I was wondering if there are fossils along the Mississippi in Iowa? I am going there soon and wanted to hunt!
-
Found these and a few other things, including petrified wood, modern bone, old looking mineralized bone and new looking mineralized bone, and brachipods in small chunks of limestone. All found in a streambed in Ames, IA just north of Des Moines. Vertebra is flattened, and I'm fairly sure the thing in the middle is a crushing shark tooth. New to the area, geologic map said pleistocene deposits only. Thank you

Asking for a friend. Found in a stream where pliestiocene mammal material can be found. Wondeting if this is fossil, or just a cow tooth.

Our fossil group met at a quarry this past Sunday, an annual event that I have attended for years. The rock is 98% Devonian, but a bit of occasional Pennsylvanian and Mississippian exists on top. This year, for the first time, I stumbled onto a new type of rock. Unfortunately it was in a large pile so the source could not be determined. When split, it contained flat strands of darker material that to me mimics carbonized plant debris on both sides of the specimens. Minerals are common in the quarry and this may just represent some sort of staining. Hopefully someone can recognize what is in the matrix.

A friend asked me to look at this fossil he discovered at the base of a limestone bluff in NE Iowa it is a Native American winter camp and cave complex. Have found trilobite and marine fossils in the area. It looks remarkably like a tall molar or short bone but a couple hundred million years too old. Does anybody recognize this? My best guess is that is a stalk of a plant precursor?

I found this in a landscaping bed in Des Moines, Iowa. I think it's made of some kind of shale because the breaks in the rock are very clean. However, I am not a geologist. Thoughts?

A sizeable mineral coming from the ever famous Graf roadcut that exposes the Elgin of the Maquoketa. Im thinking calcite, but im gonna be honest I haven't a clue.

These fossils come from Botna Bend in IA, in the Nishnabotna River and are late Pleistocene age, can you all tell me what you think these peices are? From my tell its some kinda herbivore jaw chunk, maybe a horse hoof and this flat peice I have no idea.

I was on a walk and this rock had broken away from the bluff and was on the trail. Does anyone know what the fossil is?

Hello, This is my first post here on the forums. Please be gentle So I found this piece when I was out searching for coral (Iowa). I haven’t been able to figure out what I’m looking at. It looks to me like a cluster of fossils. I’m happy to answer any questions to help solve this mystery. Any insight would be great! Thanks!

A post was made a few weeks ago showing the Decorah Shale finds during my last fossil hunt of the year. During that trip, a section of Stewartville/Galena/Ordovician was visited too and I just finished processing my finds. In the bucket were a few unknowns that I am hoping to make known!!! 1. My guess is likely correct for this one. Beekite? I notice on the picture that that a piece of Isotelus trilobite is peeking out in the lower left corner and is probably the reason for the beekite formation. I have searched through Galena countless times and have not run into this before. 2. This one has a distinct ridge running down it and has more subtle ridges running perpendicular to the central ridge. They are difficult to see in the photo. 3. This small almost circular fossil (4mm) has a peculiar ridge down its center. 4. Finally, this "cross" measures 8 mm. It does not appear to have characteristic of a bryozoan on its surface. If it is part of a deeper fossil, I was wanting to know what it was before I explore further with my Dremel.

A couple months ago I took a trip to collect in the Middle Devonian of Iowa. It was a pretty good trip. I found some nice stuff and chatted with some very nice folks. Here are a couple of my finds. A partial ptyctodont tooth plate A neat sponge. I believe the genus is Astraeospongia but please correct me if I'm wrong. I was told these are rare from this area. A partial nautiloid And a partial Eldredgeops norwoodensis

Ive got some business in Coralville, Iowa so I did a walk along the river whilst I had some time to kill. Fossil corals everywhere which is no surprise as that’s where the name comes from. Here’s two. The walk along the Iowa River was really peaceful. I didn’t see a soul.

I am pretty sure this is Aulopora. My understanding is this coral grew on hard substrates (rocks, brachiopods, other corals, etc). Nothing in my sample shows evidence of such a material to anchor on. Can this coral exist free standing or have I misidentified it?

Traveled to Iowa for a second time this weekend. My goal was the various molt beds of Isotelus in Fayette county. Here are most of the finds. While there I stumbled upon a local hunter who was nice enough to give me all of his hunting spots. He seemed to be as surprised as I was to find someone else in the field. A few isolated hypostomes here, and some others in various hashplates. Mixtures of pygidiums and cephalon structures. I think an eye can be seen in each of these images. Some decent sized pygidiums. They were the most common part of the molt I recovered. Another large hashplate I want to display on my desk. Found this in a large block I split from someone else's derelict hole. Pieces were abundant, however no full Isotelus yet. Finally a large piece of calcite my girl found.

I've been doing some research for a couples weeks about the Isotelus beds located over Fayette county. It's been rather difficult to locate a specific site, so I'm asking if anyone who's been down there has any specifics when trying to locate them. I know of the Turkey river, but I'm four hours away so I just want to make sure I have a clear idea. Thanks, Jonah

State: Iowa Location: Graf Period: Ordovician Cruised over to Iowa for the first time in years last weekend. I went to observe and scout the famous cephalopod beds in Graf. I have to say, it was everything I had hoped it would be. The wall in which the RC was located upon, was a few hundred meters in length, and contained a few layers, dominated by dolostone, limestone and towards the bottom, phosphatic shales. I ended up finding graptolites too, which I wanted to say were Orthograptus? However I didn't bother to keep any. These were most of my finds, minus the plates I took home as well. Here was the largest hashplate, I feel like slapping this one on my desk due to the sheer chaos it exudes. Here was an unexpected find in the form of three fragmentary trilobite pygidiums. I wasn't aware they could be found here, so I'm unsure of the taxa designation. The funniest about these was I found them all within five minutes of each other. 10/10 would gif gaf up in Graf again. Next time though, I want to see if I can locate some supposed Isotelus fragment beds up near Elgin.

I was wondering what this is a snake fossil, amber stone, dinosaur fossil, or face art of some kind

I usually avoid purchasing fossils with little locality information, but this was too neat a specimen to pass up. The only information the seller had was that this trilobite was supposedly collected near Buffalo, Iowa. It looks like a Carboniferous trilobite to me, and the bedrock around Buffalo is Devonian and Pennsylvanian, hence I'm leaning towards this being a Pennsylvanian trilobite. I was hoping the knowledgeable trilobite folks here might be able to help me identify this trilobite (@Kane @piranha). I was also hoping to narrow down a possible formation/locality of origin. The only reference I've been able to find on Pennsylvanian fossils collected near Buffalo is an old post here by @fishguy – do you have any information about collecting sites in this area? @minnbuckeye As you collect all over Iowa, I thought I'd see if you might have any insight. Thanks in advance for any help.

I’m looking for help identifying this find. It is a creek find from Van Buren county in Iowa. Every fossil I’ve ever found in Iowa is aquatic (corals, crinoid, brachiopods, etc), but this doesn’t look like anything I’ve ever found. It looks like fossils I’ve seen in collections of lycopodium bark. There’s even what appears to be a stem-like core in the “center”. Any help in identification would be much appreciated
