Need help identifying this tooth which was found in the Mississippi river near the confluence of the Mississippi and Illinois rivers. The river bed is constantly dredged to pull sand from the bottom of the river to the river bank. Area is near Saint Louis, Missouri, USA.

Today I went on a dual club field trip (Earth Science Club of Northern Illinois and Rock River Valley Gem and Mineral Society) to an Ordovician aged quarry in Roscoe, Illinois. It was a hot day for fossil hunting, but a cool breeze kept things refreshing. There were over 20 people on the trip and everyone was finding fossils of some sort. Some pictures of the quarry.

5/13/19 Oglesby, IL Roadcut- Pennsylvanian shark bits, brachiopods and more
deutscheben posted a topic in Fossil Hunting Trips
A week ago today, I took the day off work to hit one of my favorite sites, a roadcut above the Illinois River in Oglesby, Illinois. This cut exposes the Pennsylvanian LaSalle Limestone member of the Bond Formation and produces abundant brachiopods as well as occasional other fauna including gastropods, cephalopods, coral, trilobites, and shark teeth. The weather was perfect, sunny but not too warm, when I pulled up. The cut is a somewhat unstable slope of cobbles and boulders of varying size, almost all with at least some fossils in them. To get up to the slope, you have to hop across a small ditch with running water. I have a good sampling of the common brachiopods from here, so I am looking for unusual fossils when I go now. I was very happy to quickly find a piece of trilobite as I started to search the rocks at the base of the hill. (I will put pics of everything I brought home in a response post) One interesting find that I was not able to bring home was this Linoproductus brachiopod with some shell preserved and a really pretty dendritic pattern on it- it was very delicate and firmly embedded in the middle of an ~80 lb boulder. I was able to stay for 4 hours, and I felt like I gave most of the site at least a quick look. I am very happy with what I found- I was able to check off many of the rarer things I was looking for, including shark teeth, a trilobite, cephalopod material, and a brachiopod with spines attached, as well as some nice crystallized brachiopods. I will post all of my finds below.

@piranha @GerryK Can anyone confirm this is Paladin transilis? I found this in the Carboniferous of Illinois. Not sure if they've ever been described here...... And yes it's preserved in pyrite.

Hi All, I took a trip to Mazon Creek recently with my family. It was the first time that we had visited the site, and we came away with a few concretions. One piece of a concretion that we found already split in the field seemed to have an elongated impression upon it. We're not quite what organism could have created the impression, or even if it is a true fossil at all. Perhaps it is part of a marine worm? We'd love to hear what you all think about it.

Hi everyone, After the thunderstorm yesterday, me and some friends drove up to the Ponderosa area of Mazon creek park to look for fossils. It was our first time, and we didn't know the specifics of what to look for, but we spent three hours walking the whole perimeter of the lake, braving the aggressive swarms of biting insects. Can anyone here tell me if any of the rocks we found are the right ones to possibly contain fossils? Attached is a picture of all the rocks, and an album with closeup pictures. https://photos.app.goo.gl/XoCZQJwgWU7dbcoS7 Thanks a lot!!!

Greetings, all! I am currently writing a thesis involving fossils from the Burlington Limestone near its type section along the Illinois/Iowa border. To demonstrate the diversity of the crinoidal remains from the limestone (over 400 species have been described from the Burlington alone!), I am looking for photographs of articulated crinoids. Do any of you have any that you would like to let me include in my thesis? If possible, I would like high-res images of crinoids identified to genus or species with a scale bar/ruler present in the image as well as the collection/locality info. I can't guarantee that I will use every image posted, but if I use your image, then I will acknowledge you in my acknowledgements and give you credit for the image. Thank you for your time & assistance! -Elasmohunter

Hey! I just took a trip out in the pouring rain to a road cut in Oglesby, Illinois. This road cut exposes the Pennsylvanian LaSalle Limestone member of the Bond Formation (thanks to @deutscheben for this info!) I found lots of beautiful brachiopods, but as I was heading out, this guy caught my eye. What do you guys think?

Yesterday i found a very rare Megalichthys jaw with dozens of teeth still attached in the Carboniferous of Illinois, USA. This is possibly the best known example of this fish found in Illinois. Not sure yet though. I still need to do more research. You can see four larger teeth in cross-section on the matrix waiting to be prepped out. Then there are smaller teeth in-between the larger ones, maybe 4× smaller. I also found several large scales. I'll attach the best one. All of this material still needs a proper repair and prep job. The preservation on this material is just stunning. I'm not sure it could get much better. These bone fragments and scales are often found with Orthacanthus teeth and Calamites. So it gives us such a beautiful snapshot of the environment at the time. Just awesome! Happy hunting

So being a newbie in hunting fossil’s I decided to go somewhere near. I went to the creek and collected rocks which I thought were nodules, to find out they aren’t. Is there any advice on where to find the fossils and what they look like.

I posted this find in my trip report thread http://www.thefossilforum.com/index.php?/topic/95184-51319-oglesby-il-roadcut-pennsylvanian-shark-bits-brachiopods-and-more/ but I thought I would put it here too to get some more eyes on it. This piece is from the Pennsylvanian LaSalle Limestone member of the Bond Formation, collected on 5/13 and prepped some over the weekend. At first I thought it was the root of a shark tooth, but as I prepped and revealed the multiple "teeth" on top and the ratio of root to teeth it did not match up. That makes me think it is possibly a part of a jaw with teeth in it, but I have never found anything like that at this site before, nor have I seen any reported from this formation. Any ideas? The scale below is in CM.

Hi everyone - I need some help identifying a few of the Mazon Creek fossils my father and I found over the last two years. I will first apologize for the blurriness of the images, I must have had something on my lens. But, I can take more if necessary (just not today!). Here's the link to the images: https://imgur.com/a/yRaND6K I have three plants, something that's just parallel lines, and something that looks like a shrimp. Any help would be appreciated!

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!

Hi folks. Found a rock in our pasture, and am wondering about the imprint on the side. A search turned up this forum, and I thought it might interest some of you. I attached 3 pictures. After reading your guidelines I see that it suggests pics from 6 different angles, measurements, etc. At this point I don't have those. If you want them I'll get them over the next few days. The first pic shows my Wife holding the rock. I figured that gives a reasonable sense of scale. The following 2 pictures are of course closer views. The rock was found on a steep hillside in a pasture in Illinois. About 70 miles NE of St. Louis. I assume it was uncovered by erosion. Our soil is not rocky, but rocks of various types turn up from time to time. The boss (my Wife) said it looks like teeth marks. I think it's a tire mark from Fred Flintstone's car. I hope you guys have a sense of humor. And that you can shed some light on just what exactly this is.

Hi, everyone. Old fart from Illinois. Mazon Creek is my specialty. Lots of flora, not much fauna. Used to be a generalist, then started collecting Mazon Creek fossils in '91, and wish I had gotten into it sooner. I have about 600 specimens in my collection. I'm 67 yo now and haven't been out collecting in years because of greatly decreased stamina and minor health issues, but enough of them to make field work a part of the past. Just joined to poke around a bit and see what people are finding.

Fossil hunting season at Illinois's Mazonia-Braidwood State Fish and Wildlife Area, the iconic Pit 11, runs from March to September every year. I didn't make it to the park at all last year, so I wanted to get out there on day 1 this year. I took the day off work and thankfully the weather cooperated- it was cloudy and in the 30s for most of the day. I picked up my rental car at 7:30 in the morning and hit the road for the 90 minute drive north. I wasn't the first one at the park, though- I saw a few other folks heading out on the trail with buckets in hand as I pulled into the parking lot off 5000 N Rd. Although I have been to Mazonia about 6 times in the last 5 years, I am still finding my way around the overgrown landscape of the park. I started out with an area I had been to before, and had some early success. Unfortunately, I followed that by wandering off to explore a new area, lugging my heavy bucket through heavy brush for 2 hours with almost no success. That (and the fact that I was in the early stages of a head cold) led me to taking it easy in the afternoon. I was only able to add a few more concretions to my bucket, but the sun did peek out briefly towards the end of the day resulting in some lovely panoramas from up on top of a ridge. I was able to chat briefly with another fossil hunter when I got back to the parking lot about the joys and tribulations of fossil hunting at Mazonia- we discussed the hard work necessary in order to have a chance to open an incredible window into a 300 million year old world, and how we wouldn't trade that chance for anything. I finished the day at the former tipple on the western side of the park, wide open ridges of dumped waste from the former mine that remain inhospitable to plant life to this day. It is an alien looking world, and usually has not been a great spot for finding fossils. However, it is easy to access at least and I was actually happy to come across a few rough bark impressions in sandstone that I picked up. The sun was getting low, so I decided to call it a day. I only collected about 1 1/2 gallons of concretions, but I was still glad I could get out to the park and find something. I will put my finds in the next post.

Hello, I am planning on going to Mazon Creek for the first time this weekend and was wondering if I could get some advice. I have fossil hunted at the Peace river and Shark Tooth Hill, but despite living in Illinois, I have never been to Mazon creek. I am not sure where I should start looking. I have read some of the trip reports on the forum and most seem to suggest either around Pit 11 or south of W 5000N road. How long does it usually take to get to productive spots? I read that some people have to hike for an hour before finding fossils. Also, where should I park my car? How much time is usually spent at Mazon creek? Is it an all-day event or just a few hours? I was planning on attending the ESCONI gem, mineral, and fossil show on Saturday morning (3/23) and then heading Mazon creek afterwards. Will I have enough time? Thanks in advance for any advice.

I am a new person and not a paleontoligist. While swimming in the Rock River Moline Illinois 52 years ago I found this bone deeply buried in the mud. There was much more to the find than what I could bring up, but this piece could be lifted free by unburying it with my feet. It was in 3-4 feet of water. it is 12 inches long and weighs 1.8 pounds. I would appreciate any input someone has time to offer please! All these years, I still have the bone and I do not know what it is. I have other photos but this site will not let me upload them. Thank You

Hi, I found this tooth the other day near Starved Rock, Illinois. Pennsylvanian deposit, Livingston limestone. I can't seem to find a match. It's missing some bits, any ideas from the paleozoic shark experts? It measures about 7mm
