Hi everyone! I was in SE Minnesota recently, looking through limestone outcrops where I have found cephalopods on a previous trip to Mystery Caves, MN. While looking for more cephalopods during my most recent trip to Fillmore County (and finding a few) I found this piece shown below. The fossil is likely Ordovician aged, as is common in SE Minnesota. The formation I am less sure about, but if I had to make a good scientific guess, it is the Galena formation. My question is if this is a cephalopod fossil that is just heavily eroded, of is this just a cool rock? I decided to also flip the fossil with my hand to better see the ends. Thanks for the help everyone.

Hi everyone! Longtime human recently turned into amateur fossil hunter. I currently am in the Twin Cities in Minnesota, and have been for the past 5 years. I've been enjoying lots of the beautiful nature the state has had to offer in my downtime, even during the winters which are not as bad anymore. I will say that I have always loved paleontology! That, marine biology and astronomy are what propelled my love for science, and what have pushed me to pursue a PhD in Chemistry. I never knew fossil hunting was an activity anyone can do, or even possible to do, until earlier this past summer. I had an awesome trip to the beach with family, and while everyone swam, I would walk the shoreline for hours looking for shells of different sizes, colors and species for almost a whole week. Toward the end of my trip, I went to a marine biology museum and talked to some of the curators and learned that fossil shark teeth are a usual find by beachcombers, but usually you had to have an idea of the shape or accidentally bump into it. I was so thrilled to learn that was possible, so I made it my objective to at least find one tooth by the end of the trip! And I am glad to say that I found quite a few in a couple of hours of trying! I even found a few other fossils (a small piece of soft shell turtle carapace, a crab claw, not shown) Since then, I've been trying to do some research when I can (again, graduate student so I have other research duties!) and try to explore the natural history of Minnesota. I've found the broken up pieces of braciopods shells everywhere on the Platteville limestone on the Mississippi River, as well as bryozoans, a few gastropods and cephalopods, and, as my username implies, a whole slew of crinoid segment and columnals! Crinoids just speak to me, and I find those circular wonders everywhere! Most recently, I recently went to a trip to SE Minnesota and met up with a well known Forum member and went hunting for giant gastropods. It was a super success! Even if there was certain fossils we couldn't remove. That's a little about me, and I'm looking forward to learning more from everyone around here! I'm hoping to get help with FossilID for some things that I have found, and maybe connecting with others that know the area or neighboring states like Iowa! I would love to get a general idea of where to hunt, and go on more adventures and make some friends! If you'd like to see some of my finds, I'm more than happy to post some of those here as well

I have a nice little slab of Platteville Formation (Mifflin Member) from the Ordovician of SW Wisconsin that I received from @connorp late last year. I am working on a post that describes all of the great things in it, but want to get a couple of ID's cleared up so I can be more concise in that post. Here are three trilobite pieces found on the slab that I have taken a stab at an ID, but would love confirmation/correction. Hopefully there is enough there for some of our trilobite experts such as @piranha , @Kane or any others to offer some advice. Thanks for any insights anyone can offer. Each picture is numbered in the upper left. Mike Here is a picture of the small slab with the location of the trilobites in question numbered. The sharp eyed will see another trilobite cephalon in the lower portion of the slab. I am fairly certain that one is Gabriceraurus mifflinensis. Here is the first question. This looks like the best match I can find for species listed from that formation, but I'm not certain. I wish I could get this one a bit cleaner, but the matrix left is pretty hard and stuck to the pygidium. This one may be a stretch as there is not much there, but maybe enough to be recognizable (or maybe not). Thanks for any help.

Over a week ago I took advantage of our university's Reading Week break to hop a train east to do some late season digging. Apart from a few surprise finds, it did not quite live up to my expectations. I had to hastily organize it as I had got the dates wrong, assuming Reading Week was the following week (one of my students corrected me). It meant getting the trains and motel all lined up with barely a day to spare. Upon my arrival in Toronto for a layover, someone not all together upstairs thought it would be a wise idea to pick a fight with me. I defused the situation, but it certainly help set the tone for this week-long adventure. On the first day of the dig, I ended up walking about 25km for nothing. On the next day I went back to the spot that had been so productive weeks before, but this time it turned out to be the opposite with two exceptions. Unlike last time when cheirurids were popping out like they were going out of style, not even more than a pygidial spine of one this time. Instead, a pair of crappy Flexis:

I was storing more of my collection away the other day, when I saw the eye of my Colpocoryphe specimen. Eye lenses! My other specimen has them too, but the eyes are a bit crushed. I thought it would be nice to share. I never saw these, and the second one was the first ever trilobite I got. I can’t believe I never noticed them.

Hi all! I am back again (this time in Montréal and found a peculiar looking fossil. It is very circular, almost has a subtle stippling on the top surface (which leads to think maybe a sort of precursor coral/bryozoan). It popped out very cleanly from the rocks we were excavating. The other fossil for ID is the brachiopod in the 4th and 5th pictures: Topside Underside Side Profile (its rather thin, but thickest in the middle - somewhat dish-like) Measurements Brachiopod for ID Thanks in advance! -Em

Found in a creek in Alton by the Piasa Cave. Looks like the exoskeleton of some arthropod. Any idea on what it is exactly?

Howdy all, Found these in my usual spot in the Drakes formation. The first two look like some sort of bivalve, not a brachiopod. The second looks like some sort of coral.

Howdy all, This is something I've wondered for a while. What is the relationship between the Drakes and Kope formation and what are the differences?

It's been a long time since posting a trip report, but it has been a fairly active year despite the monkish silence as I try to be fairly circumspect about locations and where I am going. Last weekend was Thanksgiving up here, but I passed on turkey to spend some time solo far from home. Some very nice finds for two days from the Bobcaygeon Fm of Ontario. Time to share. First up, some field shots from the phone. First blood was a doozy. Within half an hour after sunrise, a cluster of Ceraurus globulabatis and Gabricerarurus dentatus. Not the nicest material, but I kept all the bits. There may in fact be more buried in this plate. It got a bit rainy, but I was undeterred. The rains eventually stopped and I kept at it for another 9 hours. Here we have a scrappy Calyptaulax callicephalus. Seriously exfoliated, and a bit too delicate on a flake to extract complete. It would not be the worst heartbreaker of this trip. Getting warmer to maybe finding a Ceraurinus marginatus. This is a wide pygidial array of spines of roughly 2 inches wide. The three individuals on the left are Raymondites, with a scrappy Flexicalymene senaria on top, and that same Calyptaulax photo-bombing this image. (continued)

Howdy all, Found this in my usual spot in the Drakes formation. Looks like some sort of concretion, what do y'all think? Louisville, Kentucky.

Found two parts of this the other day in Indiana, and after more inspection I found the other part down the slope. It appeared to have washed out of the bank and tumbled down breaking it into pieces.Any Help with this would be appreciated. Thank you.

Found this today, the one on the left. Not sure that I have even seen a fragment like this. Bumpy kind of like a crab leg.

so I am new to fossil hunting but have went out the past couple days and have had a blast. But I can not figure out how to attach photos! I select add photos, and nothing happens. What gives?
-
Ok guys. I am new to this and really enjoying it. Figured I would share a few photos and hope that someone would possibly help me out here. The 3 fossils I have no clue about were found within 30 yards or so of one another. I appreciate any help, and thanks for looking! Ordovician

It has been a while since I have made a trip to a new spot, I had some free time last weekend and decided to head out towards some promising localities in Central NY for Ordovician fossils. Found a great place to go through some research and digging. I hit a couple different sections of the same area and found different specimens. I am guessing at some point I wandered out of the Utica fm. and into the Trenton fm. Pictures below, thanks for reading! I got to this one too late, but this could have been an A+ trilobite before it got weathered out. This find was pretty important for telling me which area to work in. 1. Partial trilobite that didn't necessarily break the right way with a cephalopod 2. Pyritized disarticulated trilobite partials. 3. Nice triarthrus head. Haven't done enough research to tell the difference between T. beckii and T. eatoni 4. Could be my favorite of the trip. Big cephalopod 5. Closest I got to a complete triarthrus 6. Good size but disarticulated. Found this one early. 7. This is where I believe I moved on to the Trenton. Looks like a flexicalymene cephalon. 8. Found this near the suspected flexi

9-15-23 to 9-17-23 Southern Indiana and Northern Kentucky Collecting
Nimravis posted a topic in Fossil Hunting Trips
This past weekend I spent the parts of 3 days collecting in Lawrenceburg and St. Leon, Indiana and well as up and down the AA Highway in Kentucky. Here are some random pictures of the sites I collected. Here are some miscellaneous finds- burrows, Trilo-bits, Bryozoan, horn coral, brachiopods, trace fossils, etc. My favorite finds are always hash plates. I love how they show a snap shot in time. Although I mainly collect Mazon Creek fossils, I still like nice hash plates from the Ordovician more, some of them have so much stuff going on. Zoom in on the pictures, they are really cool. Continued on next post-
