Howdy folks. I had a question about soaking mazon creek nodules before starting the freezing process. I’ve had mine soaking in water for 2 days (prior to the first freeze, will be several more days), and there seems to be oil on the surface of the water. Is this normal, or is it something I should be concerned about? This is my first time doing this, and I just want to make sure I’m doing it right. It is just plain water, I’ve added nothing else to it. Thank you!!!

I just had a concretion pop after thawing out today. Lo and behold, it actually has something inside. I’m not really sure what to make of it. Any ID help would be greatly appreciated. It’s about 1.5 x 2 inches. One wet and one dry picture

A nodule from Mazon Creek opened up this week and revealed a nice fossil. I believe it is a Neuropteris Seed Fern Leaf based on pictures examined. The curious thing is the additional leaves that exit the stem. Is this typical or representative of the species???

My bucket of mazon nodules collected this summer have been sitting outside in the sub zero temperatures all winter. I was finally able to fetch the bucket and thaw them out recently. The nodule presented split completely different than other nodules that have opened. This one is a heptagon prism, VERY geometric, not split on a horizontal plane like I am used too . Is there a fossil present on the upper surface and have others experienced nodules opening up geometrical like this one? Thanks for looking Mike Front view Back view.

I was splitting open some Mazon Creek nodules I've had for a while about a half hour ago when this enigma popped out, I have no clue what it is. The nodule is from Pit 11.

Need a little assistance identifying this. THANKS!

This is a half nodule with impressions of several leaves and what I believe is a stem connecting them, from Mazon Creek. Are they Cyclopteris?

Can anyone confirm that this Mazon Creek specimen is of Aphlebia?

Hello fossil hunters! I am asking for some help as a humble beginner. Yesterday I went out with my son (age 14) to a site just south of Braidwood, IL. We were collecting near Ponderosa Lake, to be more precise. This is our second trip out there. The first time we really had no idea what we were looking for, but now we are getting a little more experienced after reading a lot and digging around. In total we found around 60 intact (good shape, in my unprofessional view) concretions, as well as some interesting fragments. We had a nice time collecting yesterday in the cold. We were t

A Mazon Creek nodule popped open a few days ago. At first I thought it was nothing. But in the right light, I have hope (hopefully not false hope) that this may indeed be a find. If this were my Ordovician matrix, I could envision a trilobite. Maybe it mimics a horseshoe crab!!!! During my hunt, I did get to see a horseshoe crab found by @flipper559 I will cross my fingers waiting for the experts to respond.

another unknown tail gate show find. MAZON CREEK, ILLINOIS Concretion half. 7.8 cm

Looking to possibly identify the fossil directly below the 1 inch mark of the measuring tape in the first photo. Any possibly insight would be appreciated. Other fossils on this specimen include coral, bivalves, etc.

First fossil? ever found from hitting rocks with hammer... I’m afraid to try to expose any more of it. Any ideas as to what it could be. First pics with ruler for scale and then without for better detail. I found it along Monster lake in an area where the sides had very recently eroded to expose lots of coal.

Just wanting to confirm that this is a jellyfish.

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

Any chance this is a spider?

Hello- I am hoping to get some help with id for this concretion recently found at braidwood, pit 11. It was found already opened, unfortunately we couldn’t locate the other 1/2 of the fossil. looking at my literature, I am wondering if this is a roach? Thanks for any help with the id of this fossil! -tom

Hello- I am posting for the first time on this site, it's been a great resource for comparing some concretions I've found over the past few years. I've been taking my son on these collecting adventures, and we seem to find at least one nice specimen per trip- although it sometimes take a few months for them to crack open! We found this concretion in Braidwood area, pit 11. It had already split but still together. I have some similar looking shrimp but not 100% sure what this is because the overall form looks a little different, so hoping to get some help

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."

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

Probably not anything that is able to be ID’d but the “eye” spots make me wonder if it is something worthwhile.

I found this half nodule in the southern area of Pit 11 several years ago. I was told by someone at a fossil show it is likely a piece of seaweed. He described it as it being a wavy leaf similar in appearance to a lasagna noodle. Any information about it would be greatly appreciated. Thanks

Pretty sure this is some sort of animal with a notochord but not sure. My fossil friends so far have suggested early amphibian, lamprey, or shark. Given that its from the Francis Shale of Mazon Creek I would think it unlikely to be an amphibian however. I specialize in Neoaves so this is a bit out of my expertise, but I'm pretty sure I've found something amazing!

Next weekend we will be in Marblehead, Ohio visiting my sisters. I had hoped to stop at St Paul, Indiana on the way to look for some fossils. Unfortunately the quarry does not allow visitors at this point due to Covid. My thought then was to consider Mazon. About a month ago, a post was made similar to this one. It was suggested not to visit due to the ticks and other creepy crawlers. Are the critters still a problem??? Does covid close this park too?? I am all ears to suggestions. Thanks!! If this is not a good choice, there is always the go to Paulding, Ohio!!!! Mike

Mazon Creek Best Of The Best Archisymplectes Rhothon Schram, 1973
RCFossils posted a topic in Member Collections
Archisymplectes is an enigmatic worm from the Essex portion of the Mazon Creek Deposit. It is always preserved as just a color difference within the concretion. Specimens are nondescript preserving a basic worm shaped body without segmentation or any other obvious structures. Some specimens preserve an everted proboscis. This proboscis is what led the original author to classify it as a Nemertean or ribbon worm. There are no clear Nemerteans known in the fossil record however there are possible candidates dating As far back as the Cambrian. Ribbon worms are fascin- 3 replies
