I have a fossil fern (seed fern?) from Kentucky for which I have finally been able to acquire readable close ups of the leaf structure. Members of the Forum have previously been very generous with their advice; however the image was not sufficiently detailed in order to make more definitive suggestions. Various suggestions are that it is possibly a cyclopteris, a neuropteris ovata, or a macroneuropteris scheuchzeri specimen. However, the leaf structure appears to be more robust than images of these types of fossils. With the closeups hopefully a more definitive answer can be found. Suggestions are welcome. The 1st image is of the entire specimen including a neuropteris leaf (disregard the cyclopteris label). The fossil of interest is in the upper right. The remaining images are closeups. Thank you in advance for any suggestions.

Hello! I have this iridescent Petalodus tooth that I would like to preserve. Firstly, it has a severe crack though the matrix (see pictures). Secondly, is there anything that I should do with the tooth itself? What are my options? I appreciate your help.

Howdy all, I have reason to suspect that this is a heavily crushed stigmaria I found while fossil hunting today. I was in the mammoth cave region of Kentucky in a creek where I found plates of coal up to two feet long as well as this fossil. I also went down into an exposed lake bed of Nolin lake which was down the hill from the site I was at and found several of what I'm guessing are mississippian crinoids.

I’ve been air scribing this piece out and I figured it was a Mooreoceras. However, the ridge going up the front is something I haven’t seen on this species. Is it just squashed a bit? It’s a pointed oval in shape. The length is nearly 3 inches.

Yesterday, I spent about 30-45 minutes sitting in a pile of mud/rocks and practicing breaking apart softer rocks with a hammer and chisel (a little closer to shale--pretty easy to split into layers--but I'm not sure?) to see what I could find. This was one of the prettiest things I found! Northeast Alabama, US. Pottsville Formation. Thank you for your patience with my lack of knowledge. I'm currently waiting for a paycheck so I can purchase a book that will hopefully decrease my posts here!

I am going to start adding some images of my favorite finds which I call Collection Pieces. Identifications range from maybe, probably to most likely. I've only started to seriously collect over the past year. I've spent a great deal of time studying and learning Geology, as a hobby. I am located in Western Pennsylvania. At first, a map of the area. Anything in bright yellow is the Glenshaw Formation. The Ames Limestone layer exists between the Glenshaw and the Casselman Formations, which is the Orange color on the map. I have yet to explore the Ames Limestone, so I've only found fossils that exist in the marine zones below the Ames. Second and Third, are Metacoceras. The Fourth photo is of another Metacoceras. The id is slightly less likely as I can only see a few of the rounded spines. But I'm pretty sure it is one. Coming up next is a Mooreoceras that I found just this past weekend. I maintain everything on a website, that is listed in my profile. Thank you! Clint

Carboniferous Pennsylvanian seed fern specimens (pteridosperms)
ntloux posted a topic in Member Collections
I am attaching images of Pennsylvanian seed ferns that were identified by the collectors. The fossils from Kentucky were generally found in the shale around closed down coal mines on family farms. Hopefully these images may assist others in identifying their specimens. Comments/suggestions/corrections are welcome and I also would appreciate specimen identification beyond the genus level for many of the specimens. The first image is of a Pennsylvanian alethopteris specimen from eastern Kentucky: Pennsylvanian alethopteris from eastern Kentucky. Pennsylvanian cyclopteris (upper right) and macroneuropteris specimens from eastern Kentucky. Pennsylvanian eusphenopteris specimen from eastern Kentucky. Pennsylvanian mariopteris specimen from eastern Kentucky. Pennsylvanian Pecopteris plumosa specimen from Upper Silesia in Poland. Pennsylvanian pecopteris specimen from eastern Kentucky. Pennsylvanian sphenopteris specimen from eastern Kentucky. Pennsylvanian crenulopteris specimen from Mazon Creek, Illinois. A helpful Forum member suggested this could be crenulopteris acadica. This last Pennsylvanian specimen is from Mazon Creek, Illinois identified by one individual as Lobatopteris lamuriana and in addition a helpful Forum member suggested that it is possibly a diplazites unita.- 12 replies

I have 4 Pennsylvanian stigmaria specimens of which only one was specifically identified as a lepidodendron by the collector. I am hopeful that others might have useful suggestions in terms of better identifying the others. The 1st image is of a Pennsylvanian lepidodendron stigmaria specimen from Kentucky. This is my nicest one because not only is it better identified, it also illustrates rootlets and buttons. Image 2 is of another Pennsylvanian stigmaria from Clintonville, Pennsylvania. This appears to be the most common type of stigmaria that I have seen. Would anyone have suggestion/possibilities that would better characterize this specimen? Images 3 and 4 are a Pennsylvanian stigmaria with a heavily degraded label. Image 4 is a closeup of the specimen in image 3. I was able to decipher parts of the label and it was apparently collected near Middlesboro, Kentucky. The rootlet scars on this specimen are much less three dimensional that the rootlet scars on the specimen in image 2. There may be a comment on the label about the rootlet scars having a spiral character. Would anyone be better able to characterize this specimen? Image 5 is of another Pennsylvanian stigmaria from Kentucky. It has many similarities with the specimen depicted in image 2. I also have one very heavily weathered stigmaria from Oklahoma that is very similar to the ones depicted in images 2 and 5; I didn't think it was worth uploading an image. Comments and suggestions about the others would be appreciated.

Hello, I found what looks like a worm on a block of limestone too large for me to split. So I took a picture of it. It is about 4 cm. The limestone is Carboniferous, Pennsylvanian and from the Glenshaw Formation. Thanks for the help!

I am attaching images of calamite and annularius specimens in my collection. Because their appears to be some debate among the experts on the relationships between calamites and sphenophyllum and asterophylloides, I am also including images of these specimens. I would welcome comments, suggestions or corrections from viewers. Further species identification would also be appreciated. Image 1 is of a Mesocalamite specimen that was among other Pennsylvanian fossils from Kentucky. Image 2 is of another Pennsylvanian Calamites from Kentucky. Image 3 is of a Pennsylvanian Calamites specimen from Alabama. Images 4 and 5 are Pennsylvanian Annularia leaf specimens from Mazon Creek IL. Image 6 is a Pennsylvanian Annularia radiata specimen from the Westwalian A & B, Lower Silesian in Poland. The contrast between the fossil and the underlying rock is so poor that I did alter the exposure settings in order to better view the fossil. Image 7 is of a Pennsylvanian Sphenophyllum specimen from Mazon Creek IL. Image 8 is of a Pennsylvanian Sphenophyllum cuneifolium specimen from the Westwalian A & B, Baszkirian, Lower Silesian in Poland. Again, because the contrast was so poor, I altered the exposure in an effort to obtain a better picture. Image 9 is of a Pennsylvanian Asterophylloides specimen from eastern Kentucky.

I have 2 Pennsylvanian fossils from Mazon Creek. They have previously been identified as crenulopteris and lobatopteris lamuriana. Presumably the crenulopteris specimen is a seed fern; however, I am unsure about the lobatopteris lamuriana specimen. Presumably the lobatopteris was once labeled as a pecopteris so is it still considered to be a seed fern? Any information or suggestions would be greatly appreciated. The first image is of the lobatopteris specimen, The next image is of the crenulopteris specimen.

Hi, At Trefil quarry, Wales, I found these. They were found very close to one another. This site was a carboniferous coral reef. If anyone can ID, or point me in the right direction, it'd be much appreciated. Thanks!

HI all, I found this while searching the Bond Formation Pennsylvanian road cut in Oglesby, Illinois. Any Ideas? Also, Here is a bonus pic of a Peripristis semicircularis I am prepping out. There are a few fossils I am working on right now, but I plan to make a post of my trip once things are cleaned up. Thanks for looking!

I'm in the process of photographing and cataloging specimens from a new site and thought some here might enjoy seeing some specimens as I go. These fossils were collected in eastern Illinois from the roof shales of the Herrin (No. 6) Coal. They are middle Pennsylvanian (Desmoinesian) in age. The Herrin (No. 6) Coal is the second to last coal member of the Carbondale Formation. For reference, the Mazon Creek biota occurs in the Francis Creek Shale Member, which overlies the first coal member of the Carbondale Formation, the Colchester (No. 2) Coal. Here's a general stratigraphic section of the Carbondale for reference. This biota has similarities to the Mazon Creek biota, but the flora especially is quite different. The fauna so far seems typical of terrestrial Pennsylvanian sites: bivalves, branchiopods, indeterminate arthropod parts, and a single shark egg. This biota is not well studied, and thus many names here are provisional pending a possible formal study. Scale bars are 1cm unless noted otherwise. Dunbarella striata Calamostachys tuberculata Alethopteris gibsonii Cyperites bicarinatus

I found multiple pieces of this rock which each vary in size but the shape and structure is the same. There is banding and in the middle of each is a cellular structure looking material. Is this some sort of plant? I am in Mississippian strata Indiana USA

Northeast Alabama. Pottsville Formation. This is embedded in a large boulder (with multiple other fossils) that we dug out of the ground within the past 6 months. I'm not sure yet how to remove or clean it. Not the greatest quality photo (my apologies), but I am assuming this is Lepidodendron bark?
