good coll

Earlier this week I had 2 concretions pop open that I weren’t too sure of what they were. Number one has the calcite desiccation cracks that are consistent with Achistrum sp. I guess the shape is what is kind of throwing me off, and the body seems to segmented, which reminded me of a millipede. Number 2 I cant really see any discernible features in it at all but if I had to guess a type of a polychaete worm? Anyway I’m gonna leave this to the experts lol. Any help is appreciated!

Hi all! I have a few questions from the massive amount of new info I’ve learned on here since I started collecting 3/124 at pit 11. I’d went just one time before w my dad back in probably 1982 or so, I have visions of just concretions everywhere, and hammering lots of random rocks, it’s always been a great memory in my mind. It’s been along time, and it’s juuuuust a bit harder to collect now, but I don’t mind the army crawl in the woods, and my 16 year old loves rocks and fossils, she’s having a blast with me. I’m not trying to reinvent the wheel in the freeze/thaw

Hi All! I have a lot of concretions soaking for freeze thaw, but while I wait I have a few of the open ones I found that were pretty covered in mineral deposits, that are now cleaned. I know most are probably not ID-able, but I would love help with some identification if possible! This first one is my favorite - the might be a molt or badly preserved animal but there are some clear abnormalities that I hope can get me an ID or at least narrowed down to some guesses? Mainly the 4 antennae or possibly tails (like in a mayfly) - they are only visible from certain angles, and i

Finally after a streak of bad luck with my concretions I think I’ve found something. First concretion I am almost certain contains something. Looks to me like a worm (?) Second I’m not super confident on but looks different from a lot of the other duds I’ve opened. Wouldn’t have much of an idea of what it could be. Third definitely also looks like something to me, one half did break a bit but I should be able to fix that. I hope the pictures are in order! I will try to fix if not. (I put the penny for scale if that helps)
