From the album: Plants of the Lewellyn Formation
Leaf impression in siltstone Carboniferous period Ralston, Pennsylvania -
A very small group of us ventured into the wilds of northern PA last weekend, equipped with masks and a permit to poke around a state wildlife preserve with Carboniferous Lewellyn Formation exposures. It was a gorgeous day and the colors of the limestone really shone in the sunlight. As we got there, a pair of permit-less fossil poachers were just leaving. How do I know that they didn't have a permit? Because they absolutely did not follow the rules. Since it is a wildlife preserve, it is important that anyone looking for fossils not leave craterous holes in the ground and replant any plants that were uprooted in the process of digging said holes. They left holes everywhere. Our intrepid permit holder filled in most of the holes so that she could keep getting permits in the future. For this reason, I'm not going to be any more specific about the location. That said, there were so many wonderful plant fossils to find! The site is remarkable for its red, orange and yellow limestone, which makes for some terrific, high-contrast fossils. Many of them had crisp details. What's more, there was quite a variety.

Hello! I recently went to Grand Ledge, Michigan. This area is part of the Carboniferous, and more specifically the Pennsylvanian period. I found this fossil that appears to be scales. It’s not an imprint either, the scales are elevated. In the surrounding rock there are cordiate fossils and some kind of clam, I found ferns in the area as well. I believe that it was a swamp land way back when these were all alive. An ID on what kind of plant or maybe even fish scales would be awesome! Thank you!

Last week I found what I think is pyritized wood from Pit 11. Is this the case? And if so, is there anything more scientific I can call these specimens? 1) 2)

Yesterday I received a parcel from a member of the forum, containing fish and plant fossils from the Scottish coal measures, as well as a tooth which I found in West Yorkshire (UK) and sent to be prepared. My favourite of the Scottish fossils is a tooth which I am fairly confident is Strepsodus sp. Since little is known about Rhizodont teeth, it’s often very difficult to put a genus name to a particular species. Despite this, when I first saw this tooth the shape immediately made me suspect it is Strepsodus, so I decided to have a closer look at the striations. I was pleased to see that the striations look a very good match to Strepsodus sp in my opinion. I am therefore about 90% sure it is Strepsodus, and it’s the only tooth in my collection that I would call Strepsodus with any confidence. Sorry for the low quality photo, it’s quite small (5mm) and the shiny surface made it difficult to show the detail. Here is the tooth from West Yorkshire, before and after prep. It measures 12mm long, and is the largest tooth I have found in the Yorkshire coal field. It also the best preserved coal measures tooth I have found. This tooth comes from a mussel band, in which fish remains are quite rare, apart from in very thin fish layers which sometimes occur in the band. However, this is not within one of the fish layers. I’m not sure what fish this tooth is from, I suspect an identification would be almost impossible until more information about these fish is discovered and published. It is from the Pennine Lower Coal Measures formation (upper Carboniferous).

So, I found these rocks on an late carboniferous site in Brazil, the rocks are sandstone, rhytmites, diamictite and shale. I searched and on that period, the site were an shallow ocean/swamp after a glaciation period. I found an article that studies megaspores from a really near site fron this one ive been. Ill post pictures of some of my founds, some of them dont really look loke fossils, but they were very curios so i wanted to ID them. I really appreciate all help!

From my collection of St Clair plant material - any ideas? Less than half a centimeter thick, about two inches long.

Fossil hunting in Virginia/West Virginia/North Carolina
the_abyss_blinked posted a topic in Questions & Answers
I hope this is the right place. I am hoping to find some spots in these areas. I'd prefer Carboniferous as opposed to Devonian, or Miocene/Eocene. Would any of you know any spots? Maybe road cuts, or abandoned quarries those sorts of places? I'd be willing to pay for access if need be. If you don't feel comfortable outing it, please PM me. Thank you! -
I found this upper Carboniferous tooth in the Yorkshire coal field a while ago. I am unsure if it is from a fish or an amphibian. It measures 5.5mm long. Any help to identify it would be greatly appreciated. Thanks, Daniel

Hi Everyone, I found this specimen a while back and have been trying to identify it but have been unsuccessful. Its from a layer of shale within the Winterset Limestone, Kansas City group, Upper Pennsylvanian, Carboniferous. Scale in mm. I flaked it off a bigger piece that had bivalves in it which I'll post below. The depth of the flake is about 1/4th of an inch (6.35mm) thick. The fossil doesn’t carry through to either side of the flake. The piece at the top is the same specimen just what came apart when I cracked it. At the moment my guess is that it might be a bivalve of some sort but I can't find any that look similar. Here are some other bivalve species that were in the same section. The color difference is from me scrubbing it with a brush which removed the gray matrix. Any feedback is much appreciated as I can't find anything close.

This is a trip I took last year as we decided to make the trek to Washington DC for our family trip. I would definitely recommend a trip there for the museums alone if anyone has been thinking of going. Even on our non fossil trips, I try to plan a fossil excursion or 2. We got to the site around 11am, and it was quite hot as it is out in the sun. I don't have any pictures of the site itself, but you basically park on the side of the road, and hop over a barrier, and you are right there. Thank you @minnbuckeye for recommendations on parking as safety is always paramount when the family is with me. Thank you to @TNGray for his wonderful webpage once again in helping me find some easily accessible sites for the family. I only got to spend about a half hour at the site as the family was wanting to get moving home, but here's about half the fossils I brought home.

All the local Kmarts went the way of the dinosaur and went extinct last year. I bought a couple display cases for $40 each. I brought it home and just a month ago filled it up with fossils. The wiring was cut from the store in a hurry, so I just left it as is. I ordered a plug and rewired it this morning. The light makes a huge difference.

Found something I haven't seen before while hunting in Pennsylvanian limestone a couple weeks ago. I feel like this is poorly preserved plant material but there are not many discernible features, even under magnification. Any thoughts?

Mystery Carboniferous Plant - just another fern or something else?
cameronsfossilcollection posted a topic in Fossil ID
Found this in some Pennsylvanian aged shale in Ambridge, PA at the well known mahoning exposure. It doesn’t have visible pinnae like the ferns I’ve found in the area, but it could just be a strange preservation. Any ideas - is this just a fern? Thanks!

Rhizodus is probably the most well known Carboniferous fish. I have seen Rhizodus teeth over 20cm in length, which shows the huge size this fish could reach. Fossils of Rhizodus are quite difficult to obtain due to their rarity and because most of them were found a long time ago. I do however have two teeth from Rhizodus. I intend to allow these teeth to be studied by experts if they are of interest to them. The first tooth is a tusk tooth from Newsham, Northumberland, England. It measures 37mm long. The second tooth is from Cowdenbeath, Fife, Scotland. I believe this comes from the Limestone Coal formation, Dora opencast. It measures 42mm.

Just read @Bonehunter's post and discussion with @Missourian about an unknown Pennsylvanian plant and it got me wondering the same about this specimen. It looks like wood to me, but I can't find any Upper Pennsylvanian wood that looks similar. I'd love your thoughts on what it might be? I found it near where I found a large tabulate coral specimen. It's from the Bethany falls limestone group. Would that make it drift-wood? What do you think the weird textured pattern on the outside surface is? @digit guess my creek is producing more stuff I can't identify Thanks,

Thought I’d make one of these posts on the chance that I end up spending a lot of time posting here. Hey there everyone - I’m Cameron. I’ve used this site for a long time but never made an account until a few months ago. I’m from central VA and travel to the Lost river near Wardensville just to find bits of Eldredgeops, and I’d love to talk fossils with anyone on here as nobody in my offline life is very interested in the topic. I hunt marine outcrops from the Mahantango and Carboniferous swamps in Pennsylvania, and I’m building up a fairly decent collection. Ive found many fossils that I don’t have a clue about, and learning anything about paleontology makes me squeal like a little girl, so I’ll definitely be posting in the ID section a lot! I’ve even found a conulariid in WV which people seem very excited about! I look forward to posting more here, hopefully I did this post correctly.

I feel like this is a smattering of disarticulated fish bones, but I'm not positive. The preservation is not amazing so even under magnification I'm not sure if these are bone or not. Found in Pennsylvanian black shale in Illinois. Any thoughts? @RCFossils Various levels of magnification

Bivalves always challenge me. If the ear (is that the right word?) on the left wasn't present, I would have called this Dunbarella sp. But the rounded ear doesn't match any species of Dunbarella I've seen. Maybe another genus, like Aviculopecten? Not sure. From Pennsylvanian black shale in Illinois. Thanks for any help.

So for some time, I've had an interesting idea of displaying multiple types of fossils from the same area together in the same display case. I ended coming up with this quick and easy idea, though it was many months in the making. I found the box itself on Amazon. LINK It's nice because it has a soft velvet lining with the grid itself being removable and customizable, so you can display things how you want. A lot of my finds here in Missouri are smaller marine invertebrates, so this box worked well. I'm rather proud of myself on how this turned out. Brachiopods, bryozoans, blastoids, gastropods, corals, and crinoids all made it in this display, and were all found at the same location. All of these fossils came from a little town called Tightwad, Missouri. Missouri has a variety of Carboniferous fossils here, and almost nobody collects them around here from what I see. (I often get weird looks from people when they see me with my pick and my eyes fixed to the ground.) But alas, fossil hunting is a great addiction to have in my eyes because every day is a treasure hunt.
