Hello, I am a local undergrad geology student working on a research project dealing with Mazon Creek's Braidwood and Essex Biota. As part of this research, I am required to collect specimens and data on both of these assemblages present. I have been informed that any access to the Fish and Wildlife areas in the Mazonia-Braidwood South Unit is prohibited due to the Illinois DNR's indefinite closure of all fish and wildlife areas, so I am taking this time to research and inquire about access to both assemblages for future reference. That being said, my questions are as follows: Are t

Hi all, I've had this Mazon Creek fossil in my collection for a few years now. It is labelled as a Tully Monster, and seems to match up with other Tully Monster fossils I've seen on the forum and online, but I am by no means an expert, so I would appreciate any help with confirming the ID!

Here's a new find from the I&M trip last weekend. The nodule was full of indeterminate plant fragments, and I almost tossed it until this one small bit (~1cm in length) caught my eye. Maybe a wing fragment or am I being hopeful? The texture is much different than what I've seen in plants, but that's a bit hard to capture in pictures. I can try to get better pictures tomorrow in the sun if needed. As usual, any thoughts are much appreciated.

Fossil Forum members were well represented at the Illinois Canal Corridor Association's Mazon Creek collecting event this weekend. My wife and I were able to make the 11 hour drive out Friday to join them and we enjoyed a productive afternoon in the creek Saturday gathering several buckets of concretions to take our first crack at freeze thaw. We also found a number of already opened specimens to wet our whistle while we do our best to be patient. Here are some of our better finds even if some are a little water worn. New to us, so the trip is already a success regardless of what

Here are two interesting Mazon Creek flora nodules that popped yesterday. I believe they are both assigned to Rhacophyllum. If so, I am excited, I have not come across this "genus" before. Rhacophyllum cornutum Rhacophyllum fucoideum I am pretty confident on the IDs but confirmation is always great. I am quite interested however in the second specimen. It appears that there is a root-like structure emanating from the central base. I cannot find many images of R. fucoideum online so I am not sure if this is significant or not. As usual, any though

Here is a few of my Lucky finds for 2019 Mazon Creek fossil collecting season. I will try to keep adding to it as time and posting ability permits. My wife and I collected 14 times in 2019 at 4 different areas. We had a great time, met many great people, learned a great deal, on our adventures. Anyhow, I'll give this a try, and apologize in advance for the less than perfect photos. Phil

I thought I jump on the bandwagon of Mazon Creek and show my little collection. I’ve been picking up the odd fossil here and there to add to my allotment. This has been over the last 5 years. Originally I was introduced to the ironstone concretions by Ralph in one of his great auctions to support TFF, which I was lucky enough to win. The first 3 added after the collection photographed in the drawer, I could do with a little help for identification please. 1: sea cucumber, 2: worm, 3: Has a label but it is only the seller’s info ? thank you help and for looking.

I decided to take the time and try to shoot pictures of slides that I received years ago from my Fossil Mentor Walter Lietz. They are slides that he would show and talk about at the various Fossil talks that he would give prior to us taking the participants out collecting. This post may take me a couple days to complete due to the number of slides that I have to take pictures of. I have tried to do this before, but the machine I was using made it difficult. This time I am using a lighted hand held slide viewer and shooting them with my I Phone. It is tedious, since I then have to e-mail them t

This concretion opened today. I cannot decide if it a poorly preserved syncarid or more hopefully a partial centipede (Mazoscolopendra?). Any thoughts? @RCFossils @Nimravis @flipper559 @bigred97

Hey Folks, Here’s another I’m not certain about. Trace fossils, perhaps?

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

Hi all Just a quick question , I have been very interested in the material from Mazon Creek since I won a great auction lot from Ralph that included a few fine specimens . While looking today online I spotted a trilobite pygidium that was labelled Mazon Creek it looks like the right type of siderite concretions but it could be from some where else . So what do we think? I don’t think they was native to Mazon creek but maybe transported there by floods ?

I am somewhat hopeful that this is an example of Amynilyspes (a pill millipede), but would like to get another opinion. It was found open and is a bit worn. @Nimravis @bigred97 @flipper559 A close up of the "tergites"

I have some questions about Mazon Creek fossils preparation. 1. How we can know that the "egg" contain a fossil? 2. How we can cut the "egg" in the correct point, without to damage the fossil? 3. When we see pos/neg specimes, how the "egg" has been cuted so accurate?

Hello all, I'm a long time lurker on the forum and a new member! I recently went on a trip to the Mazonia-Braidwood State Fish and Wildlife Area for the first time and am hoping for some assistance/confirmation on my IDs. 1. An imprint of some species of Pecopteris. 2. I'm fairly confident this is a partial Essexella adhere 3. Possibly also an Essexella asherae, but I suspect it also may be wishful thinking Thanks in advance for any assistance! I've got a few small nodules going through a fre

Hi everyone, I was going through some more of my Mazon creek material and could use some help with ids I have some ideas what these might be, but I'm still pretty inexperienced and would really appreciate some help. Thank you in advance!

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

Hi all, I just opened up some concretions from the Mazon Creek area in Illinois, USA and was wondering if I found anything. About 90% of what I opened were blanks. I've attached the three concretions that I think are something and a picture of what I was considering blanks. Thanks in advance. Blanks) 1) 2) 2 one piece opened up) 3)

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

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

Hi everyone I recently spied this mazon creek nodule on an online auction site and stuck in a cheeky bid as I thought it looked interesting. Listed as "unidentified worm from Mason creek" Perhaps preservation is too poor for a positive ID however if anyone has any thoughts as to ID please mention. Total length of feature around 3cm.
