A few weeks ago, just when we were inundated with the spring muddy season, I stopped at a site that features Decorah Shale with a little Platteville mixed in. If you haven't collected in the Decorah Shale, let me say it stays MUDDY even in a drought!! The site had been worked over for a finish grade. This means the site will soon be lost to vegetative overgrowth. So I proceeded to collect a 5 gallon bucket of mucky matrix to clean and examine at home, in case the weeds invade quickly. Here are some select finds from that bucket.

In September, the desire to collect the Burlington Formation, Mississippian of Iowa got the best of me, “forced” my truck to make a little road trip down that way. The trip was about 4 hours, necessitating an overnight stay. Covid was running rampant, compelling me to sleep in the back of my pickup and eat out of a cooler full of food instead of motels and restaurants. This left a 64 year old man a bit stiff in the morning. The nice thing about the Burlington, it did not tax my body too much, allowing me hunt my allotted 8 hours with ease. Normally the Burlington is searched for crinoid specim

Found this fossil recently while visiting the Fossil Park near Rockford, Iowa. The fossils here are Devonian in age, and belong to the Hackberry Group/Lime Creek Formation. Have found numerous varieties of brachiopods, horn and colony coral, gastropods, bryozoa, and pieces of crinoid stems, but have never seen anything quite like this. Since it was such a crappy day, I had the whole park to myself except for one guy from Minnesota. Thinking he might be more knowledgeable than myself, I asked for his opinion on what he thought this was. He suggested it was definitely a crinoid calyx. I am not s

The colder days of late has allowed me to work on the Burlington matrix that I brought home this summer. It has revealed some real treasures, at least for me. But I am stymied on a few finds and look for some opinions of forum members. 1. A few questions on the first piece. My goal was to clean up a large piece of ??? Shark spine? While cleaning, two teeth were uncovered. Here is the "backside" tooth. Now the "front side" tooth Initially just the tip of the tooth was showing, but as I progressed with cleaning, this "moustache" was exposed

I graduated college back in May, and since my graduate program did not start until September, I was fortunate to have quite a bit of time this summer to explore further away from home. I've been slowly prepping and cataloging over the past couple months, and figured I would share some of my favorite finds that I haven't shared yet. First up is dump piles of Silica Shale (Middle Devonian) in Paulding, OH. My university was not far from here, so this is really where I started fossil hunting. I've been here quite a few times, so most of what I found I already had in

I'm slowly making my way through finds from the summer and have come across a couple specimens I don't recognize. The first one is from the Platteville Formation of SW Wisconsin (Middle Ordovician). The second one is from the Maquoketa Formation of NE Iowa (Upper Ordovician).

It was about a month ago that our Fossil Club was going to meet at a Devonian location in central Iowa. The first cold weather of the season hit just then and required heavy coveralls to stay warm, so my sights were not set too high for this trip. I decided to make it a 2 day hunt and sneak down to SE Iowa the first day. My goal was to attempt to find some shark teeth from the upper Burlington Formation. The teeth from this location are extremely fragile and will turn to powder if touched with anything but kid gloves. This is a lesson that I have learned from multiple times collecting with li

Two weeks ago, I traveled to Central (Devonian) and SE Iowa (Mississippian) for a little fossil hunt. It was very successful and I will complete a trip report soon. In the meantime, it would thrill me to understand a few unknowns from the trip. First of all, the Mississippian, Burlington Formation: 1. and 2. 2. is a brachiopod that I could not find in the lists of brachiopods from the Burlington Formation. 3. There were many of these present in a certain layer of rock. Very circular with longitudinal striations.

The other day I went on a annual trip to a quarry in Iowa. Givetian age rocks. Finds were few this time around, for me at least. This was my best find, although not perfect or complete, still a nice example. It was tricky to prep as I didn't want to destroy the reddish- mauve brachiopod contrasting nicely with the caramel colored E. noorwoodensis. Thanks for looking!

Fossil Plants From Cave Deposits, Near Pella, Marion County, Iowa lepidostrobus Sp. Brongniart- arborescent, 310 Mya old, Club Moss locality, Pella, Iowa Formation, Pella Beds Age Pennsylvanian The Lepidostrobus is the generic name for the cones of arboresent lycopsid. It corresponds closely in structure with the fertile spike of the living Selaginella. The spore-bearing leaves are attached to a central axis in a crowded spiral arrangement, and their outer ends curve over so as to form an imbricated, diagonally arranged pattern, resembling that of the stem i

Planning a serious Iowa excursion for my Uni before winter hits. Was curious if any of you have done any rockhounding around the Le Grand area. Apparently is a site for exquisite crinoid plates. Just curious before I start calling the stone company and procure access/permits/etc. https://www.legrand.lib.ia.us/Library-information/fossils/crinoidfossils was sent a link to this by a contact at UNL...hence my sudden interest https://www.iihr.uiowa.edu/igs/publications/uploads/Em-04.pdf

I read a lot of fossil hunting reports on here, but I don’t post many. I think it’s primarily because it is usually many, many months after I have gone when I finally get everything cleaned up, ID’d and take photos, etc. It just seems too after the fact to me at that point, haha. But this time, due to a wonderful “tour guide” we had, I wanted to get something posted in a relatively timely fashion. Because of that, I haven’t had time to do a lot of research I need to do on specific ID’s but luckily I’m somewhat familiar with most of what we found to make at least an educated guess.

These two finds are stumping me a bit. Both are from the Maquoketa Fm (Upper Ordovician) of Iowa. The first one initially struck me as a 3D graptolite, but it could be a crinoid stem. I couldn't get a good photo of the cross section, but it is rectangular.

This is a tusk I recovered from a river sand bar in Iowa 24 hours ago. The tusk was in somewhat damp sand. It started to degrade right away once it was unearthed. I wrapped the tusk in a towel but it did dry out a bit. I got it home about 5 hours later and re-wrapped it in damp towels. I am writing this post to spell out my plan based only on reading some other posts but not based on any experience. I would appreciate any advise. What am I missing or doing wrong? -Add many zip ties to hold tusk together. Leave crusted-on sand for now. -Wrap with damp towels

I am undecided if this is fossil or dendritic deposits on a rock. It is from Keokuk limestone, Mississippian.

I found this today in the yard while doing some light soil work. No idea where it may have come from. Thinking it might have come up from the frost over the years. Look like sinew or even fat tissue when I saw it buried. After bringing it up and cleaning it up thought it looked like a giant arrow head. Then it even appeared to look as though in the pointed portion on the item it had what looked almost like growth plate lines like we have in our bones. The stub end looks a lot like a joint or knuckle of some point. We are located near the Iowa and English river basin's In Iowa. Any help would b

Another post regarding a specimen I found posted on a Facebook fossil ID page - which no one in the group can ID. This was found in a river in Iowa. Most of what is found in the area is Pleistocene to modern. My first though was part of a turtle shell attachment point? But I am stuck.

Hi, I found this in Pensylvannian glacial till around a reservoir. It’s about 12” long by 5” in diameter. There are coal seams nearby. I think it’s a lycopod part of some kind but it doesn’t match most of the pics I’ve seen. Can anyone tell me more? I’m curious about the layered appearance. I don’t think it was in its original location as it was stacked on a big rock with other specimens. I left it in place due to regulations. Would have liked to keep it! Thanks!

I recently bought this jaw and was wondering if someone can shed some light on it. Seller gave some info on it, but when I received it it’s a little different than expected. Seller states it was found in Iowa. It also seems very light if it’s fossilized, I have no experience with fossil bone so I’m not sure what to expect. Any help is appreciated. Thanks
