Hey everybody! Welcome to my Mazon Creek thread, where I’ll be posting pictures of various Mazon Creek finds! I’ve been hunting there for upwards of 10 years, so I have piles of uncracked nodules just waiting to be opened. So as they open, they’ll find their way here! Feel free to jump in and add your own and keep this thread going! And I’m sure there are many that have gone unidentified, so I’ll probably need some help from the experts!

Hey everyone, I took my first trip down to collect the famous Mazon Creek concretions over the weekend, and this is one of my first concretions to open so far. I was hoping I could ask for some clarification in what I'm seeing. My first thought was just that it's a clay deposit, because the lighter material which the crack is running through seems to be clay or another substance which is very soft and crumbly. Additionally, there are what appear to be much darker needle-like inclusions of material running randomly through that more crumbly material, which unfortunately I do not know how to photograph. On that note, my apologies for the awful cellphone photographs. I hope they're clear enough for a rough identification. The grayer material on the left is much harder, and appears to be crystalline. I was guessing possibly a shell? (replaced by quartz? does that occur at Mazon?) The white deposits (calcite?) at extreme left seem to be a separate feature from the U-shaped feature stretching across most of the concretion. Thanks so much for your time. I'll try to scrounge up an actual camera soon.

Hi all, I have been having some trouble with this specimen. It came from a large collection of Mazon pieces I purchased a number of years back from collector Ron Brandt of Normal, Illinois, who self-collected and also purchased several extensive collections from others. Originally it was identified by someone (too far in the past) as an egg sac of some sort, but after some discussion with someone I would consider an expert, a fellow named Dan Damrow, who some of you may know, some doubt has been cast on that identification. I would be interested in any comments or insights you may have. Thanks, Paul

Hi all, Can someone tell me whether I'm looking at a shrimp that was in the process of molting? Thanks! ~Paul

Can anyone tell me whether this seller has these IDs right? I figured the first one looks like an Achistrum (sea cucumber) to me. The seller has others that I have questions about too but won't post them all. @RCFossils ?

I collected some small nodules last week and when I tried to open this one the top split to reveal this. I decided to hit the larger part one more time to see if I could uncover the rest. Instead the larger piece split in half and this is what was inside the same nodule. Are these annularia? They are very different from the other fossil I found in the right picture which I am pretty sure is annularia.

I FINALLY got something recognizable that didn't flake or crumble and now I don't know what it is. It was collected near Monster Lake in Braidwood. According to my identification book it may be a Cyperite, however, the book also says that these are "uncommon in most areas."

I am new to the fossil collecting hobby and am attempting to open my iron concretions collected in Braidwood, IL using the freeze thaw method. I am doing it in my freezer in a single layer in a plastic shoe box. When they are thawing at room temperature the outer layers are crumbling. The nodes have not split yet. Is that normal or am I doing something wrong? Thanks.

Went out this afternoon hunting for Mazon Creek fossils in Mazonia-Braidwood. We spent about three hours searching for concretions without a lot of luck. We did find a couple of small ones. I wanted to check out one more area before we left and we ended up finding the attached. It is the largest one I have ever seen (in person or on the internet). It is hard to tell, but that is a quarter on it. When I went to pick it up, the nodule on top detached from the lower half. That nodule is probably the largest one I have ever collected. It is clear by looking at it that it used to be one large piece. My question to the group is, has anyone found anything this large? Should I try to open it myself (freeze/thaw) or try to find someone more experienced?

Going through my collection, I've come back across some pieces that I am unsure of, some of them may not even be fossils, others I have an idea about but I'd like to hear the community's thoughts. 1 coprolite, plant, mineralization? 2 shrimp antennae or legs? 3 4 5 6 trace fossil or "H" 7 8 partial scallop? 9 coprolite, mineralization, worm? 10 11 I'm 95% sure it's plant but I want to make sure it's not tooth

My drawing of a little blue blooded fossil from Mazon Creek
fossilcrazy posted a topic in Paleo Re-creations
This is a drawing I made a couple weeks ago. It is Euproops danae, a Pennsylvanian Horseshoe crab from the Mazon Creek (proper). My nodule is 100% complete with no restorations. Being a Mazon specimen, it comes from the Francis Energy Shale and is about 300 million years old. This drawing was done on textured paper with 2B and 4B pencils.- 9 replies

Hi there had a successful outing at Mazon Creek today! Came back home with a 5 gallon bucket full of nodules. Made it a long walk back to the car though! Was hoping to get some insight on some of the preopened nodules and the ones that crack open in the future. 1.) 2.) Sorry if pictures are poor quality, I tried my best. Please let me know if better ones are needed .

Hi, I am not a fossil hunter but accidentally discovered the ability to find 300,000,000 yr old fossils in Mazon Creek on a TV show. Wow!!! I've been researching all day and now want to take my family there for spring break in March! Our story (short) & my questions: My daughter is very interested in science and nature and critters. She spends hours outside digging contently for rocks, loves bugs, has rock collections, books on rocks & minerals, etc. She struggles in the classroom (3rd grade) and learns best by hands on experience. She would absolutely be in heaven here- our whole family would! I love to help my daughter experience her interests through our adventures. What advice could you give a family of 3 who has never hunted fossils? We are in Missouri so interested in camping close by- does anyone know of any good evening Camping places? Do we need to register with the state park and get daily admission? Should we go where most tourists go or off the beaten path? Is it possible for newbies to find a few fossils? Even if we found the most common we'd be so excited! We love exploring and take small hikes as a family. Are there spots within a couple miles of the "road" or parking? I truly appreciate any help! I will keep researching as well. I hope we can go and see this unbelievable history!!

I've had a few specimens in my collection that I have questions about and am seeking some clarification. #1 another view #2 #3

Sorry, I forgot about this one. If I post another within two weeks, I promise to distribute my entire Mazon collection among you all. Offer void in the United States and other countries. I think I know what this is, as I see a similar image of one in an RCFossils album. But just to double check, this is what I believe it to be: Mamayocaris Jaskowskii.

To all of those who have made suggestions, educated guesses, and definitive identifications: This is the last one I currently have a question on, and I want you all to know that I have appreciated all of your efforts in helping me to understand and identify some of my more problematic specimens. I have learned a lot from the information on The Fossil Forum, the galleries, and from comments and links provided by everyone. Most of all, I have learned that I know very little, and that makes me appreciate your knowledge even more. Thank you so very much! ~Paul

Are these leaves or wood, or nothing at all?

The first and last ever discovered baby bottlenose dolphin to be found at Mazon Creek! How lucky am I? Not a clue.

Really don't have much of a clue, but think I'm seeing a tail fin at the very least.
-
What I first thought to be a Cyclus, after photographing with shadows, looks kind of like a jellyfish (Reticulomedusa?).
-
One that I initially thought was a coprolite, after photographing and zooming in, I believe I'm seeing a large group of tiny snails.
-
I always thought this was the digestive tract of a worm, but after taking the pictures, I'm fairly convinced that it's a shrimp of some sort.

I think I see body structures here, but I'm at a loss.
