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'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

I spotted this on the outside of a concretion this week while sorting some buckets. It looks to me like it is possibly a wing, but it's pretty water worn so it could also just be a suggestively worn fern pinnule. I was hoping for a second opinion. @Nimravis @stats @deutscheben @RCFossils @Mark Kmiecik @flipper559 Thanks. A couple shots under a microscope.

@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

This concretion opened up tonight. I'm not entirely sure what it is. I thought it might be a cross section of a small bone, but I could also seeing it being some weird pyrite formation - the site that this was collected at produces a lot of those. Any thoughts? A couple shots under a microscope.

As with many Mazon Creek pieces, a lot is left up to interpretation and imagination. Looking to see what people think about this piece. @RCFossils @stats @Mark Kmiecik @connorp @deutscheben and any other FF members.

I had this concretion open today. I immediately noticed what I believe is a coelacanth scale, but on closer inspection there looks to be some other bits that might be related. Any thoughts? @jdp @RCFossils

Help Identifying possible organisms from nodules of Pit 11, Mazon Creek Part 2
Joseph Fossil posted a topic in Fossil ID
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? -
Help identifying possible organisms from nodules of Pit 11, Mazon Creek
Joseph Fossil posted a topic in Fossil ID
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? -
Part 2 Fossil hunting trip in Utica, Illinois October/29/2022
Joseph Fossil posted a topic in Fossil Hunting Trips
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- 28 replies

In a nod to Ralph’s entertaining post, I thought that I would start a thread that I can continue to add on to over the upcoming months. With the Pit Eleven collecting season coming to a close, I decided to venture out one more time before the season ends on September 30th. Pit Eleven is a difficult site to collect due to the heavy overgrowth (lots of thorny plants), uneven terrain and did I mention the bugs. Late Summer/early Fall is especially tricky because unlike the Spring, the vegetation is in full growth obscuring many of the areas that can produce early in the year. The o

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 had this Mazon Creek concretion open today. It was collected from the Braidwood biota (freshwater/terrestrial). My best guess is a partial millipede (Amynilyspes?) but I'm not sure and wanted to get other opinions. Thanks for any help. @Nimravis @deutscheben @bigred97 @RCFossils @stats @flipper559 @Mark Kmiecik

The Fossils of the Essex Quad in Kankakee/Grundy County Illinois
Joseph Fossil posted a topic in Fossil Hunting Trips
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 -
An idea for a Museum solely dedicated to the Carboniferous life of Mazon Creek, Illinois
Joseph Fossil posted a topic in General Fossil Discussion
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 -
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

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 ?

2022 I&M Canal Corridor Fossil Trip - August 27th and 28th, 2022
stats posted a topic in Fossil Hunting Trips
The annual I&M Canal Corridor Fossil Trip was split between two weekends this year. Saturday, August 13th and Sunday August 14th, 2022 were family and beginner days, while more experienced collectors had their opportunities on Saturday, August 27th and Sunday, August 28th, 2022. From the look of what was found, the families barely made a dent in the supply of fossils. In case you are not familiar with the history of the site, the Kodat/Benson farm is designated as a National Historic Landmark in 1997.

2022-09-17 ESCONI Field Trip to a Spoil Pile Near Danville, IL
stats posted a topic in Fossil Hunting Trips
On September 17th, 2022, ESCONI held a field trip to a coal mine spoil pile near Danville, IL. It was a fairly hot day with temperatures in the upper 80's. However, it was a productive field trip. There had been quite a bit of work on the hill this summer and it was looking quite different from the spring. The road to the top went around from the left instead of the right. There weren't as many exposed fossils in "Red Dog" found this time, but concretions were readily available for collecting. There were a few Forum members present. @deutscheben @connorp I'm sure I'm forge- 6 replies

I will be using this thread to post what I have found fossil hunting in the Mazon Creek area, including the ESCONI Braceville pile, Mazonia/Braidwood, and any other sites I get a chance to explore. Although I had been to Mazonia a few times previously with virtually no luck, my first successful trip was with ESCONI last September at the private spoil pile they have access to. These first fossils are all from there. I have tried to give the best IDs I can- please jump in if you think I have anything wrong. I also forgot to put something in for scale on this first batch of photos, my apologies.

Today was the late Summer ESCONI Braceville Shaftmine collecting trip. Well it was the first day, tomorrow will be the second day of the outing. Today’s trip ran from 9 am - 3 pm. I arrived early and unpacked my car. I try to bring a number of fossils that are dumped out for the participants to go through around noon time. Today I brought a potpourri of fossils that included a bunch of opened Mazon Creek fossils, Pleistocene/Pliocene shells from Florida, Oligocene mammal fossils from South Dakota, Cretaceous Pierre Shale ammonite / bivalves from South Dakota, Mississippian fossils

Esconichthys with potential soft tissue donated to field museum
TheRocksWillShoutHisGlory posted a topic in Partners in Paleontology - Member Contributions to Science
I donated the below specimen to the Field Museum of Natural History. It is identified as an Esconichthys apopyris. Work is being done on redefining/solidifying the categorization of this species, and a professional helped facilitate my donation to the museum. There are details on this specimen such as a yolk sac and I look forward to hearing if there are internal details such as vascular structures. I feel like I can see them but I am excited to open it up to professional analysis through donation to a research institution.- 7 replies
