Could you help me ID this plant fossil (stem?) from Morocco? Scale is in cm.

I was inspired by @Mark Kmiecik and his quality photographs to finally learn some basic image editing. I had this beautiful Crenulopteris acadica fern open yesterday and figured it would be a good specimen to make a first attempt. Let me know your thoughts.

Hi, I am having trouble identifying what appears to be a plant fossil. I found it recently at Ft. Gibson Dam in Oklahoma. The most tell-tale markings are in the lower right hand corner of the attached photo. Any I.D. will be much appreciated. Also does anyone know the formation? Pitkin Ls, from the Mississippian is at the dam, but my ROCKD app had the formation as Atoka, which is Pennsylvanian. Thanks to PetrolPete for guiding me to this site.

Fossilized Plant Stems? or just cracks in a rock filled with sediment (Missouri)
Samurai posted a topic in Fossil ID
All of these are from the Winterset Limestone Formation and dated to the Pennsylvanian period Found in Missouri I found this in a rock that was completely covered in these structures and had many layers to them Here are a few I decided to take home with me Natural color in daylight (measurements are in the last photo of this specimen): Specimen #2 -
This one has been sitting in my "interesting but I have no clue" pile for a while. When I found it, I was splitting limestone laying in the stream. I've found that when you split limestone, immediately after splitting you'll get a couple moments of a sharp looking specimen before things start to oxidize. The limestone is a very dark gray, or almost black color. You either see black limestone or white calcite pieces while splitting. I split this particular piece open and right in the middle was a 3-4 cm long, 8 mm wide gold looking rectangle in the middle of the flat broken limestone. I thought I wouldn't get to recover it, but one hammer hit later it popped out and I was able to save it. I do find that plants in the limestone seem to get the gold or pyrite type preservation. I've found one small straight shelled cephalopod preserved like this. But overall, it's very rare here. I have maybe 3 or 4 larger pieces of what I'd called pyrite type material I've recovered. Below are some stacked microscope photos of it. The scale in the first photo is 1 mm for each mark. You can see the grain that runs left to right. This looks like wood to me, but I haven't had that confirmed before. The next two photos are a view looking from the bottom to the top of the first photo. What has me most curious are the perpendicular grain marks that are found in this area. They don't seem to just be on the outermost layer, as you can see more deeper. I'm not sure if this is some sort of perpendicular crystal pattern, or it's just the shape of the original material that was replaced with the mineral. And maximum zoom. A stack of 12 microscope images taken through the lens in the same area of the above photo. And that's it. Is this a small piece of woody material that was preserved in the sea? I wonder if vinegar would clean this up or destroy the mineral as well.

Alnus stenophylla Miocène (Messinien)Cantal France

Alnus stenophylla Miocène (Messinien)Cantal France Thanks Marguy for this great fossil! -
The smaller specimen pictured opened this morning and reminded me of the larger specimen which I found earlier this year. They are very similar looking. My first thought was Cordaites borassifolius due to the linear striations, but the specimens are fragmentary and the preservation is not great so they could also just be indeterminate wood fragments. I don't think I've seen a Cordaites specimen in person before so I am not positive either way. Any thoughts are appreciated.

I collected this specimen last year but still can't decide on an ID, it's pretty fragmentary. Any thoughts are appreciated. @bigred97 @flipper559 @stats @Nimravis @deutscheben

It was found in a Devonian exposure in western Virginia. There are orthocones, brachiopods and other aquatic life in the exposure (with some being pyritized), along with other plant fragments in the area.

Anchor Point Alaska Miocene plant materials
Sjfriend posted a topic in Partners in Paleontology - Member Contributions to Science
I have been in contact with the head of the University of Alaska Fairbanks and Museum for a couple years showing some of my better plant fossils from my area. Miocene age, Beluga Formation, This last week I had a Masters Degree student come and visit my collection and my local site. She is going to do her thesis on the local miocene flora. There are papers on plants presumed to be older and younger but none from this section of the formation. I donated approximately 100 lbs of specimens to the University of Alaska Fairbanks Museum of the North to be used by her then put in the Museum's collection. Based off the papers from other Alaska sites, it appears to be a mix of Salix, Betula, Alnus, Ficus, Populous, Metasequioa, Glyptostrobus, Taxodium and probably others. I know there are at least a few that are not described from this formation based off looking through the papers. Included in the specimens are leaves, twigs, branches, aments (cones and catkins) and other inflorescences. I know there are cones from 3 different families based on shapes and sizes. The student and her professor were quite thrilled and impressed by specimens they were able to take back. I will be donating a lot more from my previous trips after high grading them. And, now I am helping as an offical on-site field agent for this now official University project. So all my digging here for the next 3 years (expected length of project) will be for the university museum. Fine by me as plants are not my #1 fossil to collect.

Hi everybody, today I took a trip to 2 sites in the East Berlin Formation. I didn't find anything too spectacular, but there was lots of really cool geological features. This first site is a roadcut in the formation, I believe that I found a sea bed imprint? I'm not sure on it though. Some views of the area I checked out The possible sea bed piece, I'll get a better photo soon. The Second Site View of the site from the pull off The black shale spot, there seems to be multiple different shale layers stacked ontop of eachother here. I spent most of my time collecting in this spot. The orange layer is really odd to me, I'm not sure what causes it. The shale splits pretty easily, which is promising for plant fossils (and maybe fish fossils?) In the corner you can see a little salamander (or newt?) tail. Plant fossil? This looks like a partial plant fossil, but I'm not 100% sure. Another possible plant fossil? Looks fossil-y. A better look at some of today's finds All in all I'd say today was a success, I'm planning on checking out the sites again some time soon. If you'd like closer photos of the pieces I found let me know, I'd be glad to.
