I had to make a trip to the "big" city of Rochester, Mn today. As I drove by a new building site that exposed some Decorah Shale, I had to make a stop. The Decorah Shale is an impervious layer that keeps pollution from seeping into deeper rock layers and contaminating our ground water. Obviously, building permits are being obtained without adherence to the zoning which prevents interuption of this great geologic feature! I will drink my own water but collect fossils from these ill conceived sites. While visiting such a site, I discovered this tiny gastropod that I can not identify.

Hey Fossil Gang, I had a surprising find along Canon River in Northfield Minnesota (coordinates 44.461901, -93.158759). I was skatingboarding and noticed that the banks of the river were pretty rocky so I thought it would be worth investigating, sure enough I found what appeared to be some sort of bone attached to a piece of rock protruding about half way out of the sandy soil. To me it looks like some sort of mammal jaw although I'm not sure (new to fossil hunting). I'm not sure but it seems to be more modern. If any of y'all have any input it would be greatly appreciated!

Hey Fossil gang, I went out into the hillside forest next to my dorm and found some shells scattered about. It's very possible they're simply snail shells - I'm very novice. Any help would be greatly appreciated, thank you.

Hey Fossil Gang! I was exploring the forest near my dorm and found a small area where the ground had a sparse layer of tiny, white, spiral shells. I'm no expert but they didn't seem like snail shells, I could be wrong. I was wondering if anyone could give me some tips for this situation. What should I do? I thought I could start by collecting some of the surface level shells and maybe even dig around a bit. I imagine just the tiny shells would be pretty common but do y'all think there could be greater treasures laying in wait? What sort of basic equipment/tools should I use? Any help would be appreciated! I'll post if I find something cool.

Just found this in the same spot as a bison tooth in an antelope tooth fossilized
-
I found this tooth while fossil hunting can anybody help identify what animal it came from and if it's old or more recent? I appreciate any info. Thank you! I'm new to this forum just a fyi

Any one recognize

I found this and was wondering if anyone thought it was a fossilized because of the blue I found it with fossilized bison teeth teeth had the same color blue

My son found this in the Mississippi River in St. Paul, MN. I thought maybe it was a scapula, but I really have no idea. Anyone out there know what it is? Thanks!

Searching the gravel driveway for a missing piece of a telescope (at night...), I pocketed an odd rock. In the light of day it looked to me like it could be a tooth. I'm located in McLeod Co., Minnesota, not at all known for fossils, but the glaciers have brought us a few surprises that show up from time to time. Fossil Forum members helped me ID a piece of petrified wood from the same gravel drive 2 weeks ago. Or maybe it's just a rock. It has several cracks or grooves that run most of the way from the potential "crown" to the "root." Thoughts? BTW, that's a marshmallow I used to stabilize the rock to display the possible "crown" and "root." Later I ate the marshmallow.

Hello. I was wondering if I could get any more information on this tooth. I purchased it from our favorite auction site. The seller described the tooth as unknown genus/species and from the Cretaceous Coleraine Formation of Coleraine, Minnesota. I was unaware that Minnesota had Cretaceous sites? I almost didn’t believe the location provided. I looked up the Coleraine Formation and found that it was Late Cenomanian in age and located really close to Grand Rapids, Minnesota. Based on the age and morphology, I have IDed the tooth as Cretolamna appendiculata. Does anyone else know about Cretaceous shark teeth in Minnesota? Please share anything you know and post pictures of other finds if you have them.

Hello - I'm a new member of the Fossil Forum. I'm excited to learn more here. I would like to find out if the more experienced folks think this is petrified wood? I found this rock in our gravel driveway in McLeod County. It looks like water-worn wood to me, and seems to have a clear grain to it. It is about 1 1/2 inches long. I have found several similar rocks while running within 3 miles of my home along gravel roads (usually I pick them up mistakenly thinking they're agates). The Science Museum of MN positively identified one of them (not pictured here) as petrified wood. This one, however, doesn't have the same agate-like sheen. Thank you!

The fossil was collected on the Deer River near Spring Valley, Minnesota. It is shaped like a trilobite, but it doesn't have any distinctive features, as the shell is mostly smooth. It somewhat resembles a shark tooth, but were no fish at this time. The width of the fossil is about 17 mm.

I cleaned it up quite a bit, picked it up thinking the top part of the tooth was a beautiful agate , was not disappointed though!

Due to an upcoming order from our Governor to stay at home, I took the opportunity to fossil hunt last Sunday afternoon before it begins. The ground was white with an unexpected snowfall overnight when I left the house but soon melted. My goal was to look at road cuts for rock slides from the winter's freeze thaw cycle. Digging and splitting would be tough with frost still in the ground. The first spots searched were Ordovician, Galena. Here are a few representative fossils from the Galena of SE Minnesota: From there, I slipped over the border into Iowa to look at Ordovician, Maquoketa. A sluffed hillside provided me with some rock that I wasn't that familiar with. Here are some finds: The first picture is almost clay like, different than the normal Maquoketa that I am used to.

A ny insight?this is the only rock I found today that look like it could be fossil related trying to learn and grow thanks guys

I was wondering if anyone knew any good places to hunt fossils or rocks in Minnesota where I live or Wisconsin

I found this plate near in the upper decorah formation Minnesota (Ordovician period limestone). These chunks are frequently littered with trilobite bits and fragments but this lookk a little odd to me. It has a "knob" or bump structur on one side and a gradual bend on the other. Its still partially covered by coral and debris but most of it is exposed. Any ideas?
-
I found this chunk of shale poking around a bluff side a while back near Lilydale Park in Minneapolis, MN. The fragment pictured is translucent and is slightly concave, it reminds me of a cheek plate but Im not sure. I'm new at this so I'm pretty clueless, I appreciate any help.

Does anyone have experience with the Middle Ordovician brachiopod faunas of the upper Mississippi Valley? I came across this odd fragment in rocks from a quarry in south-central Wisconsin. To my knowledge they are known in North America only from the Appalachian Basin (Tennessee, Virginia, West Virginia, Pennsylvania, Quebec, Newfoundland), not the interior basins like the Illinois basin. Has anybody else seen this critter or similar in the Platteville? As far as I am aware, the only species documented from the Platteville that looks anything like this is Megamyonia unicostata, but that has a single costa rather than the several apparent here and in the types of Ptychoglyptus. Platteville Fm, probably in P. undatus biozone = Upper Ordovician, Sandbian stage (old North American Turinian Stage)

Locally, graptolites are very common in the Maquoketa/ Ordovician rock. They present themselves as 2 dimensional creatures on certain bedding planes. Below the Maquoketa is our Galena. It has graptolites but uncommon. Again, they present themselves as 2 dimensional. The "unknown" specimen from the Galena, presented today, is obviously 3 dimensional and I venture a guess that it is a Graptolite. But I thought I would seek opinions in that I have seen thousands of local graptolites but never one that is 3 dimensional. Could it be something else??

Hello found this damaged skull on a rock bar in southern Minnesota. Thoughts on what it could be from? Insert existing attachment

Hello - found this damaged bone on a rock bar in southern Minnesota. A triangular piece is broke off the the proximal end. However looking at the other end, which seems intact, it does not look like bovid which is what I usually find...
