A few days ago I went on a fossil hunt with @Tales From the Shale and another friend to a rock formation of Pennsylvanian age, around 300 Million Years old, in Oglesby, Illinois. We also went to a second site in the Mazon Creek area in Braceville, Illinois. Today I decided to put some of the specimens I found under a dissecting scope to see them better and potentially get a proper ID for them. Here is a little Crinoid specimen (I think it may be the top part) Here is a nodule I found at the Mazon Creek site. @Tales From the Shale Identified the specimen as possible fossilized plant seeds.

Hi, @Dimitris and i are tryiarête join Adam, alias @Tidgy's Dad numerous times. We sent him a parcel and it came back with the mention "Refused by the recipient", that doesn't look like him at all. We sent him messages via the forum, i sent him a SMS and a vocal message on his phone but, so far, there's no answers. His last visit to the forum was the 27th of January. Does someone had more recent contact with him ?

Two days ago I went with @Tales From the Shale and another friend on a fossil hunting trip to a Bond Formation Roadcut in Oglesby, Illinois with rocks dating around 307-303 Million years ago, to the Pennsylvanian section of the Carboniferous era. Hadn't been back to the site since October 2022 and it was good to be back! I was pleasantly surprised at the lack of snow. But it was clear it only melted very recently judging by the arm sized icicles and the mud. (Quick advice for anyone planning to go fossil hunting at this time in Oglesby: bring snow boots to balance yourself on the rocks and mud, they will be a life saver). Found the usual brachiopods and crinoid bits at first, but then I found a 5cm long crinoid stem (the most intact one I've found so far from the area). I don't know currently what species it belongs to. We worked for two hours at the site before heading to another site in Braceville before heading back to Chicago. Today, I looked at some of the specimens I found and realized I found a lot more than I initially expected. Definitely enjoyed finding the large brachiopods (the second one I believe is a large Linoproductus). Found some Bryozoan (species unknown), the first I've discovered in Oglesby. Found a small but still pretty cool Cladodont shark tooth around 1-2cm in length. Currently don't know the species yet. Another cool Brachiopod (I think it's a Punctospirifer species). Also found some Petalodus teeth, Trilobite pieces, and bits of Peripristis. I'll post those and more detailed images of the others when I have access to my college's microscopes later this week.

Hello and Happy New Year to all of my Fossil Friends! Yesterday and today I put in my first 2 hunts of the year. The weather here has been mild and I almost went fishing instead. But the fossil gods were calling to me and I couldn't resist their siren song. I decided to visit a site that I haven't been to for awhile. I am sorry but a have made a New Years resolution to no longer name locations for the world to see. This is a site that I have gone a few times with minimal results. Mainly it is a rather large site and the rock is hard to work. But I knew the potential for nice finds were there. So, Yesterday I arrived in the afternoon, planning on putting in a few hours. I started off on a lower layer. Now there is multiple layers of shale mixed with slate and limestone. The way this material fractures is rather strange. Which makes recovery of specimens rather tough. So while I found many cool things most where damaged in some way. Crinoids, brachiopods, bivalves, gastropods, nautiloids and trilo Cephalons were fairly common. Some were even pyritized. I must have been there for a couple hours before I decided to explore farther up the slope. I noticed a different color rock closer to the top, but there was really no where to stand. I grabbed a couple loose pieces and started seeing parts of corals and crinoids that were larger then any I have found before. Also partial trilo bits and pieces of Eldregoeps. I looked for a way to get to the very top of the slope and found a way that was not at first obvious. And then bingo! I found a small section that was easier to work and I immediately was rewarded. I started finding abundant amounts of horn coral, large crinoid segments and a nice slab with a horn coral with a trilo right next to it and possibly more. Then I removed a chunk of rock and uncovered a huge tabulate coral about the size of a dinner plate. Unfortunately this specimen was fragile and was broke into a million pieces. But I recovered some of the larger pieces. It started getting dark so I left for home with plants to go back this morning, which I did. Today was much of the same tons of corals but one horn coral was about the size of a grapefruit. This is definitely a different species than I am used to seeing. Most if not all need to be cleaned up and possibly prepped. So I plan on trying to clean up and get the mud off. I will post pics later this evening. It looks like this year has started off with a bang. I hope it is a sign of things to come.

I recently have been reanalyzing some fossils I found with @Tales From the Shale and another friend on October 8th, 2022 at a Pennsylvanian era roadcut in Oglesby Illinois! One of the specimens I had previously put under a dissecting scope, but was still unsure about its exact ID. I recently took a look at the specimen again a couple days ago and I believe its a partial tooth of a large ctenacanthiform shark. Here is the specimen under a dissecting scope! After a closer look, I noticed the parts of the tooth that could have connected to the medial cusp and lateral cusp on the left side of the tooth. For comparison, I compared the tooth to other Ctenacanthiform teeth, including cusplets section of the teeth (between the medial cusp and lateral cusp). The number of preserved cusplets on the tooth don't seem to match Gilkmanius (which usually doesn't appear to have cusplets between the medial and lateral cusps) or the other reported bond formation ctenacanthiform Heslerodus. The closet match was Saivodus striatus, but I'm not 100% positive on the ID. Below are some comparison images with a Saivodus striatus tooth. https://www.uky.edu/KGS/fossils/fossil-of-the-month_2022-07_Saivodus.php The first image here shows where I think the lateral cusps are (highlighted with green circles) on the specimen (not dissecting scope images). The second image shows where I believe the medial and lateral cusps would have been located (highlighted with green circles) with the right side being where the medial cusp was and the left side where the left lateral cusp was. Here are the same comparison images but with the dissecting scope. I'm sorry if some of the images are really blurry (still trying to fix my phone's camera). But what do you guys think? Do you guys know for the specimen what would be a good ID for it?

Hello again everyone, I received an old collection from a married couple who weren't interested in it anymore. Some of the items were purchased in 1905! They got them from the man's father who was Dutch. Unfortunately, many of the fossils did not come with their labels, and the labels I do have are written in Dutch, and in cursive... I would be grateful for any useful information you can provide (id's, locations, ages, etc.). If the photos aren't clear enough just tell me the number so that I can send a better image. 1.Lots of these brachiopods 2.This one had a label on it, although it doesn't look too eye catching. 3. 4.Looks like a scallop 5.Small steinkerns with label 6. 7. 8. 9.Devil's Toenail Oyster? 10. 11. 12. 13. 14. 15. 16.Crinoid calyx 17.A lovely little bug 18. 19,Assorted goods. More photos on them below. I'm curious about the concretions. 20.Chalk (with microfossils?) 21.Urchin spine 22.Fish vertebra 23.Ammonites? encrusted in pyrite 24. 25. 26. 27.

Hi all, It has been a while and I haven't been particularly active on the forum lately as I've been quite busy, recently though I had some time available and due to fairly nice weather decided I'd go check out a new fossil site in eastern NY, which is probably the closest Paleozoic site to me. I was initially made aware of this site by @Fossildude19 who gifted me some fossils from here this summer and the unusual preservation as well as interesting fauna made me very interested. Big thank you to Tim for those wonderful pieces as well as informing me about the location. The location is a road cut exposing the Glenerie Limestone which contains silicified fossils of a variety of brachiopods, gastropods, tentaculitids and some other fauna. I got to explore up and down this roadcut for a couple of hours and came away with some pretty nice finds, at least for my first time being there. Here are some photos from the site itself: Many of the layers here are completely filled with fossils of brachiopods, spiriferid being particularly abundant. The last photo was one of the best fossils I saw there, a huge brachiopod, I believe Costispirifer sp. The photo doesn't really show scale but it was probably about 8 cm in width, and it was in very good condition. Unfortunately since it was still in the roadcut it had to be left behind, maybe one day it will weather out for someone to collect it. And now onto the pictures of my actual finds

Hi Everyone, Last month I took a trip from New York to Elizabethtown, Kentucky to attend my parents' 70th anniversary. My sister and her husband, two of her adult children, and my parents, both in their 90s have all resettled there. I try to visit them at least once per year, but my parents' 70th wedding anniversary could not be missed. It is a very long trip from the suburbs of New York City to E-Town and a stop along the way was the sensible thing to do, so I spent the night in Harrison, Ohio near the border with Indiana and only 15 minutes from St. Leon, the well known Ordovician roadcut. I've been there twice before. It is a huge outcrop, fossiliferous from top to bottom, with plenty to explore. With even a full day it is impossible to do justice to the site. As it was, I spent a half day. Most of you I'm guessing have been to or seen pictures of the roadcut. Here's a couple anyway:

I apologize in advance for the photo quality, and the fact that I did not have a ruler with me when I took the pics. I see these things EVERYWHERE. The ones pictured here are large (6-8”, 15-20cm), in limestone slabs. But I see them in smaller sizes, in rocks that I pick up. The rocks often have recognizable fossils in them, too: cephalopods, brachiopods, crinoids, bryozoans. I am thinking maybe these are internal structures, perhaps of brachiopods? I’m starting to think I am crazy…
