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

Need some help identifying this fossil from North Attleboro, Massachusetts
Dino2033 posted a topic in Fossil ID
I found this rock with both a Neuropteris scheuchzeri and this mystery fossil. I have seen nothing quite like it on the web but I probably just missed it. Part of is seems to overlap the Neuropteris and it seems to have a wide and thin part with the wide parts being further from the Neuropteris. Any help is greatly appreciated. Last picture is through a microscope and focused on the overlapping part.- 2 replies

Greetings! This is my first post, and a Newbie, although I’ve learned much from this forum already, thanks to you all. And now I’ve got a burning ID question: About 10 days ago I came across these pieces. All found together, loose on a hillside in the Sangre de Cristo foothills of northern New Mexico, Pennsylvanian subperiod, Flechado or Alamitos Formation. P. K. Sutherland and B. Kues state this area was probably a series of shallow bays and deltas. Most fossils here are marine. So, my first thought was fracture pattern, crinoids or worm burrows, but then I noticed the woody stems and what looks like short pieces of Calamites - horsetail stalk (see detail photos). After perusing other posts on this forum, these stemmed feathery swirls look to me like Cyclopteris or Neuropteris(?) They are imprinted in layered slabs of golden brown micaceous sandstone, unlike the marine fossils nearby that are in gray shale and limestone. FYI, my index finger is about 8 cm long. Piece A Piece B Piece C Side 1 Piece C Side 2 (flipped vertically) Piece C Detail - Calamites? Piece C Detail - Neuropteris? Piece D together (seam is in middle left to right) Piece D positive and negative, rotated clockwise from previous photo. Piece D Detail - Calamites (rust-colored in upper left)? Thanks very much for looking!

Went to a site in central PA today and collected some Llewelyn formation ferns and other Carboniferous plants. Second opinions on the following are appreciated! 1, I thought this is an Alethopteris but the leaves look like they can also be some immature Neuropteris with compound leaves with the leaves pressed together. 2. Is this Sigillaria bark? 3. Wasn’t sure if this is Lepidodendron bark. These crosshatched stem-looking prints are quite common at the site 4. is this a Calamite print? 5. I am fairly certain this is Neuropteris but just would like to be sure. That’s all. All and any help is appreciated! Thanks in advance and let me know if scale is needed.

Poorly Preserved yet almost complete Neuropteris sp. (lindahli?)

A long time ago I had neglected to turn over a piece of Winterset limestone that contained ferns and to my surprise on the back was this specimen! I was told it could be a Neuropters lindalhi a couple of months ago and never uploaded it onto this site.- 1 comment

A nodule from Mazon Creek opened up this week and revealed a nice fossil. I believe it is a Neuropteris Seed Fern Leaf based on pictures examined. The curious thing is the additional leaves that exit the stem. Is this typical or representative of the species???

Another find in Pit 11 of Mazonia-Braidwood complex. Found already open on the ground. I was unable to find the other half. It looks a bit like the images of Neuropteris fimbriata and Cyclopteris trichomanoides in Jack Wittry's "The Mazon Creek Fossil Flora."

Hi all, Upon examining some of my finds from this hunt about a month ago, I realized that there was an anomaly on one of the Neuropteris ovata pinnules. Initially I brushed it off as nothing more than an anomaly, but last night while I was doing some reading I came upon an intriguing paper on insect galls from the Carboniferous. Some of the gall fossils included bore a striking resemblance to the gall on my frond, and so I figured I would make a post to see if any of you had an idea on what it could be. Here is the frond, in full view: Closer inspection of one of the pinnules reveals a small, oval-shaped bump: This bears a striking resemblance to some of the galls included in this paper (it is not paywalled). Specifically, it resembles #7 in the first figure. I hesitated to include the image directly in this topic so as to not violate any Forum rules (if it is not a violation I can include it here as a reply). https://www.researchgate.net/publication/250613622_The_Seeds_on_Padgettia_readi_are_Insect_Galls_Reassignment_of_the_Plant_to_Odontopteris_the_Gall_to_Ovofoligallites_N_Gen_and_the_Evolutionary_Implications_Thereof Although it superficially resembles a gall, I am looking for other opinions as I have no experience in this field. Here are my thoughts on why it could, or could not be a gall: It could possibly be a gall for multiple reasons. First off, the morphological similarity is quite striking. Secondly, the paper states that ", occurs commonly on a variety of seed-fern foliage throughout the late Middle Pennsylvanian to Early Permian". This is from a late Pennsylvanian deposit (Connellsville Sandstone of the Conemaugh group) so it fits quite nicely into that time frame. Also, epibionts are quite common in this deposit, specifically Microconchus. They are preserved in a relatively similar fashion (mold-cast). There are a few reasons why it could also not be a gall. First of all, I have never heard of galls coming from deposits in the Appalachian basin, though this may simply be due to my own ignorance and/or a lack of literature. Also, this anomaly is isolated, which is a derivation seen from many of the galls included in the above paper. Finally, random nodules and concretions do occur sporadically throughout this deposit, so it could always be mineral growth. And finally, my simple lack of knowledge prevents me from making a confident ID either way. So, what do you all think? I'd love to hear some of your opinions as to what it could be! And on the off chance that it is a gall, should this specimen be donated?

I have this fossil here which at first glance I perceived to be some kind of seed, however I’m not sure. These are both from the same individual, just the positive and negative sides. It is just shy of half an inch long. It was found in the North Attleboro section of the Rhode Island formation

Macroneuropteris macrophylla, a Neuropteris-like group seed fern, or Fern. Not sure if the matrix is shale. Could this be from Mazon Creek. Illinois? 4 x 3 5/8th x 2 1/2 inch. I am rather sure it is North American. Macroneuropteris macrophylla, a Neuropteris-like group seed fern or Fern. Age: ca 314 Mya

Hello! and I hope you are having a wonderful afternoon! I found these two plant fossils and was unsure to what they might actually be. They look a lot like modern seeds but I know I am not always informed and I keep having a slight suspicion they could be apart of some other plant material! If anyone could help identify and confirm these plant fossils I would be very grateful! I have found leaves from Neuropteris sp , Cyclopteris sp, and a few other plant species in these types of limestone! Info that I could gather: Location: Missouri Time period: Pennsylvanian Formation: Possibly Upper Winterset Limestone Specimen #1: Two halves of one seed? (roughly 9mm) Other half: Specimen #2: Larger and wider seed? (roughly 3mm) I unfortunately do not have the other half to this one!
