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.

This are two carboniferous fossils from Arlanza, Spain. The first one is a Pecopteris and the second one is a tree trunk if I am not mistaken. Do you have a different opinion or have a more specific ID? The Pecopteris The tree trunk

Is this a real Pecopteris?
Alvrr.0 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I saw this Pecopteris fossil at a shop and I like it because I dont have plant fossils in my collection. Is this fossil real?

Pecopteris villosa Brongniart 1822 Location: Mazon Creek, Illinois, USA Age: 323 - 299 Mya (Pennsylvanian, Carboniferous) Measurements: 2x12,5 cm Kingdom: Plantae Division: Polypodiophyta Class: Polypodiopsida Subclass: Marattiidae Order: Marattiales Family: Marattiaceae -
Today I made my first trip to Cory’s Landing in Portsmouth, Rhode Island to split Pennsylvanian shale. I spent about three hours there and found numerous specimens. I think they’re Pecopteris, but I would like to defer to you fine people on the Forum who have more experience than I. If anyone can give a more precise ID - or an altogether new ID - that would be extremely helpful. Likewise I found a few strips of shale with strange sectioned streaks(pictured) that I can’t identify. I’m willing to conclude it’s just nothing, but thought I would ask. If anyone would like me to try and take better pictures let me know. Thank you, all!

I am nearly finished with my review and reevaluation of all of my plant and fern findings from the Late Pennsylvanian Llewellyn Formation of Pennsylvania. I think that I have been fairly successful at identifying everything with their proper genus and species using the guide "Fossil Plants From the Anthracite Coal Fields of Eastern Pennsylvania." My hope is use this information with some nice photographs to put together an album under the Member Collection tab. However, one of the last things I need to review are my Pecopteris (or former Pecopteris) finds. I was wondering if any of the members with greater knowledge in paleobotany (@paleoflor @fiddlehead) might be able to verify my suspicions or offer an identification suggestion. It is possible that the ferns did not preserve enough to make a species identification feasible. Any help is greatly appreciated. Thank you! #1- Pecopteris lepidorachis??? - Pinnulets on lefthand side measure ~7mm; pinnulets on righthand side measure ~1cm #2- Pecopteris lepidorachis??? - Pinnulets measure ~6-8mm #3- Left: Pecopteris lepidorachis??? - Pinnulets measure ~7mm Right: Pecopteris miltoni??? - Pinnulets measure ~1.4cm #4- Pecopteris cistii??? - Pinnulets measure ~5mm #5- Pecopteris miltoni??? - Pinnulets measure ~8-9mm #6- Pecopteris miltoni??? - Pinnulets measure ~1cm #7- Acitheca polymorpha??? - Pinnulets measure ~9mm #8- Pecopteris arborescens??? - Pinnulets measure ~4mm #9- ??? - Pinnulets measure ~6mm #10- Pecopteris miltoni??? - Pinnulets measure ~1.5-2cm #11- Lobatopteris lamuriana??? - Pinnulets measure ~1.3cm #12- Lobatopteris lamuriana??? - Pinnulets measure ~1cm #13- Pecopteris miltoni??? - Pinnulets measure ~7mm

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.

Hi again! I feel very fortunate to have such great minds helping to ID fossils here. I have one other Mazon Creek fossil that I would like some help with it. It’s a fairly large (5 inch) fossil fern nodule from Mazon Creek. My first question is, is this the common fern species variety Pecopteris? I think it might be but I see some variation within the leaves (that is the fern degree terminations). Is it unusual or rare to find ferns with them still attached to the plant stock/shaft from Mazon Creek? Last question, are the oriented dots on some of the ferns fossilized sporangia? I can’t find comparable examples like this online. Thank you!

Conditions in Western PA have been unusually warm recently, with highs in the 40s and 50s. I decided to take advantage of this warm spell by getting a little bit of fossil hunting in. I decided to do a hunt focused on plants as I’ve been hunting for vertebrates for the better part of the last year and a half and, although I could never get tired of vertebrates I thought some variety was well overdue. So I headed to one of my favorite plant localities in the area. It is located in the Connellsville Sandstone of the Casselman Formation, which is in turn the upper half of the Conemaugh Group. The sandstone is around 305 million years old. The Casselman Formation holds the record of the tail end of one of the largest plant extinctions in our earths history. The prolonged wetness that had existed for much of the Pennsylvanian gave way to dryer conditions, and, as a result, the lycopsid forests fragmented. Many of these lycopsids went extinct during this event, which is known as the Carboniferous Rainforest Collapse. Conifers took advantage of these newly opened ecological niches. Their fossils have been found in this area, although I have never personally found them. Anyway, on to the fossils. Today I mostly found partial Pecopteris fronds, Neuropteris pinnules and Annularia leaflets. I’m going to include some of my better finds from other trips as well, as this trip was rather unproductive. Pictured below is the best Annularia I found today. Or Asterophyllites. I’m not sure. We’ll just go with Calamites leaves for now.

Multiple Plant Fossil - Neuropteris, Pecopteris, Annularia Plant, other leaves. *Two-sided fossil Ferndale area of Johnstown, Pennsylvania, USA Pennsylvanian - 323.2 -298.9 million years ago Fossils on both sides of specimen. This fine specimen shows two leaflets of Calamites, a member of the Calamitales which belong to the Sphenophytes. Whorls of small leaflets are arranged concentrically around a thin stem and are called Annularia or Asterophyllites. Calamites itself is the name originally given to a stem section, but now applies to the entire plant. These were indicative of humid to wet habitats such as along rivers and lake shores. There appears to be small "branches" of calamites as well. Also on this piece, Neuropteris leaflets - they are usually blunt tipped and are attached by a single stem as opposed by the entire base, like Pecopteris. Also, Neuropteris has an overall heartshape. Fern leaves called Pecopteris grew abundantly in the coal swamps of the Carboniferous Period. These leaves dropped off of a 35 foot fern tree called “Psaronius“, one of the most common Paleozoic types. With its sparse and expansive branches, it resembled the modern day palm tree. It produced as many as 7000 spores on the underside of its leaves. Kingdom: Plantae -
